With the results of the vote in the GPS (possible issue) thread running at 30% functionality, left me asking what are the other 70% of us doing wrong?
I thought this would be an opportunity to gather data for analysis. It is not a chat thread or for discussion on causes, or trouble shooting.
Just maybe something well show up, as it appears Asus doesn’t have a clue and keep blaming the case. While the case does seem to be attenuating the signal compared to my Samsung Galaxy S2 it doesn’t explain the hit and miss nature of the TF201. And we all have the same back panel on our TF201’s.
On one occasion with the TF201 sitting on a park bench found 9 Satellites and used 5. (Using GPS version V 6.8.13) Without touching a thing they all disappeared. Then nothing!
The best I can do now is 1 Satellite found.
Test procedure:
Outdoors only in a wide open space.
Use “GPS Test” from The Market.
Update AGPS then turn Wi-Fi off.
If all reports could be posted in the following format.
1. Model:
2. Build:
3. GPS Version:
4. Satellite’s in view:
5. Satellite’s In use:
6. Time to first fix:
7. Has the GPS worked in previous builds of ICS
8. Did GPS work in Honeycomb
9. First 8 digits of serial No
Just maybe a pattern will emerge.
Thanks all.
1. Model: 64Gb Champagne
2. Build: IML74K.TW_epad 9.4.2.11

5. Satellite’s In use:0

Not sure what you're trying to accomplish here.
There isn't a single Transformer Prime on this planet where GPS works great.
So It is what it is: the metal design is beautiful, but it restricts GPS signals. And as there is no real a-GPS for Wifi tablets(as they have no cell-site triangulation possibilities), this becomes a real and unsolvable problem.
And Asus DOES has a clue, according to Asus there is no GPS on the Transformer Prime. The same as there is no GPS on other Wifi tablets like the iPad's. Asus made a big mistake advertising with GPS before release though.
So if you really want to use GPS on the Prime, you're out of luck and should return it. A full refund would be fair if you bought it early.
I've never been able to lock onto more than 3 and then for only a few seconds. That was with HC and now ICS. If I use my Prime for navigation I use my BT GPS receiver and a full mapping capable app which I've already tested and works great. I suggest if anyone bought a TP for navigational purposes return it immediately.
Non-issue (for me at least).

Ohh really.
Please explain TF201 sitting on park bench found 9 satellites, using 5.
Without touching the device all satellites lost and no further seen.
Don't like the odds on those condoms.
The aluminium case explains the poor signal to noise ratios, not the sudden loss of all reception on a stationary device.

The same reason when you are on the edge of losing a FM or AM radio station it can be crystal clear with a inch of movement. Try to navigate turn by turn with the Primes GPS as soon as you start moving signal is too weak to keep it. If your device just dropped all satellites without any movement it's just a glitch and has nothing to do with the overall problem of the Primes GPS.

Because it sees them but fails to hold them when moving because the signal is weak.. Why can't people accept that?

Yes, this has been pointed out about the aluminum back. But as mentioned we all have the same aluminum back then ...
WHY are some Primes always able to see and get a GPS fix.
Why is ASUS even bothering with updating the GPS driver if GPS in not in the spec's?.
WHY has someone not show GPS results with the aluminum back off?
Off topic WIFI why the frack would I want to use G setting to get good WIFI? That's like not using my 5th gear in the car and staying in 4th.
I love the Prime but the aluminum back shield is a frack up period. Stock seems to have dried up around here (impossible to get). I wonder what's up.
My new Prime had never seen 1 single satellite for the 4 days or so I have had it.
Last night, I open Google Maps and click on Resteraunts and simply pick a Pizza Joint nearby. Then I click on NAVIGATE for it to navigate me there (I was just playing around on my couch in my living room, not in my car).
The bottom of Google Maps said "Searching For GPS" and I said "Fudge It" and just laid it on the coffee table. I closed my eyes and about 12 minutes later (I looked at the clock) my tablet says in a woman's voice "Turn Left on Birch Drive!"
I couldn't believe my ears. I quickly opened GPSStatus, GPS FIX, all that. Then I noticed that Google Maps said "Searching for GPS" again. Google Maps needs a lock to navigate you so It actually got a lock for a split second, which was exciting.
However, the other apps were showing 4-5 Satellites, and they have never shown one before. It wouldn't lock, but the fact it was all the sudden showing some satellites was quite exciting since my GPS had appeared to be Dead on Arrival.
So, if you have time and can stop playing with the tablet, set up a route on Google Maps, choose for NAVIGATION, and set it down, maybe by a window, and wait 15 minutes. Maybe you will get a lock.
In my opinion, my GPS works VERY SLOW. It took literally 10 or more minutes to see any satellites, then started loading a few more slowly till I got up to 5. Again,I couldn't get it to lock onto any anymore, but I was in my living room and I have 14 mature trees in my yard (I am talking BIG trees).
Maybe give that a shot and see what happens. Because my tablet had seen NOTHING ever, but I was only trying it for 5 minutes at a time then I would get pissed.

All Primes will see and get GPS fixes NONE of them will keep it awhile moving.
No one wants to destroy a $500 device but if your willing feel free.
G gets better range with Wi-Fi in general and the Prime lacks good range with it's Wi-Fi for the same reason GPS sucks the aluminum sheild if it's not good enough for you return .

Not true!
My Prime must be bad unit because 97 percent of the time it never sees any satellites and it has had actually only had a fix maybe three times out of 100 tries.
I'd be happy to get a fix period each time I tried
Hence my original WHY with the same aluminum back can some Primes get fixes while others don't even now satellites exist in orbit?
My bad unit is going back. I'll wait for the 700 series or a revised TF201 with a new back. Until then My HP Touchpad running ICS will do for now. Yes, no HD video or camera but that's fine.
GPS works on all other sanctioned Android tablets (with market access).

Sorry I forgot to mention asus terrible qc on the primes I'm sure there's plenty where gps is totally borked bottom line is gps will never function as a turn by turn on primes with aluminum backplates. End of story
look at my youtube video... it was honey comb and nearly perfect...
with new updated ics its worthless...
I don't see any satellites and I have never seen any on either of my TFP's. I have owned 2 so far and they both didn't see any satellites period. My GPS light stayed yellow and never went green no matter if I used wifi or not. So why is mine not seeing any Sat's, but you guys complain when you have a weak signal. I am in the process of trying to return mine I bought from BB, but I am waiting my 14 days to see if they will get some in stock. If they do, the customer rep will send one out to me or the store nearest me, and then I would have to send mine off. That's what the customer service rep told me to do. It's not that big of a deal to me, but the unknown serial was, so that's why I got rid of my first one.

What does stationary device, placed on park bench, mean to you?
Not moving...9 satellites, with a fix, then suddenly nothing. No satellites in range. TF201 still sitting on park bench!
As an aside my Wifi is perfect. In fact better signal strength and bandwidth better than both my phones and similar to my laptop.
I don't want turn by turn navigation (have TomTom for that). Just a occasional fix on Google maps. Wifi is generally too inaccurate.
And I do know a little about GPS. RAIM, FDE and Baro aiding help keep me alive in my 9-5 job.
If you are happy with your prime great.
But do check the bottom of the box your Prime came in. The spec still show GPS. Mine is a late model Prime. So regardless of Asus removing it from the web site I feel I am entitled to some form of GPS functionality.
Happy to do that Wifi assisted and it should work in a wide open space. But it doesn't for 70% of owners.
So my question once again why are the other 30% of TF201's offering some sort of GPS functionality?

I also wonder about this. Why waste the time and effort?
Here's how i fixed my GPS problem:
I pulled out my Galaxy SII. Got a fix in 2 seconds.
True Story.
i can get about a 20m accuracy lock while indoors in a matter of seconds, but it never improves in accuracy.
Satellite’s in view: 0-4
Satellite’s In use: 0
Time to first fix: 2minutes
1. Model: 32 Champ
2. Build: IML74k.US_epad-9.4.2.11-20120117
3. GPS Version:V6.1.1.17
4. Satellite’s in view: Fluctuates but up to 11
5. Satellite’s In use:Fluctuates but up to 6
6. Time to first fix:3 mins
7. Has the GPS worked in previous builds of ICS: n/a
8. Did GPS work in Honeycomb:Yes and Much better before
9. First 8 digits of serial #: BCOKAS02
In Honeycomb It was working very well but since the update its way more flaky, as it will go from 9 sats in view and suddenly lose them all.
#### Any one else notice that the GPS Icon Doesn't Blink anymore unless you click the clock menu and then go back####
Yes it locks on instantly and to a lot of satellites, but from there it goes to hell. I just completed my first run using this phone. The route i take is 5.5 miles but the phone said i only did 5.0. The app i use is called MyTracks and it overlays your path with Google maps. Normally with my old phone it lines up nearly perfectly, showing my path as being on the sidewalk. Well with the note it shows my path as running through front yards and houses, which of course i didn't do. All of that cutting through yards and houses is why my path appears to be half a mile less.
Fyi it is a sunny clear sky so no issues that way.
Has anyone else taken their Note running and experienced similar or opposite issues?
Using Navigon on both S2 and Note. Very accurate except my maps a bit old. So it shows to one way street sometimes. The Note lock within 3 seconds. Don't have your issue

I've taken my note in my car, and I can tell you that I've never seen a smartphone's GPS perform as well as the Note does. I get a lock in 5 seconds or less, and I've seen as many as 25 satellite locks, with a position as accurate as 5 feet for a long duration.
Do you keep your Note in your pocket while you're running, or is it exposed/attached to your body somewhere?
MyTracks and Navigon differ in that Navigon locks to streets, eliminating spurious off-path tracks while MyTracks saves every position report if you have it set to do so.
I used to use MyTracks to diagnose GPS issues w/captivate etc.
So far, I haven't seen any of those issues with the GPS in this phone, however, it is always spot on for me. Actually the best GPS i've used in a phone yet.
I am leaning more towards a faulty unit than a design issue..
The note is in my pocket at all times. I did The same with my old phone. The issue could be that, or maybe it just can't track slow speeds very well but it works fine at higher speeds like when driving. I am going to take it in the car later and drive that same path with it exposed and then again with it in my pocket and see what happens.

No problems with GPS at all here. I've had 10+ satellites locked on inside a building with lots of glass. It was able to pinpoint my exact location within the building.

I'm getting absolutely amazing GPS performance here gets a lock almost instantly and is very accurate. Maybe try turning off mobile networks and just using the satellites. I did that and still get a lock just as fast and is far more accurate at least for me.
worked beautifully for me today in the car

Have you changed any settings in mytracks or do you use the defaults? Is your phone in your pocket or out in your hand?
I did turn off wiring before my run, maybe there's a bug when you do that?
Just got mine yesterday. I had a Galaxy Tablet, used it with WAZE for navigation of sorts. The SGT would always show me not on the exit ramp at a particular exit, difference distance was 100 feet.
The Note shows me on the exit ramp every time, it is much better GPS
So driving down the road with the Note in my vent-attached phone holder, the GPS works flawlessly. When I put it in my pocket, it started getting inaccurate again. I'm not sure why this is the case since my old phone worked in my pocket just fine. I am hesitant to carry the phone in my hands for the 5-6 miles I run, in fear of dropping it. If others report that MyTracks works flawlessly with the Note in their pocket, I may return mine and try another.
18 sat LOCKS indoors. 3m accuracy instantly.
Best GPS performance out of any phone.
I think it's just your app.

I have Runkeeper Pro and Edmondo so I'm going to try one of those next time. I don't like those apps as much because they don't let me see a granular breakdown of my speed throughout the run. Meaning, I can see a chart of exactly how fast I was running all throughout my run. With these other 2 apps it just shows you a total speed at the end of the run, Maybe I can find another app that does what I want.
I use my GPS quite often and I will say there is absolutely NOTHING wrong with this GPS. Best phone GPS I have ever had.

I've narrowed down the issue to it only occurring while in my pocket. I am going to try some other apps or buy an armholder.

er....Never mind
So is this a problem with the Rezound, or the program? I went for a short 20 mile ride today, and Map My Ride showed it to be 28 miles. It's a 20 mile loop by my cycling computer and by google maps, and this is hardly a small margin of error. I've generally had good luck with the GPS but this is a little extreme.
well, one time just using the standard gps, i punched in an address & it showed it to be in the middle of a lake on the screen... õ_Ô
Solar flares interfering maybe. No, seriously they're high at the moment.
Rezound GPS is not very good with any of the sports tracking apps. Someone posted a thread where clearing agps cache helped but it didn't work for me. I still use my incredible for logging my runs. I haven't tried any of the ics roms but I'm hoping they address the problem.

The GPS on the Rezound sucks! I came from the Samsung Galaxy S and it had its GPS problems as well but it got better and better as time went along. Hopefully this will happen again. But I can be in my back yard and when I start Maps it locks right away and says 5meter accuracy, yet it shows me 100-150 feet away from where I really am. So its basically worthless. While driving it shows me driving through buildings and people's yards all the while saying its got a 5 meter accuracy lock.
Part of the problem may actually be solar flairs, but it does seem to be a larger issue of the Rezound doing fine-grained tracking. Here's my supposed ride yesterday--I was riding like a drunk sailor, apparently!
This problem has definitely been happening since before the current solar activity

Hmm. That's odd, GPS on my stock Rezound locks on quickly and is rock solid. I use Google Nav all the time and it works like a charm.

I will have to try this.. I've never had a gps problem on HTC phones. On my Samsung charge.. if the wind was blowing you couodnt get a lock.. my buddies Samsung captivate can't get a lock unless he's holding still in clear view of the sky. If he's driving.. it won't lock at all.
Every HTC phone I have used locks in seconds.. every time, all the time and always accurate.
And you guys realize that if for whatever reason the GPS connot find.you, its going to triangulate off ccell towers, which is never accurate.

For clarification, this is the solar activity being referred too - http://news.blogs.cnn.com/2012/03/08/solar-storms-causing-few-problems-on-earth/
I just noticed that in GB and ICS, it seems to be having the problems start up around the same time (a little more than a minute after the screen goes off, it always seems to start out right though). I'm wondering if it has to do with the phone going to sleep or the apps not being able to prevent the phone from sleeping. I'm going to see if the problem happens if I set the phone to never sleep.

The phone was in airplane mode because there's no signal out where I was riding. Wasn't triangulating.
I think it's probably the uptick of solar flares, or there's a problem with how the Rezound tracks w/GPS. Or both.

Note that aGPS (the a is the assist part) uses the network to provide the assist to the GPS to get a lock. If you turn Airplane mode on, you are turning off part of the ability of the Assist in getting the lock faster. So you can be making the use of the GPS much less accurate as it takes longer for the GPS to get a lock.
Once the GPS gets the lock, it doesn't need the assist again, but some apps don't keep using the GPS steadily, and need to reacquire the lock over and over.
Example, if you are using Gmaps, you will notice that the GPS satellite image will show in the top of the notification area while you are using the app. But when you move away from Gmaps, the symbol disappears. That is because it stopped accessing the GPS.
If you don't see the GPS satellite in the notification area, the GPS chip is not currently being accessed and it is is using next to no power during that time.
Not being familiar with the app mentioned in the OP, you would need to check that the GPS is being used continually.
It is not unusual for stand alone GPS trackers (non-phone types) to have glitches in their tracking as you travel, depending on the speed and access to the sky for the GPS signals. Devices like Garmin compensate for that by keeping you on the road, even if the temp position places you a distance from the road so you don't notice it much there. But if you are just tracking position (no locking to a road), you will end up with jutting points that can be a distance from where you were at the time.
A nice thought, but all these app should be pulling accurate gps even if the app doesn't have the foreground and they should prevent the phone from sleeping.

So I tested the app, 'Myrun' And I found your problem. when the app is in the background, it does not update at the same rate as it does when it is in the foreground.
On my attachment, the green dot is where I started, I went out, up the road, and turned around. The screen was on this entire time, notice how accurate it tracked me. It even has me on the correct sides of the road..
at the Yellow dot, I turned the screen off, notice how it jumps from point to point , making it very inaccurate. If I had to guess, I would assume that the app either A, does not utilize the GPS radio while the phone is 'off', or, it polls it less frequently. Either way, this is not a fault of the phone, as you can navigate with the screen off accurately with google nav/maps. So the phone is capable of allowing apps to use GPS data even in an 'off' state.
I would contact the App developer and see if they can fix it. In the mean time, make sure your phone is charged 100% and set the screen to never time out, and turn the brightness all the way down and you'll get accurate tracking with those apps.
Personally, my phone is set to never turn off, and my bike has a phone mount with a charger that gets power off my front wheel hub.
So all the tracking apps have the same problem and only with the rezound but it's not the rezound?

I can test it on my DINC of you want, I have it laying around here somewhere.. give me a bit and ill run the same route using it instead

I know for a fact the incredible doesn't have a problem, because that's how I've been tracking my runs.
You should still test it though.
I wish it wasn't a problem, I love everything about this phone except for the fact that I can't use it for my running program.

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?
Thanks.

same experience here,running stock
No, not stock. I'm highly modified. I installed a screen protector that I suspect is giving me increased GPS/glonass capabilities.

Hmmm... maybe it's *my* screen protector that is killing the GPS...
A follow up to those who responded:
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.
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.

Hi guys,
I was using the Pace in a running track and it was perfect. Now I started using the Pace to run around a square (which has a square shape), but it is not accurate at the corners. Due to that, I am getting speeds like 18 km/h and I ain't capable of that, for sure. Is there any fix?
Thanks in advance
GPS is measured every few seconds, so if the first one is before the corner and the second one after, there is nothing you can do.
Runkeeper has a function to edit the track and follow the road, that might help ( fitnessyncer can transfer from strava )
NoThanks for the reply.
It makes sense but it is frustrating to see that much error in a single run.
I was thinking if using a gpx file of the course would help to force it to stay on the track. Have anyone done that? Also, it is a circuit, so I am not sure how to make a gpx file for that.
Find attached some photos to see how bad it gets.
1. Make sure you sync watch to Amazfit app often in order to have A-GPS data always up-to-date;
2. Wait a few se seconds before you hit GO to start recording the active in order to get a better GPS fix (more satellites);
3. Tress and buildings can block/reflect GPS signal, adding noise so you won't get a good signal.

- I updated the A-GPS a couple of days ago. I am a little afraid it has something to do with it. Is there any way to force another A-GPS update?
- I always wait for a GPS lockdown. Generally, I hit the run option almost 200 m before starting to run and wait for the green signal.
- I will try to run in an open space just to double check. Maybe the trees are indeed what is making this much noise in the signal.

If you sync daily, probably it is fine. I am almost sure that A-GPS is synced only once a day. You can always force a sync by pulling down from the top on main Amazfit page, but if A-GPS data is up-to-date it won't show anything related to GPS, only sports/health data sync.
Not sure what you are expecting.
1) GPS is creating a trackpoint during running aproximately every 2s. Between 2 points set a diagonal is artificially created!
2) A very good gps reception has an accuracy of +-3m (I think +-10m is more realistic), you will not get it more accurate with recent GPS technology!
3) There are allways signal reflections etc from trees and buildings which are falsifiing the result.
3) You didn't specify the distance one circle represents, but from the building I guess you got quite reliable results.
4) If you know the distance of one circuit you could use the more reliably time measurement to correct the results.
5) A-GPS data helps to get a quicker satfix but is not generally improving the reception of the GPS signal.

Can you try it in Trail Run activity mode and see if that makes a difference? Another poster claimed the trail run activity gives more accurate GPS readings, but I am not aware it has been proven yet.

1. Ok, but I am not making that corner in less than 2 seconds. It should get an accurate read once in a while.
2. I see, but I believe it was not supposed to be all zigzagging like it is actually doing.
3. I agree that it is the most reasonable explanation for the inaccurate readings. It is not only the corners, but the entire track also gets faulty readings.
4. Yeah, but if I were to calculate the stats by myself I would not have bought a smartwatch. By the way, the square has a perimeter of 720 m, being one side 250 m and the other 110 m.
Anyway, thanks for all the suggestions

I will try that! Since the square has some trees maybe the trail mode would simulate/expect the same environment. Thank you!
