Hello!
Let me just start off by saying I am very pleased with my S6 Edge, it is such a big leap in pretty much all aspects from my previous S4.
I only have one issue, and that is a pretty annoying one.
The GPS is not at all as accurate as the S4, and it loses signal completely every other minute or so - sometimes more often.
I have tried both Google Maps and the main reason why I want the GPS to run smoothly: Waze, same issue in both of them.
Lets not even discuss Runkeeper, giving me ridiculous run times.
The app GPS Test, when run on both S6 Edge and S4 simultaneously, tells me that the S4 finds and locks on to 2 more satellites (16 vs 18) with a
constant accuracy of 4-8 m.
The S6 Edge is mostly on 12 m (never lower), but jumps all the way up to 32/48 m for short moments. As mentioned before it cuts out completely for a brief second once in a while making it even more unreliable.
Factory reset made no difference.
Is this something that anyone else is experiencing?
Could it be a hardware defect?

Same here. This problem is also discussed on a german forum. I don't think it's a hardware defect. Maybe caused by the glass/metall material or bad antenna design, or a software bug. I don't know. You are not the only one who is not satisfied with S6 Edge's gps performance, but many people will not even notice that the accuracy of the s6 gps is poor. An accuracy about a maximum of 6-12 meters is, in my opinion, not acceptable for a todays high-end phone. I hope Samsung will fix it. Otherwise i will sell my S6 Edge, because i track a lot, use it for running, geocaching and all these nice things :cyclops:

This requires rooting your phone. I am getting exactly the same issues, I assumed that this was just my handset, now it is happening to others.
Runkeeper seems to think I have run an extra 0.5 miles, which clearly isnt the case

Hopefully this means the GPS is supposed to perform better than what I experience.
I will be returning my unit as DOA.
Please show us some results with gps test den haag...

I've been having the GPS issue as well and narrowed it down to a few things. First, if you activated the battery saver, GPS is virtually unusable. When you go to shut off the gps and exit all gps using applications, it continues searching for GPS. A reboot is the only thing that stops it. I did not find that to be the issue when battery saver is off. I haven't tried Runkeeper with no battery saver but will report back when I do. I think it is a hardware thing. I've had multiple phones, including the Note 4, and the GPS was almost flawless. By the way - this is my second phone, same issue.

It concerns me that you have had two phones with the same issue, I was banking that it is my handset only. Has anyone reported the issue to samsung?
GPS Issues on the Galaxy S6 Edge
Same issue here. I use the Nike+ Running app and have trouble getting/maintaining a GPS lock.
On a clear day with an unobstructed view of the sky the GPS drops out every few minutes (see image below) Going to report to Samsung, hopefully it's a software issue that can be patched and not a hardware design flaw.
I'll follow up here when I get a response.

I drive every day for about 3 hours and i use the galaxy s6 edge as sat nav (using the tomtom app) and the gps in this phone is one of the most precise and reliable i've ever used.
When i'm driving it usually locks 15-16 satellites and the precision is ALWAYS 3 meters (sometimes it jumps to 4 but only for a couple of seconds).
I tested the gps as soon as i received my phone:
I drove for 1 hour and 30 minutes with the "gps status" app open and the accuracy was stable to 3 meters for the whole trip!!!!!
I also own a galaxy s4 and the gps on it is no match for the one on the galaxy s6 edge.
The S6 edge is also extremely accurate in city centers with a lot of skyscrapers where, for example, my galaxy s4 would "fail".
I tend to be very picky about gps precision and i changed different devices because of this (the nexus 5 for example) but i must say that the accuracy and precision of the galaxy s6 edge really surprised me.
Mine drops as well. I could be outside, have a lock on 18 satellites and it would go down to 0 in an instant. Lock would be reestablished after a few seconds.
Same issue here - in Waze especially. Alot of areas I never had issues with my S4 or even S5, the S6 Edge seems to be 'Searching for GPS) - very unreliable, even when I was on a major highway it dropped out randomly. Thinking its software but there hasn't been any updates that I've seen

Got a few "GPS Signal Lost" notifications while using Google maps today. Bad enough, I can't get Maps to read out street names. It can't even hold a lock... lol
Gps indeed not very good
I Always use runtastic for running
But indeed is the gps is not that great vs my old Phone and vs the tomtom gps watch..
I hope there is a fix for it because i need it very bad..
Same here, GPS performance is lacking to say the least. I truly hope it's a software flaw!

Note: I do not have my phone anymore - 02 staff opened another new phone while I was there returning mine and found same issue. See later posts for details.
HOWEVER: I think, as mentioned later on in this thread very usefully - that we really need to have some requirements for testing, some Metrics, othewise this will (continue) to become a competition of will, emotion and opinion rather than the facts we need.
This thread is proving useful to quite a few people in deciding what to expect from the SGSII and their GPS requirements from it. Let's keep the feedback coming in.
PLEASE INCLUDE IN ANY FEEDBACK THE FOLLOWING INFORMATION:
TtFF (time to first fix - although not the primary interest in this particualr thread - interesting anyhow): cold/hot, stationary/moving, indoors/in car/in pocket/urban area/open field.
Accuracy: after 10/30/60 seconds (in all the above situations), as given by the phone and as measured vs a known landmark
Number of sats and SNR: after 30 seconds take 3 snapshots in 5 second intervals
Wifi on/off, "use wireless networks" on/off, and if the S2 has the "use sensor aiding" setting whether that's on/off.
Lastly, firmware release could be helpful.

ORIGINAL POST:
Ok - just got my second Galaxy S II and am loving the speed and the update from my original SGS.
I had such severe problems with the GPS in my original SGS that it was virtually unuseable. With the SGSII I hoped that would be fixed as I use Google Navigation a lot.
Now I find that there are very similar issues with the Galaxy S II as there were with the original Galaxy S.
Specifically the SGSII has improvements in that it finds satellites (I usually get a lock on 6-8 of a maximum of 12) but that the accuracy never goes better than 26-45 meters and fluctuates which makes matters worse. Something is not quite right with the way the SGSII uses it's locks on GPS sattelites as it doesn't translate to the accuracy it should.
I've stood outside and compared side by side the SGSII and an (old now) HTC Hero and the number of satellites locked are similar and the time to lock is similar - but significantly the HTC Hero gains a high accuracy of 12-3 metres and most importantly it keeps this accuracy stable. The SGSII on the other hand fluctuates with a similar number of satellite locks and sometimes the accuracy goes down to 60-70 meters briefly.
Quite honestly - I'm shocked that Samsung who have such huge R&D budgets and masses of experience in the handset market could not have nailed this problem from the original SGS being so bad. I almost can't believe that they could have repeated the same issue twice. Granted the SGSII is *better* - significaantly so compared to my original Galaxy S - but then that doesn't mean it's good or acceptable given how extremely bad the accuracy was on my SGS.
I'm taking my handset back to O2 tomorrrow to see if they can swap it out for another one. Hopefully slight variances in manufacturing will come into play and the replacement will be better. This is simply not good enough from Samsung and I really wish they would get their act together.
Also - just want to say: Please please please can people understand the difference between GPS fix time and GPS accuracy. It's getting to be a problem when people declare their GPS fully working when their GPS fix times become quick - totally ignoring fix accuracy and it happened a LOT with the SGS. GPS accuracy is completely different to GPS fix time although of course GPS fix time is better if it's quick. I'd rather have accuracy over fix time anyway because what's the point of a quick but inaccurate and "wobbly" GPS fix? Certainly no good for Google Navigation.
Engadget have posted a video declaring that the GPS in the SGSII "really works". Well - the map was zoomed out quite a way and they also turned off Wireless which was known to help the original SGS get better accuracy because it was believed that wireless was somehow interfering with the GPS functionality to some extent. So: Engadget did not zoom in far enough. They did not show the accuracy. They turned off wifi. Therefore they cannot claim it's "fixed"
What are other people's experiences: Can we get some posts here showing *ACCURACY* and how stable it is - NOT fix time? GPS test in the market is a good tool to do this. Google Maps is good enough.
Can we also get some feedback here about Google Navigation performance. Is there any drift. Does the lock stay stable?
My SGS2 just works fine.locks to satellites in about 5secs, connects to 12 satellites overall.I've tried it over and over.i guess something must be wrong with your phone

No just something wrong with you, great example of not reading the actual post, he is talking about accuracy not amount of satellites or fix times as he stated in his post.
This is bad news, hope it can be fixed with a update, if it's the case with all handsets. I'll be getting mine on Friday, let you know how mine works.
ugh.. i dont wanna hear this.. *positive thoughts* * positive thoughts*
Locked pretty fast, accuracy never went above 60ft after the initial up and down. Got to around 20ft for quite a while...I'll test it tomorrow when I'm out and about but it looks alright. Tbh my SGS's GPS lock on and accuracy is brilliant too...I use it quite often for driving and it does it's job.

Well being objective - my post reflects my own experience with one handset so let's hope it's isolated and I've been unlucky - would be great to get your feedback when you get yours.
I do think that this is the sort of problem that *could* be fixable with software because getting the fixes on satellites seems reasonable - and that's the hardware doing it's job (I think?).
The poor, jumping accuracy is exactly what I had seen in two videos posted on YouTube for the S2. But I've also seen track logs that show very good accuracy, much better than I've seen on any Galaxy S. It almost makes me think GPS Test may be showing some anomaly in the accuracy reading that doesn't actually translate to the mapping position, although not sure how that's possible. Very hard to tell the full story at this point.
The problem we have is sampling error. As many of the S owners know all too well one test or one phone does not tell the tale. One day it can seem to work ok, and a day later be way off. Also, there can be huge variations between phones, with some working perfectly and others not working at all. Of course, that can happen, but often times the replacement phones were no better or even worse. The only way the S2 will prove itself is over time with many users reporting.

There is a thread where the GPS accuracy was tested with the app My Tracks.
http://forum.xda-developers.com/showthread.php?t=1056973
You could try that app to verify GPS accuracy.
EDIT:
Could you report the accuracy when using My Tracks ?
Hmmm, bad news!
The other happy owners of the SGSII should please test their GPS-accuracy,too!
[Q] Does anybode know how the displayed "accuracy" is calculated on the phone? Does the cursor jumps over the map when the accuracy is low?
Sorry I'll be totally new at Android with SGSII and I don't have much experience with gps-devices.

As for calculated, no idea, but in Maps and such it's displayed as a blue circle. The better the accuracy the smaller the circle.

Thx for the info
This accuracy figure, as I understand, is to an approximation.
GPS is just a system of clocks. They are super accurate and all in sync. That is monitored and ensured by the US Military who run it.
When you stand at point A, and are in the northern hemisphere and have a good view of the sky, you should have say 12 satellites.
That means you are receiving time signals from twelve clocks. Each has a unique 'tag' on the signal so you know which clock sent it. If you compare these times though, you will find a tiny difference between each due to the time taken for the signal to reach you.
By doing some math, the delay is calculated and speed is equated from distance and time. Now, by drawing a "plot" of each month (it sends its location in space every 30 seconds, and assisted gps sends the location via data network), we can draw a circle from the satellite, with radius equal to that of the distance calculated.
Remember this is in 3D. It is fairly likely you are on earth do realistically you potentially are in only a small segment of this sphere.
Now add another sphere for each satellite. By triangulation your location is calculated to be within a small area.
To understand it better, draw it on paper. Get a set of compassrs and draw a 5 cm circle at a point, and an 8 cm circle from another. Make them fairly close so they intersect.
In the 2D scenario we have an approximation of location. If we add a third circle, notice that the area possible has reduced again.
Now repeat for a 4th. You likely can't get any further in on this scale. Imagine this in 3D. That's a simple model of GPS.
In our case the little area segment formed by the intersections defines the accuracy. I don't know if the device does it this full way or if it presumes X locked satellites is Y m, but you get the idea. Remember gps is 3D though, so height is involved. But this is a simplification and I believe the approximation uses a simplification too...
Tbh you should try going along a known route, tracking your path on a gps logger. Put it into Google maps and see if it deviates from your route.
Use a dumb logger application that just records NMEA packets though, to stop it using maps to "guess" location to a road.
That help?
OP is probably trolling. I tested this whilst driving and not only did it track accurately it tracked my speed accurately as well. Here is the my track to prove the point:

Didn't use WiFi or sensor aiding, that's pure GPS.
I am absolutely gutted, having read what I thought was good GPS accuracy. I have made a track tonight just to test, and I am very disappointed with the result.
At one stage it shows me on the other side of a road which I did not even walk on.
Here is the link for you guys to look at, what are you thoughts on its accuracy.

Maybe I am misunderstanding here, but isn't it pretty normal for phone GPS to be a bit inaccurate at times when used in a city? I know there are certain areas in my city (Vienna) where, when I'm walking about on the sidewalk, my Nexus One can't locate me on the map or at leasts is very inaccurate at it. Especially narrow streets with tall buildings block the GPS signal, but even on wider avenues my Nexus One often isn't absolutely accurate (but precise enough).
Unfortunately, I don't own a Galaxy S2 yet, so I can't provide any findings of my own.

So I take it you're claiming you weren't drunk, despite the clear evidence?
Can you tell us what GPS Test shows for accuracy when you use it outside? Also, how stable is it, does it fluctuate more than a few meters once it reaches it's best level?
Thanks very much for posting the track.

I get the same on my SGS2.
ALSO i think related to this is that i am getting no little blue circle on google maps showing the error.. is everyone else seeing this or do some of us just have defective phones/software..
strangely enough the accuracy eventually goes down. even after the long lock time and the navigation is fine.. all the way to work now tested with aura and google maps and not a narry wrong info..
Yes its not good just check out this video of the SGS Vs SGSII in GPS and it fails!!!
Real bad..I hope there is a fix for this. But this is the second time now!!! Samsung jsut don;t learn. The Omnia HD i8910 has amazing gps this is not acceptable!
I really don't seem to have any issues with my GPS accuracy, it locks my position quickly and has fairly good accuracy, heck it performs better indoors than my Milestone did.
I must have a faulty GPS sensor then? Time to post the phone back
Edit: look at my SGS Vs my SGSII . No vop or dvop data on the SGS2
I've been out Geocaching with my milestone and SGS2 side by side and there is no difference in the distances on the radar.....
I took a drive from south ready london to west without a hiccup. app or firmware specific? mine is ....D

This test must not be done because the electromagnetic field of internal oscilators make interference with the other. If you put the galaxy's far each other you will get better results and similar. I made exactly the same test about 50cm distance between the two and got good results.

what the video didnt show you!
did you check all THREE?
check on "use wireless network", check on "use gps satellites", check on "use sensor aiding"
i tested gps driving 60 miles, gps locks on quick, never lose gps signals or give me wrong turns.
tested gps from work to home, gps locks on quick, never lose gps signals or give wrong turns.
sat in my house just on gps it takes 15/20 secs to lock on....but then again my phone signal is very poor in the house, and when I am in the city its about 5 ses and works 100%

Yes all three location options were ticketed. It never got a signal otherwise the video would have been 5 minutes long or more. It was random but now all is well after a reboot. I think we are relying to much on GPS Test. It may not support the GPS chipset in the SGS2 100%. GPS Status seems better..
I found that when I was moving in the car it was more accurate. Infact down to 4m. It sat at around 4-10m the whole trip with 8-10 sats. I couldn't have asked for better.
Oh and here is my proof:

However it depends on frequencies and harmonics that GPS phones switch/create in that moment.
There is no perfect shield. Do you want a proof? Go with your phone inside a compartment in a metallic ship and then it's possible to call you from another city. I'm sure because I made this test.
I assure you that in my SGS1 and my SGS2, GPS doesn't work well if they are close each other.
OK, but what about the dop and vdop calculations on the gps status application?
I would say the app doesn't support read that info yet..
i dont think that is it try google maps there will be no little blue circle meaning i believe that the phone is not providing that info..
Strangely enough, but mine provides the blue circle in g maps, and no data in the dop and vdop calculations on the gps status application.

weird mine has no blue circle but is right on during nav. in google maps but takes a long time to lock.
Well, damn it ASUS! I had a vague GPS thing going on when I first got ICS. Since I got the update for GPS it's killed it
I left the prime in the window bay for 25 mins and this is what I got

Nothing. I presume this has nothing to do with root etc? Would a system erase make any difference? Is it even worth a try?
It's not like I use it often, but it used to lock from here fine and now it doesn't.
Meh!
No difference for me, no satellites before or after the update. But...

You should get some satellites if you turn the device around. Right now the metal back possibly blocks all potential signals. Aluminum back cuts down about 50% of GPS signal performance compared to smartphone like Galaxy Nexus (which also does not have ideal GPS, though does work).

Good idea and thanks - I tried this, flat, next to a window and left for an hour. Still nothing How can an OTA update that claims to fix GPS break it?! Lol!
Yeah, I got the same - absolutely nothing despite over an hour face up completely flat.
My phone (Dell Streak) gets locks immediately in the same place.
The only way I've managed to "see" a single satellite on my Prime is after BT tethering to my Streak!
Very disappointing, not that it's crucial to have GPS, but there's a principle involved here.

Do yourself a favor change the power modes while in the GPS app!
See that little circle notification if it is not flashing it is not trying to lock so all you gotta do to get it to start locking is expand than minimize the notification bar!

Couldn't agree more. I had mine picking up sats in my car with Honeycomb...then ICS came along (second ICS OTA) and decided to take it away from me. Disappointed. Now, where's that Mr.Gary Key? Ha!
Ditto - this last update killed my previously acceptable GPS performance. Mine will see as many as 8 birds with decent SNR, but will not lock on any of them.

Ooops I should have multiquoted! Anyway, clearly it's happened quite a lot....gutted.....
Wow guys, this sounds really bad. I thought that the flaw is simply that the signal is weaker by half (as it is on my tests), but apparently it doesn't get any locks at all for some of you.
This is definitely not a metal casing problem, GPS antennae seems messed up. GPS, by design, should get some locks after just a few minutes, no more than 10 or 15 minutes.
All of my tests show the flaw of metal casing weakening the GPS signal, but it still finds satellites (though cannot be used for navi as a result) without WiFi.
Try going to some open space and hold the tablet skyward and see if there's any change. Indoors is not an ideal testing condition (depends on where you live), because it still might be the metal-back issue.
It not purely a hardware issue though as my GPS was on par with my cellphone before this last update.
I am also getting no gps lock in gps test since the last update. I got my prime to lock onto about 15 satellites prior to the update driving in my car(its a convertible) Now I can't get it to see a single one, let alone get a lock. I love my prime, but this is a real bummer.
I agree....if this was a pure hardware related issue, then it wouldn't have worked before then suddenly stopped working post drivers/software update. This clearly highlights that there is a software related issue going on. Obviously the aluminium backplate still reduces from the overall signal quality but it don't completely prevent it from working. If this was the case, no one would get a lock ever, on any unit!
Your move Asus...
Likewise. Signal before update. No sats found following update.
Same problem here. I did not originally have an advanced GPS app or anything, but services were able to locate me in GPS (when Wifi and location via Wifi turned off). Since the update, I get nothing. I download several apps to test GPS and all are the same: No Sats.
I don't really use GPS all that much, but I tested this before installing the update and the update did definitely break it for me.
Seems like the update was 50/50. Either it makes everything brilliant or just takes it away!! How do we approach this best? We can all contact ASUS individually but that never seems to work. I wonder if Gary Key accepts PM's?

LOL, I couldn't resist.
I believe 100% that GPS is a Software/Firmware issue. I also know that there have been threads about this before.
That being said I had GPS working fine on my tablet when I got it and performance has gone down with every update. I am now on .14 and I have no GPS at all. Inside, outside, vertical, horizontal, with a phone, without, clear skys, rain, etc. The only 2 things that I haven't tried is taking off the back of the tablet and using gps tether, reason being that it worked before and now it doesn't and tethering has nothing to do with the internal GPS.
I'm almost thinking that they disabled the GPS in one of the last updates 13 and 14 for sure.
EDIT: What do you know it must be like going to the doctor. It hurts until you go there then everything is fine again.
My Prime is seeing 4 satellites in view right now however the gps has not "locked" yet.
The weirdest thing is that I left GPS on for a couple of hours with the screen sleep turned off and got nothing and now in the time that it took to edit this I got some satellites in view. I'm at a loss.
Has anyone else had similar experiences?
@Gary Key any input on this? Other than GPS my tablet is 100% functional, I haven't experienced any of the other problems wifi, reboots, etc.
it is hardware, it's been proven. the GPS and wi-fi antennas are connected via pogo pins and in some primes te pogo pins are touching, giving you great performance and in others they are not touching giving you no GPS.
GPS works on mine with .14, but doesn't lock to as many satellites as with .11, nor does it maintain as consistent a signal.
Personally, I believe the GPS issues are a combination of hardware and software.

I don't buy the pogo pin theory. However the aluminum back might have something to do with it.
And how exactly has this been proven? Not to start a flame war but nobody has replaced the pogo pins with solder and put the prime back together. They have only added antennas to the device and/or removed the back plate. Lets get with the scientific method here. Change one variable at a time.
In my case the only thing that has changed is the version of the software on the tablet. The newer the software/firmware the worse the performance.

There's a multipage thread about this already (GPS performance acceptable, then degrades after .13 or .14 updates). Here's what's going to happen: You'll probably get flamed, a bunch of people will insinuate that you're an idiot for even SUGGESTING that it's not completely a hardware issue, and a few will mock your methods as unscientific. Debate may or may not go back and forth for a while, and then the thread will slowly die. And one day, .15 or .16 will come out, and maybe your GPS reception will magically improve again. Who knows?
I don't think that GPS will ever be GREAT (lots of birds with green-bar signal strength) but I do think that software updates are effecting the ACCEPTABLE GPS that a number of these units seem capable of achieving.

This has been pretty extensively discussed in this thread:
http://forum.xda-developers.com/showthread.php?t=1474391
The aluminum case is definitely a major problem for GPS and Erusman "solved" that problem by attaching external antennae to his Prime so that the GPS can get a relatively clear signal. He experimented with several different types of internal antennae, hard wired the GPS antennae to replace the Pogo Pins, etc all with very poor GPS results until he ran an antennae out the back of his Prime.
To me (and most people who followed Erusman's testing), this indicates that the GPS's main problem is a hardware one, that hardware being the aluminum backplate of the Prime.
I have had varying GPS performance with the different firmware updates, which indicates that software can be a factor. However since I have also had generally poor GPS performance regardless of which formware I have been running I am pretty sure that software isn't as much of a factor as encasing the GPS antennae in what amounts to an aluminum faraday cage .
Not another one of these. I posted this on another forum. To the OP, if this is software please explain my results. Now even though it was picking satellites it wasnt really that useful as it didnt really track me on the spot when doing turn by turn.

I pretty much agree. I doubt it will ever be truly accptable to the level of say, a TF101 - though I was told that my replacement C1 Serial Number Prime would be "At LEAST as good as a TF101" by a tech support manager. Seems that where the Prime is concerned NOTHING is a "given" Some days I get some GPS activity, some days not so much. What is apparent with my current unit is, GPS is EXTREMELY inconsistent, and not just from session to session, I mean from minute to minute. I can have 11 sats in view, using 5, and 10 seconds later lose half of them,or ALL of them, all without even moving the Prime so much as a millimeter.
I guess I will never be able to use my Prime as a "professional GPS device" Or as an unprofessional GPS device, or as a GPS device of any type. Sucks... and will continue to irk me for as long as I have and use a Prime. Probably for a long time after as well. I suspect that any mention or thought of Asus will no doubt bring the Now you see it, Now you don't GPS screw up to mind.
Know what would be great? Not having to see ONE MORE comment like "I didn't need the GPS anyway" or the classic: "If I want GPS, that's what my phone is for." That's terrific! Then if you buy a new car and the $1800 Navigation doesn't work, and the manufacturer decides to just stop supporting navigation in that model, you will be all set with your phone.
Don't TELL me how a tablet doesn't NEED GPS, and don't TELL me that the iPAD 2 WiFi doesn't HAVE GPS. I didn't BUY an iPAD 2. I bought a device that said "GPS" on the box and on the web. My GPS doesn't even work for LOCATION, never mind navigation.
Tell me again how I can just return it if I don't like it. That's the Problem... I do LIKE IT... I FREAKING LOVE IT, all the more reason why I want it to work properly. And I don't want to return it, I want to exchange it, or fix it. If it will never work, well, then I will never be completely happy, but that doesn't mean I can go get one of the many "Comparable" devices (Like Best Buy offered me when the oversold Pre-orders. There ARE no Comparable devices.
SO I am stuck using an add-on Bluetooth GPS Tethering device. Works ok. Bug me that there is GPS hardware right here in the Prime that doesn't work. Bugs me a lot. I am an engineer. Crap that doesn't work, or works poorly bugs me.
It's like the "Real Feel" weather people. Telling me that it's 60 degrees, but "feels like" 63. Not to ME! To ME, it feels like 66. Don't TELL me how to FEEL!
No one can tell me how to feel about this either. It feels like I got ripped off. Rant over (for today)
I think its the software too.
I was sent a c model that works perfectly in every way except the gps which will not lock on to any sats. BUT using free nav usa I can lock on to sats and stay connected. IT IS NO GOOGLE MAPS BUT it does work. Sooooo is it software ?
Ok, so I'm only marginally tech savvy, but lets say i wanted to set up optimal GPS conditions for my prime (which has never seen a satellite). How would I do that and what programs do you recommend.
So far I've tried putting my prime next to a window running GPS Test and letting it sit there for uo to 10mins.
Thanks
@SmartAs$Phone:
I know exactly how you feel. My prime's box didn't have GPS listed, and I was aware of the issues going in, so to me I knew ahead of time and I was okay with that. Bestbuy, on the other hand, was still advertising GPS as a feature at the time (End of January) and last I checked on their site they're still advertising it.
But for the folks that bought thinking "Yes! Full on GPS!" and it didn't deliver I can certainly understand the frustration. Double so, considering that when it didn't work they came here and found many others with the same problem, and they realized that had the done more searching up front they would have known about the issue.
In the end, however, no software is going to fix this problem as has been proven by the various hardware mod threads. For those willing to mod, that's a fine solution. For those not willing to mod, well, I don't know what the solution is.
Well, my C1 model had relatively OK GPS with .11
At my front door I could get 11 sats and four locked and it said about 48 feet accurate. BUT, use maps and my location jumped around and was typically 200 yards or more off.
With .14, I get a lot more sats, more locked, and 36 feet accurate. And on maps is locks dead on to where I am.
Can firmware improve GPS? Clearly. Did it get better from .11 to .14? Clearly.
Now the good part. If I was lucky I got a few sats intermittently indoors (1 to 3) after a few minutes. NOW, I get 7 sats and a lock with 72 feet accurate, and the map is about 100 feet off, but on the right street.
Say what you will. I don't have anything special. Same metal back.

Seems like I pretty much called this one.
I am also thinking that gps issue is mostly software problem. When I bought tfp there was android hc. I had seen 15 sats and connected to 13. Whith .11 it dropped to max 6 visible but I was able to get a fix. Now with .14 I can see max 4 sats with no fix. I`ve got no problems with reboots nor wifi.

I agree with you 100% I'm an Avionics Tech I work with GPS rx's all day. We have a GPS generator and with the unit right under the gen it shows about the right -dbm however is unable to obtain a constant lock. If I pad the signal down it gets better and locks on solid. IMO its an AGC problem which is a software setting for this chipset. I have been temped to open my prime up and solder smb connectors to the main board and hook it up to a good GPS antenna, but I know it still wont work. People here dont seem to understand RF and how antenna's are a specific length ect. I'm not bashing people but a clip lead isn't an antenna nor a valid test.
I am having the exact same problem. At times I get no love, no birds, like right now. Zippo, nada, But last time I checked, I was getting lots of satellites. Very inconsistent and I can't find any reason for it..

In case you didn't know, the Note can use GLONASS instead of GPS (Click on the words to read more).
People use GPS like "Xerox", "Coke", or "Kleenex"... but nevermind that.
What is your GPS/GLONASS lock time with A.GPS (Assisted GPS (network location)) and sensor aid on??
Please describe whether you are outside or inside. I am also particularly interested the lock time from a fresh boot or if you're using GPS from a new location.
IMPORTANT: Please note (excuse the pun) down, when you launch Maps or Nav and the arrow shows up almost instantaneously, I would like to know IF *sometimes* the GPS reticle on the status bar continues to flash/blink for a while.
Why do I ask? My Note takes anywhere from 3-12 seconds to lock when GPS is "hot" and takes 10-25 seconds to lock from a reboot in doors while stationary.
Compared to my Sprint Evo 3D, GSM Galaxy Nexus, or the iPhone4s that I never use, that is slow. When I powered up the Galaxy Nexus for the first time, it locked under 5 seconds! My Evo 3D would lock from a boot in under 5 seconds. The 4s is super fast also. The Note, with GLONASS, is supposed to be faster and more accurate...
Thanks.
Edit: Interesting discovery today--the slow lock and low precision in my car may be because of my car--but it may also be revealing limitations in GLONASS:
Every piece of glass on my car is double-paned (twice as thick as the typical car glass), sandwiched with a polymer layer, along with an IR rejecting coating. This is designed to keep the interior very quiet, makes the glass theft resistant, and the IR coating reduces the heat that enters the cabin (heat travels in the form of infrared). The IR coating, unfortunately, also rejects other radio frequencies in the electromagnetic spectrum. That, along with metallic particularized tint, causes a reduced radio performance for any device that is in the interior of the vehicle.
I usually don't have any problems with the GSM/UMTS or CDMA phones, and GPS has no problems either (although I notice a reduced s/n ratio). As I indicated before, other GPS-based phones lock fine, and the GPS+GLONASS iPhone works fine also.
As I was driving home today, I tried opening the window. I noticed that every time I opened, the phone would get a quick and solid lock. Every time I closed, the uncertainty circle appears.
Is it possible that GLONASS, operating at 1.6Ghz, using FDMA is less able to penetrate certain objects than GPS operating at 1.57Ghz using CDMA? I presume civilians are still only using the coarse channels so that doesn't help. It is interesting to see that GPS have no problems in my car while GLONASS does. I will drive another car tomorrow and see if there is a difference.
My Note locked within 2 seconds this morning, on my way to work. I was outside in my car.
When opening google maps, I get a lock before the app is fully open, ie. I'm already locked by the time I can do anything in the app even. Compared to my Captivate and Infuse, the lock times on my Note are godly.

I lock before apps load that can use it such as maps/nav. I came from a Vibrant that even after numerous "fixes" it still could take a couple minutes to lock.
Wow... That is what I expected from my phone. Are you guys all using the stock ROM? If not, what ROM are you using and who is your carrier?

A follow up to those who responded:

Thanks for the information.
I was excited for the GPS capabilities in this phone before I bought it, but my experiences have been far worse than everyone elses. Google Maps is loaded for about 5 seconds before it even STARTS trying to acquire a position. And even then, while indoors it takes a good 20 seconds to lock on. My iPhone 4 locks on indoors in about 3-5 seconds.
With the note, many apps think I'm 10-15 miles away while indoors. Especially with weather apps that just want a quick location fix but don't leave the GPS on during use. At first glance everything thinks I'm far away. Chat apps that only use GPS when sending a message have the same problem. Navigation apps that leave the GPS on during use are accurate. It's annoying. Never had an issue like that on my old phone.
Outside though, the Note seems to lock on nice and quick, within about 2-3 seconds upon starting acquisition, and my accuracy is generally at 3 meters or less. Even my $650 handheld GPSr doesn't have that level of accuracy.
EDIT: The notification bar icon DOES continue to blink for several seconds after achieving a lock.

As for accuracy, this is a function of the number of satilites that you have locked onto. I believe all you need are 2, possibly 3 for accurate elevation, however the more you lock onto the more acurate you are. This is why "quick" on and off checks are rarely very accurate. however, with weather, the phone grabs your location and then queries the closest whether center, which is very rarely in your neighborhood. Typically it's your closest airport or military base, so this will atleast be 20-30 miles away, but often in same or neighboring zip codes.
For the indoor, thing, I never expect (nor really use) reliable GPS signal indoords. Just because you get a lock doesn't mean it'll be enough locks to do much. I rarely get lost going from my kitchen to the latrine anyways, but I suppose with enough beer it could happen. I would suggest (and you probably already have) check to make sure you make use of "use sensor aiding" option.
If all else fails, I will loan you my vibrant and you can experience a man-tantrum in your car when the fking thing wont lock after 5 minutes and your lost as **** and late as hell and google maps keeps freezing and FCing. That'll make you want to wine and dine your other devices for treating you so well.

I believe you need at least 3 for triangulation (location) and 4th to give elevation.
Another interesting thing I noticed about my Note--even if it locks quickly while I am stationary, it looses lock when I am moving (driving). I had my Sprint Evo 3D, Verizon Galaxy Nexus, Sprint Galaxy S Epic 4G, GSM Galaxy Nexus, and the Note side-by-side on the dash. The only phone that keeps losing and reacquiring the lock the the Note (especially while traveling at freeway speeds).
my note locks on really fast
under 10 seconds for sure.
If im out side its within 5 seconds.
My Skyrocket usually locked in around 10-15 seconds
my inspire....30 seconds.
my nav in the car....30 sec

Very useful tool. In addition to that one, I also use GPS Test, GPS Essentials, and GPS Status. Each brings something different to the party.

Sounds like you need "Kick GPS - The 12 Step Program"
Really? Your complaining about 12 seconds to a gps lock? (regarding the OP)
Give me a break...
My DEDICATED GPS Tomtom unit takes over 2 minutes to get a lock, I consider it a blessing that my phone locks faster than a dedicated gps.
Good Lord...
My guess is you are one of those that complain about your browser taking more than 2 seconds to load as well.
Regarding gps stability, there are a couple of different things to try, namely one of the more rare things is calibrating the compass. There are many videos on Youtube, just search 'smart phone calibrate compass'. You'll find 3-4 different methods, any will likely work. And yes, the compass does affect the gps keeping a lock in speeds higher than 20 mph.
Another thing to try is downloading the latest gps satellite data. There are several apps available on the market that can do this (GPS Test, GPS Essentials, and GPS Status all do this).

Why so excitable and quick to judge? "Give me a break..."? "Good Lord..."? Really?
Your TomTom uses GPS, not GLONASS and does not have Assisted GPS. GLONASS and A.GPS should allow a faster fix. With these new and additional technologies, the phone SHOULD get a much faster fix than your TomTom. You're comparing apples and oranges.
My Evo 3D, Galaxy Nexus, and other phones I metioned, with GPS (no GLONASS) and A.GPS will almost ALWAYS get a fix in 2-5 seconds. If enough research is done here at XDA, you will find that many newer devices, if working properly, *should* get a lock in under ten seconds. Your "DEDICATED GPS Tomtom" [sic] is a different and arguably less advanced animal.
Another example--the built-in GPS in my two vehicles lock IMMEDIATELY when the car is on. Why? Because they remember the last location, use brake sensors, steering angle sensors, and accelerometers to determine location. If they do not lock immediately, something is wrong.
If you re-read my original post--I am trying to figure out if others have the same problem, and attempting to understand what others are experiencing. At the same time, I provided information on GLONASS, in case other owners didn't know they had it.
For a just-released, $650 device, I expected mine to perform on-par with other phones. Perhaps mine is defective? I wanted to find out if I need a replacement. Last checked, this forum is about people asking questions, sharing information, and learning something. To that end, I am puzzled at your comments--it seems like *you're* the one who is complaining...
So yes, really!

Yes, I suppose...
While I'm her--there is also F GPS (fake GPS, provides coordinate of your choice to the location manager), GPS to MMS (allows you to send a text/MMS with your current coordinates), and GPS Speedo (a nice GPS-based speedometer).
See the edited OP. I made an interesting observation today. It seems like GLONASS signals are less able to penetrate objects...
My Note's GPS performance is flawless and is my most loved feature of the device. Superquick and very accurate.
I use the GPS all the time for backpacking, motorcycling, running and of course general finding all the stores my wife makes me take her shopping on the weekend.
Even better than my previous iPhone 4 and 3g.
My Samsung Infuse's GPS was a disaster taking forever getting a lock, loosing it, placing on the next road over, and not performing if sitting in the middle of my car...constant frustration so I REALLY am happy with my stock Notes GPS.
