Help! GPS has stopped working (t-mobile uk) - Galaxy S II Q&A, Help & Troubleshooting

Hi there - wondering if anyone else has experienced this or can help me. Have seen some similar-ish threads dating back many months but nothing exactly seems to answer this
Until last week, the GPS on my S2 was working fine. Always locked pretty quickly etc.
But for the last week or so, I cannot seem to get a GPS fix AT ALL. I have tried restarting, clearing the aGPS data, etc. etc.
I have installed GPS Status and GPS Aids from the marketplace as recommended in some places. GPS Status shows many satellites being detected in grey, but nothing locks on to them. My phone is not rooted so I have not tried to alter settings etc. as yet, as not really sure this is the problem as I have not changed anything recently. (Could t-mobile have done something on their end that is causing it maybe.. ??)
I am running stock ICS on t-mobile.
Any illumination anyone could offer would be most appreciated!
many thanks

Have you flashed any rom?

Even if it was a carrier update, no need to be a custom rom.
I use GPS-Test to "test" my GPS, can you please install it tell us what is the biggest SNR you get?
I think you will only get a lock if you have at least 3 sats with SNR above 30.

i was using gps status and aid like you did. didnt work till i tried gps test plus.

Many thanks for all the replies
@arc Have not flashed a ROM, just using stock ROM which got upgraded automatically to ICS from gingerbread a few months ago
@zedread Installed GPS Test and tried it briefly just now. Get 7-9 satellites with SNRs of between 20 and 40. All of them stay grey and none of them get used for locking. This is similar to what I have seen in GPS status etc. (i.e. it seems to find satellites but does not proceed to try and lock any of them...all of them always stay grey)
@happily can you advise what it is in GPS Test Plus that helped? Just got the free version at the moment.
Anyone have any more ideas?
Many thanks

Try FasterFix from Google Play Store.....good luck.

[Q] Thunderbolt GPS location incorrect after root

I rooted last night and ever since the HTC clock/weather widget and Google Maps shows my current location to Westland, MI which is definitely incorrect.... I live in Nashville, TN. Any ideas? Thus far I've tried all the basics, restart phone, turn off phone w/ battery pull for 30 seconds, clear data on weather apps in phone, and ofcourse toggle GPS on and off several times. Everytime I turn GPS back on and it "locates" me it gets it wrong. I've tried all of the things suggested for older HTC devices with the same issue with no luck. Any help would be appreciated! Or maybe this is some divine sign that I should move to Westland to see what is in store for me.... Thank you to everyone here for all that you do!

+1 for that app, i had to use it all the time with my HTC Hero. my GPS on my thunderbolt has been good so far, fingers crossed.
still didn't work??? As far as I know I followed what you said exactly... Thank you so much for your help!
Got it fixed. Basically while rooting, i gained root succesfully but I what I believe happened was i flashed the custom firmware twice, instead of flashing the downgraded one first, and then flashing the customized firmware. I realized this because I noticed "S-ON" in the bootloader, so I started from scratch and boom, it was fixed. I noticed the location was off and when I was driving around today it was changing my "location" to random places, and also each "location" change would also change timezones... (went from 11:18AM to 5:18PM actually one time, within 5 miles of the different "locations"). So hopefully no one else had this much difficulty paying attention like I did, but if you did, here's your fix! Now rooted, S-OFF, and all is well here in Nashville. Thanks!
Go predators! I live about 44 miles down the raod east of nashvile, however i cant help u eith your problem

CM7 GPS Issues

Hello again. Recently I created a topic dealing with low call volume in CM7 and fortunately that has been fixed with the help of pcpark(numbers?) and myself. Unfortunately, I cannot for the life of me get the GPS to work. It was working in previous build but the latest July 4th build does not seem to want to lock. I am using the official ED04 modem because of the missed calls issues due to EC09 and I previously used ED01 but without result. Google Maps puts me relatively close to my home address and with Wifi it's pretty much exact but the GPS symbol never stops flashing, indicating that it's still locking. Navigation is completely broken, as it says at the bottom "Searching for GPS" but most of the time it never locks or if I get lucky it will lock for the duration that I'm using it but when I try to open it again, it won't lock. GPS Status displays that my phone's GPS is working correctly but it too has the flashing, not locked icon. Is there anyone who has been having similar issues or does anyone know of a fix? This ROM is so close to perfection and GPS is hardly a huge issue but it irritates me because it worked previously.
Try downloading GPS Aids and GPS Tests to see how many satellites you see and how many you lock on. I couldnt get a lock after 30 seconds on my fascinate ran aids and literally went from seeing 5 to 11 and from locking to 1 to 9 in under two seconds
Holy crap it worked!! Thanks a lot
Np, glad it helped.

I remember reading something about using GPS Status to "wake up" the GPS and I have always used it but I did not know you could reset the GPS. Thanks for the help!

[Q] GPS not fixing position - Morrisoft 0.8

Hi guys,
I've been using Morrisoft ROM since version 0.7 and since then, after some period using the phone the GPS simply stops to fix position and it never comes back, only with fresh install. I've tried with GMaps, it shows huge area of confidence, and with sports tracking apps like MiCoach or Endomondo I've had no success either: it keeps trying to find satellites without success. I've also tried to install the GPS fix provided by Notorious544d for Neutrino, but it didn't work also.
Does anyone have a clue of what's going on?

well,
my friend i have used tens of roms and costum roms, with this phone locking gps is almost impossible.
it's a shame because it is a beautifull phone but i got good gps with old phones like samsung i7500 and htc hd2 i can not understand why this phone has this weakness.
also tried gps fix apk and agps usa fix not results.

Gps Problems

Hi, I bought a Motorola Atrix in Amazon 2 months ago. Since start the Gps din't work at all, 0 in view in apps like "Gps test". I tried almost everything: changing gps.conf, flashing radios, using custom roms like Nottachtrix and CM7, and reverting back to stock via rsd. Btw, a friend of mine who bought the same phone at the same time, had problems with gps in stock rom, but after flashing CM7, it worked just fine.
So, I ask you to help me giving any ideas to fix this.
Maybe this can be useful: The Atrix came with Italian retail rom and N_01.100.00R radio.
Thanks a lot.

If you use an app such as GPS status do you pick up any satellites? It seems to be a common problem to find the satellites but not to be able to get a lock.
Also is you install GPS Status it will allow you to update the agps files.
Did you try gps lock with data access enabled? And as eddhard said do you pick any satellites?
In the gps settings menu turn OFF the options to use mobile networks or wifi. Then use the gps status or gps test app outside in a clear view for a minute or two. If it reports an accuracy distance as 0 or an error there is an issue with your gps that I might have a solution for.
For no reason my gps straight up failed to get a lock. In the test apps, it would see 9-10 satellites with strong signal but never wanted to get a lock. Multiple multiple factory resets, formats, any other variable I tried to change and the issue persisted.
I've attached the file that fixed the issue for me. Extract the libnmea.so and place it in your /system/lib folder after you make a backup of the existing file. Let us know if that helps.

Thanks for your answers, the problem isn't the locking of any of the sats. Test apps show "0 in view" even on outdoors.
I don't have a solution. But I've had a lot of difficulty with GPS on my Atrix as well. I can get a lock usually after a minute or so, but then the GPS would go to sleep. So if I'm moving or logging a route, it'll show me where I started even after several minutes. I flashed radios, updated gps conf, and used GPS Status & Toolbox to get a lock. Still no improvement. It helped me get the initial lock, and didn't resolve the freezing issue. I eventually gave up and bought separate GPS. So I'd be interested to know if you find a way to fix this.
Guys, if you don't see any satellites in GPS Status app, maybe is hardware issue. If you have warranty, use it. If you don't, try to disassemble your phone and look. Maybe just cable is disconnected or has bad contact. Of course be very careful with disassembling or ask someone with experiences. Youtube guide how to change digitizer on Atrix could be useful.
Good luck
I had problems with GPS fix on AT&T atrix 4g with N_01.100.00R europe radio. After flashing 37p at&t radio gps works perfectly, fix is really fast.
Also WiFi signal strength increased.

Same old GPS problems

Hello,
This is nothing new - this device has GPS problems with custom firmwares. However, I wanted to share my experience and thoughts and clarify a thing or two. Tried different ROMs, radios etc. with no success to get stable GPS for daily use with latest ROMs. So I discovered that GPS on older ROMs works differently than on newer ones. For example:
On CM 7.2 - GPS Status&Toolbox gets green even with one sattelite (fix/sat - 1/1) - it can get fix to 10+ sattelites but will never get a lock no matter how much time I'm waiting on it.
On CM 6.1, B 0.8.4, and probably stock - GPS Status&Toolbox firstly discovers sattelites (yellow), it needs at least 4 or more sattelites (yellow) to get a fix. Once it gets a fix (for example 4/4) it changes to green color and gets immediate lock. This is also how it works on my Hero and usually is pretty fast.
So could this be a GPS driver/software problem in the ROM and why can't we get it to work on CM 7.2 the same way it's on 6.1?
I really want to be able to use newer, beautiful custom ROM like HomICS, AOPK, but since there is GPS problems on them I'm stuck on 6.1 or stock.
Cm 7.2 is one of the few roms were GPS actually works properly for me, I've written much about my GPS experiances in quite a few threads and some of my own threads, have a look around, they might be worth a read.

Yes, I did read some threads even yours and tried practically everything mentioned there but without any luck. I've got a few locks with CM 7.2 but it was couple of times when I first flashed it (mobile network was active (3g), however, I dont use it, ever) and the next day it would fix to 10/10 or more but without any lock.
Even today I got practically immediate locks with 6.1. in 10 to 20 seconds. Frustrating that this is not working the same way on 7.2.
How about you, in GPS Status&Toolbox, is your device fixing to satellites one by one (becoming green) without getting a lock? Or it needs couple of yellows before it gets a fix?

I have found that GPS status and toolbox doesn't fully work with the legend, mainly using the clear GPS data and for downloading a-gps data. I used quite a few different apps and basically pulled my hair out through shear frustration till I found something that seamed to actually work.
I use GPS test by Mike Lockwood from the market, this seams to work for clearing GPS data and download a-gps, but generally don't use it as my primary GPS app,I use AndroiTS GPS test free from Alessandro Bonetti also from the market, but for some reason is very hard to search for.
Personalty on my device these apps are the only 2 that give me constantly good results were all the other GPS apps I've tried didn't.

Yes, I did read your thread and tried these apps too. With AndroiTS I was getting elev azim data but no success in getting it to lock.
What about your lock time in daily use, seconds/minutes/ tens of minutes?
I use cm 7.2 (latest nightly) out in the open my lock time can be any where between a few seconds (maybe like 10 seconds) and a few minutes (2-3).

To make things a bit more complicated, after using GPS once, I have to restart the phone. Otherwise, it will not lock again. The first time it will lock in under 1 minute.
On CM 6.1, B 0.8.4, and probably stock - GPS Status&Toolbox firstly discovers sattelites (yellow), it needs at least 4 or more sattelites (yellow) to get a fix. Once it gets a fix (for example 4/4) it changes to green color and gets immediate lock. This is also how it works on my Hero and usually is pretty fast.
