I am currently in Hong Kong, using Google Maps on my phone. On my old Blackberries, the GPS is accurate, the arrow sits right on the building I live in.
However, with the S2, it is either off by an entire block, or takes 2-3 tries, and finally narrows it down to within 200 feet of me. I am sitting right next to the window with GPS turned on, and the arrow is sitting on a building across the street from me.
Anyone else have this problem? Is there a fix? Maps is sort of useless to me when I need it the most.
Thanks!
Always been accurate for me outdoors of course less reliable indoors as it cannot see the sky .
Possibly try the latest KG6 modem .
Faster fix from the market and GPS Status may help .

Thank you for the input!
I tried faster fix, the arrow finally landed right on my building, but a couple seconds later, it jumped to a located two blocks away. The other times, the arrow was at least 200+ feet away. I will flash 2.3.4 sometime soon, even though I've rooted my phone, flash custom kernel and all, I am still waiting for that update firmware to 2.3.4 to show up in Kies...
From my remote village, the Google Latitude location is never accurate. It jumps around as you described (I'm still using 2.33 firmware).
However, if I turn on WIFI (even though there's no wifi around...or home wifi is turned off), it becomes more accurate and less jumpy.
When I'm riding around my tuktuk, Latitude is very accurate (not jumpy) if I turn on both WIFI and GPS.

I ask because with my iphone 3g It was pretty much spot on all the time. My atrix on the other hand is about 4-5 blocks(WTF) off. This is only my second smart phone but this seemed really odd to me.
Anyone else with inaccurate gps with out wifi on?
Mine is usually accurate to within a few meters, but I don't let it use wireless networks for it basically ever
I played with this a bit more and for what its worth it turns out that if the gps cannot get a satellite connection it does not warn you. For me it was just defaulting to the center of the very small town that I live in. Which is pretty much within 4 block range no matter where I go. The 'Navigation' app does warn you if it cannot get a connection.
So yeah, the gps is good, when it connects
GPS is usually within 20' for me. Wifi is useless w/o a wifi source to connect to. No wifi when I'm out running on trails. And if I'm at home, don't really need the gps.
My GPS is dead on all the time. Only takes 3-5 seconds to get a lock at about 3m and that's indoors. Only time I've ever had a problem with it was while using shopkick in a deadzone inside Wal-mart.
Hi Guys,
I'm making an article about SGS II and I've found out, that there is again issue with the accuracy of GPS position (like Galaxy S had).
First clue was the article on GSM arena:
The LG Optimus 2X got hold of between 7 and 9 satellites and used 7 of them most of the time. The reported accuracy settled at 5m and mostly stayed there with the occasional jump to 10m.
The HTC Sensation spotted 9 satellites and used them all (more satellites potentially lead to a better lock). Accuracy started at around 8m but quickly reached 3-4m and held steady. Note that this is reported accuracy, but actual accuracy should be proportional to these readings.
The Samsung Galaxy S II performed worst in this test, using all of the 6 satellites that it managed to detect. Reported accuracy went between 18m and 20m but varied quite a bit during the test (even though the phone was completely stationary).
I've used the same application and compare it with Xperia Arc. We were standing outside on one place. Finally I got about 30-40 feet on Galaxy SII (still changing). Xperia Arc started at 10 feet and quickly settled down to stable 3-4.
Does anyone has SGS II and some other Android phone to compare it? I'm curious, if this is problem in general or just few bad pieces on market.
Thanks for help...
I tried GPS + Wireless Netwok assist, GPS test says 10 sats in view my location is not even accurate to 1Km
My GPS is great, never had an issue with accuracy. although I had to find out that my gps.conf says "north-america" as the default nntp pool instead of "europe" on a german (DBT) SGS2 is really strange, still my phone get's a cold lock with 10-20 seconds (10s standing still, 20s while driving).
Mine is very fast and precise - I would say its 1 minute to locate me when im outside with wifi switched on.
Original firmware GPS test was May 2011 .
Lock cold boot never used GPS before
no Wifi No network no AGPS .
GPS only
4 min 8 sats locked on . Accuracy 13 metres ..
Subsequent lock on faster as expected and 5/10 m accuracy .
No further tests as it just works .

I use Navigon three times a week and i never got problems with my sgs2. The gps signal is like my iphone 4, i only navigate with the voice!
Real world driving accuracy : 20-30 meters (can go down to 5-10m, but only in truly wide, open areas)
Lock Speed : few minutes
Barely usable as a navigator, at least in urban areas. The above are under KE7 and KF3. Really disappointed by the GPS performance on mine.
my gps works fine often i use wifi
Changed my NTP server to asia, I can now even get a lock inside the house, sweet!
Guys, thanks for replies.
Anyway I think this issue won't appear that much on driving navigation, as this software "sticks" to the nearest road and use the speed to make the position as accurate as possible.
Bigger problem I see in terrain while searching for way home, or while playing with Geocaching.
Only positive thing is that from digging in ground at area 20-40 feet wide you will surely obtain big muscles
did you guys already look thru this thread? all the good info is in there too.

Hey guys. Coming from 3 HTC Android phones, I never had any problems regarding fast locking and accuracy on my GPS, may it be indoors or outdoors.
With my SGS2, I wasn't really happy with its GPS performance.
Aside from very slow GPS fixing / locking in satellites outdoors (tested with GPS Status app), I get a very jumpy GPS location indoors. Even with downloaded AGPS prior to that.
I created a screen cast of my Google Maps app below for reference. The star on the map is my actual location. Notice how my location jumps from one place to another every few seconds.
Even turning on the sensor aiding made no difference.

I know some of you might say that of course checking it indoors and relying on wifi alone will make it inaccurate. But even my iPod Touch which doesn't even have a GPS chip have no issues locating me.
I'm running Cognition 1.15 and flashing a stock ROM and kernel also made no difference.
Can you guys test yours with my setup: Only Wifi indoors and do not get gps lock outdoors.
I will do further testing.
Welcome to the club m8. http://forum.xda-developers.com/showthread.php?t=1173683
I think it's jumpy because it's not using gps, but fixating you postilion from you network and wifi. That's why it jumps.
Does your gps show lock at the top icons bar? Or does it just keeps flashing?
Mines going back for sensation or lg.
Hi. My GPS icon is flashing. Yep, I'm aware that it is till looking for a satellite to lock in. Which is a problem in itself by the way ^_^
My point here is that I've done this similarly on my previous phones and with my iPod Touch, same setup. But they didn't produce this problem.
UPDATE: Tested out the GPS outside. It won't lock to any satellite (after like 10mins) unless I turned on WiFi. GPS should work independently, right?
Once I had it locked to 6 satellites at max, I went indoors and same thing happened to the screnario on the video, my location jumps from one place to another. Shouldn't it take the previously GPS locked satellite as reference?

It is using the satellite position from last lock to help getting a new lock, but it still needs to have stable reception from 3 satellites in different parts of the sky for a certain time in order to lock, it probably doesn't get this indoors.
But you seem to have some problem getting a lock with your GPS, some people are helped by doing a factory restore when they're having such issues. (beware, wipes your data!!!)
What do you mean by turning on Wifi by the way? Do you mean turning on "Use wireless networks" in Location and security menu? This is not something wifi specific, in fact since you're outdoors it normally uses your 3g connection to get approximate satellite positions and your approximate position from network operator. So please doesn't call this turning on "Wifi", because that means turning on/off you wifi receiver, that is another setting
EDIT: added "in different parts of the sky" above, 3 satellites close to each other is usually not enough for a GPS lock.

I totally understand that. I referred to Wifi because it's the only connection I was connected to in asstistance to my GPS. My mobile data is turned off. But I did test it by isolating only mobile data on to check if AGPS by 3g will get me faster lock on it -- No difference.
I have also flashed a stock ROM and Kernel and fully wiped my phone data but it is just producing the same problem.
To be honest m8 this phone is good on the spec, and looks good too. But poor internal hardware lets it down. I went down to my local shop to see if it was me or something and asked for a demo test for phone they had and they also couldn't get it to lock the gps on it's own.
I feel for andriod, it can give it a bad name. But it's not androids fault it's Samsung, if your phone is new replace it with sensation or lg 3d.
I've even had the opportunity, to try it with CM7 now, so it seems it hardware afterall.
Guys chill down ur balls, gps readings r very subjective and u cant judge on them

Still really disappointed that my iPod touch can get a very accurate gps fix in less than five seconds considering it has no GPS chip and only using wifi. This has aGPS and sensor aiding and yet it's not very accurate and is jumpy still.
Hello everybody, I am new to this forum but I would like to share my experiences regarding the Transformer Prime
.
I bought my Prime in January in the Netherlands. Out of the box it worked with no problems what so ever. After reading other users remarks about the GPS, I downloaded the GPS test and ran the app in the living room of my apartment in Amsterdam ( this was after the first update) within a minuet I had 7/8 sats in use and my location was as good as pin pointed.
I work off-shore in the North sea, and I went outside with the prime to see if I had and signal ( thinking that the steel structure would interfere ) to my surprise, within seconds I had 8 sats in use and my location pin pointed.
Two weeks later and after update number 15, I was in rural France and I took my prime out to the garden thinking that I would have 10 sats within seconds, but to my amazement I only had a glimpse of 2 sats during 15 minuets. During those 15 minuets my TomTom was finding the sats without any problems.
Back in Amsterdam and again off-shore the Prime had no problem finding sats. So what can I conclude from this. The GPS seems to be working OK, and that as far as I can see there has been no performance gain or loss after the updates. I know it possible to have GPS dead-spots ( buildings, pylons etc ) or Is the problem weather related?
With regard to other users remarks about the wifi performance, I agree that signal “fall-off” is a problem. Next to my modem I have 72mps, but 6 meters away in my bedroom I only have 5mps. The wifi performance has also not improved after the updates.
The only annoying problem I have with the prime is after update number 14, when the stock browser would sometimes give me a blank screen. But I discovered that if I swiped the screen up and down a couple of times the browser came back. Since update 15 that has not improved, and most sessions with the browser I end up swiping a blank screen once or twice to get the web page back.
I have not had any problems with re-boots, flickering screens or hanging. PS my prime is still stock.
The GPS in the Prime is flakey. The best test you can give it is to take it for a drive in a car and see if it maintains a lock on 4+ sats while moving.

I get the same thing with the blank screen and also the wait/close message. It is very annoying...........
I wish my luck was so good.
My GPS doesn't work, and I am one of those who doesn't care about it.
What I do care about is that my Prime has decided to no longer play nice with wifi and BT.
I try to stream my Google Music and listen to it from the BT headset... mostly it doesn't work, the wifi dies, the music stops and I get nada.
I didn't mind about the gps, and the light bleed on the edges was only annoying when using the bookreader in night mode if I had the lights off so the wife could sleep..
So, my Prime is headed back to Gamestop and they have no more in stock online, or at the only store in my area to carry them.
Refund time, and maybe by the time they get them back the issues will be resolved, or I'll own something else and not care.
none of the above
I don't know about other units, but my prime is working perfectly.
Just ran GPS test inside my house and within 20 seconds I had lock on 14 satellites.
Wifi works perfectly in all over my house and also outside in the yard.
Bluetooth streaming on Google music, no issues whatsoever.
No issues with the browser.
It's been the perfect device so far.
It seems to vary from unit to unit. A friend of mine has one, no issues, mine, meh....
I'm sitting on the patio, Southside of the building, full view of the sky, and here's my GPS.
The one on my phone is fine, seeing 11 birds. I don't plan to use my tablet to drive, so it's not really affecting me... The bt/wifi on the other hand is a deal breaker.

I've had good luck with my wi-fi on all but one router (had to get pretty close to it). Even got about 10 meters from my mini travel router and maxed out the download speed. Something you might want to try when you have time is to experiment with changing your router's channel at home. Even the orginal Transformer had issues with some channels.
I have an P760 with unmodified stock rom, 20b is the latest I can get here in Slovakia.
It takes really long for the GPS to catch some satellites, with clear view of sky, AGPS and data enabled, I usually get a fix in 90-100 seconds, which seems like really alot to me. Also, after I get the signal, it drops really easily. I was using 'My Tracks' from google to track my movement in the nature, on foot and on bike. The thing is, GPS has lost satellites for around 2 times in 30 minutes, so I have very incomplete and inconsistent results.
I've tried playing with the secret menu and GPS Status app, with no luck.
Is there any software, or even hardware way to increase the performance of GPS? I think there may be some problem with antennas.
Thank you.
