[Q] GPS Tracking Accuracy Poor - Verizon HTC Droid Incredible 4G LTE

I have been having GPS accuracy problems with my Verizon HTC Incredible 4G LTE for a month and a half. It does not accurately measure distances using tracking apps such as Runkeeper. I have used Runkeeper for over 2 years including 2 years with my original Incredible first generation and the measurement was ALWAYS accurate. I upgraded to the Incredible 4G the last week of February 2013. A month later, the GPS began inaccurate tracking (it was accurate for the first month). I tried other tracking programs such as MapMyRun and they were also inaccurate. Using Google Maps, the accuracy is reported within 3 meters usually. Verizon reluctantly agreed to send me a new (reconditioned) phone and which I have had for almost a month. Of the 20 runs I have done with it, only one tracked accurately. Not sure why as the settings were the same as the run before and the run after which were both inaccurate. I have tried 5 different run tracking apps including Garmin Fit which does not use Google Maps. All are inaccurate. Runkeeper is the closest to actual and it varies anywhere from 1/10 of a mile off on a 3 mile course to as much as 8/10 miles off on a 4 mile course.
A jpg of today’s run is attached as an illustration. The red track is my Garmin 205 Forerunner, the yellow track is Runkeeper on the Increbible 4G. Total distance was 3.07 miles, Runkeeper measured it at 3.29 miles. The variance does not look that significant in the pic, but .22 miles over a 3 mile course is very significant and, again, on my old Incredible, it never varied by more than .02 miles from my Garmin (which I would rather not use). It looks like the signal is drifting by 40’ to 50’ and then coming back. Using GPS Status, the number of locked satellites and accuracy does not vary much at all, not more than 13 ft.
I have searched the web high and low and tried every suggestion I can find including using the GPS Status app to reset the AGPS cache, clearing app caches, phone caches, wifi on, wifi off, GPS only location setting, no antivirus, no battery saver, screen on all the time, just everything I have seen recommended. I have talked to Verizon and HTC. Nobody can solve the problem and I don’t see anybody else posting problems with the Incredible 4G LTE GPS accuracy. I am convinced there is some kind of interference between the actual GPS and the communication with GPS tracking apps. I am not even 3 months into this contract and I hate this phone. Can anybody help?

Do you have Google location service enabled? I noticed apps not getting accurate gps when I had it enabled for Google now...

That would be interesting - it could be a power-saving measure to use Google location over GPS when a certain degree of accuracy is possible (a degree which is not agreed upon by all).

I have tried it with both Verizon and Google location disabled and tracking is still inaccurate. I don't believe I have tried it with Verizon on, Google off, but I will do so on my next run...I am willing to try anything.

Do you still have your original Incredible? You can still use its GPS to track yourself even if that phone isn't on contract with the network.
Another possibility is flashing the old radio from the original stock ROM from when the phone initially launched with Android 4.0.3. I am using that radio and have never had a problem with GPS accuracy. You'd have to S-OFF your phone to flash it, but it's definitely worth looking into.

Okay, so I tried it with only Google location off...no difference. Tracking was off .26 miles over a 4.23 mile route. I also tried it with wifi off, Verizon and Google off, Google maps running, screen not allowed to sleep and tracking was off .15 miles over a 4 mile course.

No, I don't still have my original Incredible. I wouldn't want to do that anyway because the main reason I like to use the phone apps to track is that the data is sent to the website (Runkeeper) and I have access to all kinds of statistics. That all happens in the background which is nice. I can upload data from my Garmin watch, but it is not automatic.
I am interested in trying flashing the old radio, but don't know how to do that. Does the phone have to be rooted? Would it void my warranty (I haven't given up the idea that Verizon or HTC may replace the phone)

You have to be S-OFF, which doesn't necessarily mean you have to have a rooted ROM. Going S-OFF would void your warranty if you sent it in that way. You would have to flash an RUU and re-lock before sending it in. Also, if you S-OFF your phone, you will lose everything that's not backed up: contacts, game data, everything, so be sure to back everything up.
You can obtain the old radio here, and instructions for flashing it are simple once you do that. Download the radio, install HTC drivers and ADB, reboot to Fastboot on your phone (Turn off, hold down button and power on device, go to Fastboot), in ADB, type "fastboot flash radio [radioname].zip" ([radioname] being whatever the filename is before the extension), and run that command a few times to make sure the radio sticks. Voila, different radio.

How good is your GPS working?

So I went out and used my GPS for the first road test. After turing on iGuidance i got a fix very quickly and it saw me...but then it was horrible in updating. I would start driving and sometimes it wouldnt even move for 30 seconds. the accuracy was not there either. With my ext GPS it would tell me I was a few feet from an intersection, now im lucky if im near it. I was getting 6-10/10 sats also, so very good. maybe the software? So what are everyone else's driving experiences and with what software? I dont have data so i cant use gmaps/live.
i just had google maps up and drove to the store this morning and it followed me very well....
then it followed me around the golf course almost exactly on the edge of the greens maybe 1-2 feet off at worst
My GPS sucks too. I have used googlemaps and geoscout(which I think actually works better than googlemaps) I am off by about 25 feet in a random direction with googlemaps using satellite maps. I too have 6-10 satellites.
Anyone have a cab for TrackyPro v3.0? I hear that that is really good especially for off roading.
google maps seems very accurate to me. also last night i was out of town and used the sprint navigator to find parking very easily. we were moving slowly, but i would estimate it had us within 10 foot.
It's been working great for me. I tried it out last night while on a quick drive and it tracked me the whole way which about 5 satellites much of the way. It was only a few feet off the entire time.
my google maps is accurate to within about 5-10 feet, i was in line at the mcdonalds drive through last night and for kicks i brough tup the satellite picture and watched my dot get closer to the window, lol
My gps is working better now. This is how I fixed it. First I relocked my phone. Then I upgraded to the original leaked version of 2.16.651.0 and let it do it's thing. DO NOT USE A MODIFIED 2.4/2.5 BOOTLOADER!!! For some reason the gps is of by about 20 feet when using the modified/hacked bootloader and is almost exact when using the original. The original is also much faster not only with gps but in genreal.

no offense, but this is completely false. the bootloader has no effect whatsoever on gps performance.
That may be true but for some reason that is what I have noticed. I have not changed any other settings either. Oh and dcd since you are here are you planning on releasing a kitchen for the new gps rom?
Used TomTom on the way home from a Sprint store and the thing followed me the whole way. Told me to turn the split second I got in front of the driveway. I am liking the added feature very much. Only complaint is why do I have to turn on google maps to get the GPS to work?

the GPS has to be initialized before it can be used, and some apps (like tomtom) dont do that
theres a thread on ppcgeeks about it, the OP recommends using maction (?) GPSViewer to initialize since i guess its faster than googlemaps
Google maps and Live Search work very well for me. Pretty much spot on.
I drove around today and tested it out. Followed me perfectly on the roads. No hicup of path....just chugged along right where I was....both in Google Maps and Live Search....Altho L.S. is cool because it shows the arrow...
My connections somtimes won't connect....like I've noticed it seemed slightly buggy...maybe just me....but if it does something weird...a soft reset DEF fixes it.
DCD.....YOU ROCK MY FACE! THANX!
PS...
This was my first ROM flash ever....I thought I was unpacking the BootLoader to my PC before I wanted to actually start...I hadn't read anything, and it installed on my phone and before I knew it I was staring at the multicolor bootloader screen.....F*%K! Long story short...I figured it all out with these forums and so THANKS!

I have had good luck with tom tom navigator as well. I too have the problem with having to have another program initialize the gps,but I understand there are people working on it.
Mine worked well all weekend. Using Google Maps it followed me all around town. Same as a previous posted for grins i pulled it up in a drive through and it tracked me slowly moving up in line. One or two hiccups but nothing earth shattering.
GPS works great
mine with googlemaps will update itself every second it looks like. tried it while driving around San Diego, it was spot on the whole time. if you turn on Field Trial when you're running a GPS app, then look at the GPS stats it will even show you your horizontal speed in meters/second. tried that while driving around too...seemed to be right on the money. have anywhere from 4 to 8 satellites most the time. at work right now in La Jolla, I've got 4 inside the building.
I'm having a similar issue with iGuidance and sent an email to my contact at iNav to see if there is a known issue.

Thanks. I found the app when I was looking around today and installed it. It does work well. Click it, it opens up the GPS then opens TomTom(or whatever program you want it to open).

GPS
Mine works like a hot damn.
Mobo
I took my boat out today and used it... thing was SPOT ON using gmaps! I stopped at a few islands and walked around and it tracked me all the way and it was exactly where the satellite pic said I was.
Sometimes I noticed in my car that if its not close to a window it will only get like 2 sats and the position wont be all that great. I have GPS built in my car, so its not a big deal.

[Q] GPS software?

hello there...
is there any gps software that compatible with my sgs2 that running without any data charge?i mean it just using my gps,not gprs other than google maps because it suck a lot..
there are a few out on the market some are free. others you buy. These programs use internal maps and gps, no data.
igo, tomtom to name a ew which are compatible with android phones.

These phones don't seriously have an internal GPS antenna; do they? If I turn my data signal off I get no GPS.
How does the GPS work exactly in these phones? I mean with data on I guess it somehow uses tower triangulation to find the phone...but how does it work with the data network dis-activated? I'm confused.
The phone has full gps chip and aerials, with the data connection off agps won't work so well, and google maps won't work, but anything that stores there maps locally will work.
GPS fix will take longer without agps

So without data it will still get a lock? You're saying that the phone DOES have a GPS antenna inside?
I've tried it before and it just seems like it searches for satellites forever and never gets a lock.

Wow, ofcourse it has a GPS antenna
It does take some time to lock for the first time (like 2 minutes), but it works well.

Yes it does, but a cold lock with no data connection will take quite a while.
Also make sure you have a clear view of the sky.

So why does it take so long to get a lock compared to lets say a regular GPS unit that you put in your car? Is it because the antenna is smaller?

It should take the same amount of time in most cases. But sometimes the circumstances are different. A typical fix time i 5-30seconds for my SGS2, but sometimes it is slower.
And if your chip for some reason needs a complete configuration from the satellites it could take up to 10-15 minutes to get a fix (exceptional situation).

With data off and corrupt calendar data in the GPS chip it takes even more than 5 minutes.
Wait 15 minutes instead. This time is required due to the extremely low bit rate from gps satellites (50 bits/s).
Another idea is to download gps test from market and clear and update agps-data, this requires data connection on.
Both these solutions are known to work for others, hopefully one of them works for you.

@cosmic blue:
warez link reported!
also, to clarify a few things here:
there is no tomtom for android.
basically, there is igo, navigon and ndrive.
these are offline navigation apps that do not require a data connection for navigation, since their maps, pois, voices... are stored on the phone itself, BUT navigon for instance, requires a short server connection to verify your version is legit. i don't know about the other two though.

Thanks I'll have to try that.
Basically what I want to know is that if I'm out the cell signal area AKA no cell signal and no data (obviously), the phone will still be able to get a lock? If so, that's crazy! I didn't know...I thought it either got your position from the net or triangulated your position via cell towers...not actually receiving data from a GPS satellite.
I used sygic when in spain it was really good no need to data

GPS Problem? But is there really?

Hi all
Theres alot of talk about GPS problems with this device.
Im a Navigational Officer with a marine survey company and GPS troubleshooting is in my day to day line of work.
The biggest problem i have with new units is well theyre built in Asia and then these units get shipped over to the USA and Europe. So when they first get turned on they are expecting a satalitte geometry for Asia.
These means it can take a long long time for devices to get a lock. Once it gets it though future times you use the device should be nice and quick an easy. Now the equimpment im using is completely different to the Tranformer Prime but the stuff i use is worth millions of millions of dollars. So its safe to say if it can take up to several hours for a first time lock to occure with a million dollar piece of gps equipment how long will it take for a tablet? Most of the time i have to reprogram the card and tell it its at a certain lat long this reduces first time start up to maybe 40-50 minutes before it gets a good strong signal. So bare that in mind when your saying GPS isnt working with the device have you really tested it?
Now i dont have my Transformer Prime yet ( preordered through amazon uk) and when i do there will be a extensive test done on wifi and GPS and some tweaking to improve them best i can. But here are some suggestions you might consider.
1. WIFI - yes turn your wifi . Yes i know this sounds stupid but it helps the tablet find itself that first time it tells it ohh im in this country and i need to look for this. Do this several times then turn your Wifi off and try GPS on its own.
2. Leave it alone - I know its hard to do but just turn your GPS on and then just leave it dont move it touch it play with it. Just let it find itself and the satalittes. After finding itself a few times it will become quicker.
3. Wait for Update - Im in not doubt that a good firmware update will fix this problem in the future even with masking from the aluminium shell of the transformer its still going to be able to get a GPS lock even if its just a handfull of sats and technially you only need 4. With a new firmware it will allow the device to find itself a little better. I do it in work all the time reprogram for different regions.
I hope this helps anyone. But the end of the day GPS isnt instant guys. Tom Tom and Garmin have made it look easy the end of the day but thats with the programing of the units in advanced that allows for fast geometry fixes. Just be patient.

Nice summary. I think the amount everyone here has learned about the workings of GPS is college equivelent. But other tablets don't require any priming or special conditions to work. They just do. And that includes Asus' own TF1 and Slider.
Quite true other devices dont have the same problem you are right. But you have to remmber Asus have rushed this tablet out on the Market so to beat the competition. The firmware might not be as up to date as they may like and some nessicary tweaks may need to be in order. Im sure Asus main concern are other areas of the tablet like getting it to power up and run. GPS fixes are more secondary.
I could be wrong and there could be a defect with the tablets ( i hope there arnt any problems) but im hopeing with new updates sat tracking and lock will become much quicker.
While waiting for Prime, I upgraded my OG Droid to Samsung Galaxy Nexus. No GPS issues. And compared the TF Prime to my wife's Samsung 10.1 Tab. No GPS issues.
Couple that with Asus Rep from TF1, and I expected better. Disappointed in GPS perf.

People have tested it with an external Bluetooth receiver and it works well. If it was a general s/w issue I'd imagine it wouldn't. And remember, it's the OS that talks to the GPS chip not s/w that Asus had/has to develop on thier own. The chip itself is made by Broadcom and is similar to what's in the G-Tab and TF1 so there's nothing unique about the Prime compared to other HC devices (GPS wise).
as we speak my tablet was put into airplane mode i did a reboot now it is sitting in my window and running gps test looking for satellite not going to touch until 930 and see if we find anything
Fare enough put in my place hahaha. Well they are only suggestions with what ive observed with other GPS equipment. Truth be told im not familiar with Mobile and Tablet GPS, more of the high end gps surveys stuff. Thanks for the input
Good luck, It may or may not work but just thought id over some ideas for what ive observed in work

fishbowl_00,
Great thinking, but once you get your prime you may have a different line of thought. I've been testing mine for days, using every conceivable configuration imaginable. I've been using GPS since it was released during the LORAN days and have never seen anything this weak!
Mine can usually get a fix outside with a good view of the sky. I even got it to lock on indoors a few times. The problem is it can't hold the lock. Sitting in the same position it will suddenly lose all eight or twelve satellites for no apparent reason and then slowly start searching and maybe finding them again after several minutes. The signals are always marginal. Driving around I can usually get a lock some of the time, if I hold the prime up to the window. Then for no reason it will show me driving out through the forest and then get lost! This is not a one time thing. It happens over and over again.
After several emails to Asus tech, I've been told everything to "it must have a Wi-Fi connection for GPS to work" to "meantime please try to use Google Maps app from the main menu by tapping APPS -> then MAPS icon, please check if your 'current location' is displaying correctly. If not I would suggest to have it exchanged with your place of purchase or you may proceed with a RMA service to have the issue corrected."
Now this morning, Asus has said "Please note that this product is not a professional GPS device and signal performance can be easily influenced by factors including, but not limited to: weather, buildings and your surrounding environment." Never mind that the other tablets and cheap receivers on the market aren't professional GPS devices either, but seem to operate without these problems.
The last straw was when then removed GPS from their specs online this morning on their website. Seems they think that if they pretend it isn't there no one can complain! After all *specifications are subject to change without notice.
Sorry if I sound a little bitter, but I've had it with Asus.
My test airplane mode on, reboot, open gps test, let sit for 30 minutes
Update 1: 10 minutes in we have a really cold prime from sitting in a window on a 20 degree night but we have zero satellites
Update 2: 20 minutes in the prime is now even colder and still zero satellites only 10 minutes left and we will see what happens
Update 3: tablet dropped to 61.7 degrees wow its freeezing but still no lock on gps my test is complete GPS = FAIL

fishbowl_00,
Great thinking, but once you get your prime you may have a different line of thought. I've been testing mine for days, using every conceivable configuration imaginable. I've been using GPS since it was released during the LORAN days and have never seen anything this weak!
Mine can usually get a fix outside with a good view of the sky. I even got it to lock on indoors a few times. The problem is it can't hold the lock.

Tell me about it...
People do not turn on your Wifi to test your GPS its a decoy. When you do this of course it will work because Google maps uses Wifi location as well this would just patch it.
If you really want to test the OP theory of the Asia region that is easy, we need some one with ROOT to download a GPS neuter app from the market. When running you can uninstall the current config and download the GPS data.
I would have done this myself but I do not have root with the firmware I received.
Can someone confirm with ROOT?

Is there somewhere outside it can get a clear view of the southerly sky? It should lock then because other's have gotten it to.

i recommend that u use gps status with wifi turned on to find satellites for the first time. it worked for me. will take 10+ mins. once u get a lock, next time is easier. also try this outdoors in open area and not from window sil

And as soon as your Prime changes location and/or can't access Wi-Fi it will lose lock and not be able to reacquire satellites. For people that only need GPS when they have access to Wi-Fi this really isn't that big an issue. Mapping and navigation while moving (without a wireless signal) is pretty much impossible.

S3 Google Maps / 3D Big Issues

Dear all,
Can anyone tell me if they are able to use Google Maps, especially for Navigation with Satellite Imagery turned on?
I have a terrible issue whereby after about two or three minutes of driving, first, my location freezes on the map (though notable is that the voice commands stay current and correct based on actual location). Then, the screen starts freezing, jumping, jerking, and generally MASSIVELY GLITCHING and flashing in a completely unviewable state. The voice commands however stay correct. It's just as if the device cannot handle 3D rendering of the imagery at all.
Now here's my big issue...
I am now onto my THIRD Galaxy S3, and this issue is reproduce-able 100% of the time, and over 100% of the devices. That is, it does it every time, and it does it on any and every Galaxy S3 I try to use for Google Navigation. And my devices have deliberately been a mix of some White, some Blue, some from one supplier, some from another.
So what I am asking, is are there any users out there that CAN actually use Google Maps Navigation fine on their Galaxy S3...
By that, I mean for a proper period of time, over a proper journey, deviating away from the set route, and with Satellite Imagery layer turned on. EVERY time I do this, on THREE separate devices, the display goes haywire. So I am trying to establish WHERE the fault is... is it phone software... is it phone hardware (I prey not), or is it a Google Maps issue (you'd think they have noticed by now if it doesn't work with the SGS3 though...)
The only saving grace is that it points to a Maps issue, as when using my NatWest Banking App, to locate ATM machines, when dragging the map about, it freezes terrible, then eventually crashes (just as Google Maps natively does for me a lot), and then eventually FC's... and the underlying mapping it uses is, yes, Google Maps.
So I'm after any feedback at all here.
But worried that it's 100% of the time for me, and on no less than THREE Galaxy S3's I've had so far, mix of white and blue, and mix of suppliers and locations...
Any comments please...?
----
EDIT - just to add device info:
Samsung Galaxy S3, UK Unbranded, both blue and white.
Previous Firmware (with the same issue) was: XXLE8. CURRENT FW: XXLF2
Similar behaviour to what I see on the galaxy note after the so called ics update. Everything was fine on GB. So could be an issue with ICS. Because of that, plus a few other critical issues, I'm now an ex Samsung owner.
I have the same issue.
Sent from my GT-I9300 using Tapatalk 2
Try an older version because I'm using v6.1.1 and no problems so far.
I have experienced crazy flashing and also a black screen while using Google Maps Navigation. It occurred about half way through a 30 min journey. I've seen it happen on both my girlfriends S3 and my own. Also, satellite layer was off.
Could be a bug caused by Samsung's graphics drivers? I hope its fixed soon. I'm currently on IMM76D.I9300XXALE8. There has been no OTA update for me yet and I am in Australia.
Well, that's the end of the S3 for me. The GPS using Google maps + Navigation was (is) a major feature for me. It worked so well on the SGN under Gingerbread and totally corked when I upgraded to ICS. Now I see the S3 ships with ICS and you guys have exactly the same issues.
I spoke to my retailer and went into great depth over what went wrong post ICS and they have noted EVERYTHING and has given me a full refund for the phone. This was my fourth device, Samsung cant/wont get it right and I want no more. I have no idea what my choices are for now, I'm using an old motorola clamshell whilst I ponder. I would recommend anyone having issues with the S3 or Note, just send it back to your retailer for a refund. The product is flawed and little will be done until Samsung see devices returned by the lorry load.
I have a white s3 (UK sim free) with lf2 and 6.8.1 Google maps. I've been using Google maps navigation for 2 weeks as my work pda (with built in tomtom) has been returned.
I've used it all day, 5 days a week, making at least 6 journeys per day with no issues.
I tried it today with satellite view and that too works with no issues. Worked ok with shipped firmware too. Le8 I think it was.
I have had the map jump around/flicker before when turning on a layer but exiting and reopening maps sorted that.
Hope this helps

That was not my experience under GB. Under ICS My experience had nothing to do with layers, and reopening maps is not an option when driving, also, that is not how the software should be behaving. So you too have a faulty unit.

I have had similar random bugs on GB and froyo (since my sgs 1) and to say the 1 out of 50 times I use maps it may crash - means my s3 is faulty?
I don't think so
You do realise navigation is still in beta?
Last week Google introduced a bug which killed latitude, few days later another update fixed it.

We both have different experiences. See how you get on with the S3. Personally, I paid top whack for a flagship product and it doesn't work as it should. It also has the faulty eMMC chip. Under GB it never crashed once, under ICS, its so unstable as to not be reliable and not performing as could reasonably be expected. As I say, see how your S3 goes. I'm certain that not all units will display the same characteristics, but its clear some are. ;-)

Thanks, wasn't aware the eMMC chip issue was present in the s3, I'm sure I ran chainfires app to check when I first got it.
I shall bear that in mind when flashing, seeing as my s2 died a horrible death because of it

Firstly, a BIG thank you to ALL who have contributed to this thread.
Could I ask that those with issues though, tick the poll to say so, as the comments in the thread indicate lots are seeing this issue, but the poll indicates most are having no issue.
Just to add to my own original post though, to say that today, on two separate journeys, Google Maps Navigation worked FINE for me, but with the SATELLITE LAYER TURNED OFF.
That is, standard mapping, and I had no screen issues.
So this only seems to happen when Satellite Imagery Layer is turned ON. In which case it does this 100% of the time for me, across 100% of three different S3's so far, and let me be clear, is so bad, the application is 100% unusable (unless you navigate by voice prompt) as the screen is either entirely frozen, or glitching permanently and incessantly, the whole time.
So my next question though is this... if this IS only a Google Maps Software issue, how exactly do we reach out to Google, to tell them that GMaps is not working, with the latest flagship Android Device...?
Also, as best I recall, I never had this issue with GMaps on my SGS2's both running ICS. But it might have been an earlier GMaps version.
Now, how would I find an earlier GMaps version, to see if that works...?
(Finally, as an aside, why does the SGS2 running ICS, score higher/better scores for 3D graphics, than the SGS3 does, using either Quadrant, CF Bench, or AnTuTu... surely the SGS3 should have BETTER 3D hardware...?)
I tried v6.1.1 and working so far.

I doubt it is just confined to GMaps as other issues crop up, not just with me, but other guys on this thread and elsewhere. How to reach out: Android = Google = Gmaps. Samsung are in bed with Google. Throw the phone back to Samsung and use the forums, eventually they will roll over and tell Google to stop snoring, get up and do something. Oh I wish.
Hi,
I'm having similar issues but I get the screen locking on both Google Maps and also Sygic Maps.
Anyone else having this issue with more than one GPS SAT NAV software ?

It shouldn't do that. Faulty unit, send it back.
I dont use the Satellite version of Navigation very often, but when you select walking directions it defaults to the satellite map. I was out cycling a couple of weeks ago and selected the walking directions, the satellite map got stuck and glitched exactly as per your description.
The reason your poll is soo heavily weighted as a no is it dosnt mention this issue is specific to using the satellite map.
Just a brief note to say that I too tested an OLDER version, 6.1.1 today, and found that it worked fine on the three journeys I tested it on, with Satellite Imagery turned ON.
So well done to that man - and whilst it still could be a combined Google/Samsung to blame flaw, it does give hope that it is software only issue, that can be fixed with a new version of Google Maps.
As for the point about the poll appearing flawed as it does not specifically state "if Satellite imagery is turned ON", then very good point - my bad!

That is a very good post, and thanks for making the effort. I hope the Mods do not delete it. I'm sure they wont. We all have to make whatever contribution we can to get the product right. In essence, both the SGS3 and SGN have a uniqueness that is not repeated by any other manufacturer yet. I have tried to seek alternatives that satisfy my needs in the way the two Samsung products can potentially do, but there are no realistic options. However, in their current state, I'm keeping my wallet firmly closed until Samsung/Google get it sorted.

GPS lock issue, finally solved !

Hi guys,
Many of us, including me, got a GPS lock problem. We have problem to get GPS lock in a decent time and when it got a lock, sometimes, it will loosed again.
I have read many post regarding this topic, some argue that it was hardware, and some tells, it was software.
Well, in my opinion, both were true, GPS signal in this phone is low or even below average.
But recently, I found the cause. For weak signal, probably, it was hardware, nothing can do with it, but for locking issue, I am pretty sure it was software problem and can be fixed by changing ROM.
I tried a few ROM based on 10B, but none gave a good GPS Lock. Then I tried another ROM based on 10F and 10G, and both were good.
First boot, when ROM just installed, I got GPS Lock around 10mins, but after that, it could lock under a mins, sometime even sec.Booting again, still gets a decent time in GPS Lock.
So I think it was software issue and can solved it by change it to a different ROM. Btw, not every ROM based on 10F or 10G has a good GPS lock.
EDIT : GPS lock is tested without using Internet connection via data mobile or via.
EDIT : PM me if you want to know ROM that have a good lock on GPS, can't write in this post due regulations, sorry.

Sure
Every time:
1) turn on mobile data, wait until it shows your H/4G icon.
2) open gps status and let it to DL A-GPS data.
3) ready, your lock is in 15 seconds max.

Yes, but even it is in a heavy cloud condition or medium rain, locking is still quick.
Just a quick note: GPS lock can be very quick if your compass calibration is right. Just recalibrate your compass.

I think the Compass is the problem with my phone. When I am in MAPS and driving North and stop, the pointer moves east to west. When I start driving again, it'll continue it's course, but occasionally it'll think I'm turning and try to reroute me back on course. I'll try calibrating my compass and test.
Update:
My Compass seems correct, but it's turned backwards in Maps. Maybe there is a problem with Maps detecting the compass settings.
The Tool listed quoted shows North to my left when sitting at my desk. Open up Maps and my heading is pointing to my right (south) when it should be facing my monitors (I'm facing East). So Maps has my compass off my 90 degrees which throws off my Navigation.
It almost seems like it's trying to point in landscape mode, but when I do that, the screen spins and is off again.

This is nonsense. A COLD start on a GPS will take NO LESS than 10 minutes and quite a bit longer if you don't have a clear view to the sky and satellites in view. Period. So if it's "quick", which I presume is nowhere near 10 minutes, it's not a cold start. Therefore it has ephemeris data, which is what the internet connection (A-GPS) provides.
I got GPS to work on my phone by flashing a stock rom, obtaining a solid lock, wiping, and then flashing cm11. Lock held. i remember having to do exactly this for the droid 3 (or maybe it was the bionic) for gps to work. it's a pain, but it worked for me.

Cold or Factory: The receiver is missing, or has inaccurate estimates of, its position, velocity, the time, or the visibility of any of the GPS satellites. As such, the receiver must systematically search for all possible satellites. After acquiring a satellite signal, the receiver can begin to obtain approximate information on all the other satellites, called the almanac. This almanac is transmitted repeatedly over 12.5 minutes. Almanac data can be received from any of the GPS satellites and is considered valid for up to 180 days. Manufacturers typically claim the factory TTFF to be 15 minutes.

So your device has empheris data. Maybe stale. But it's there.
And yes, it uses A-GPS by default. Zero chance it doesn't.
So I just turned on airplane mode, cleared AGPS data and rebooted. Less than 2 1/2 minutes to get a lock indoors. D801.

Have you look at gps.conf file? A-GPS is not enabled yet in that file.
I see you have nexus 7, this device is not A-GPS supported, but it also got a lock even faster than G2, even not in a very clear sky view.
