Hello guys.
Just bought SGS2 with 2.3.5 ROM, and GPS was working Excellent(!) (Aroud 15-20m accuracy). And It was moving while I driving a car.
Yesterday flashed into Slim rom, now GPS is working like my old Captivate phone - it is not working Around 1600m accuracy and it is not moving while i drive a car. (The rom is great, except GPS).
I forgot to do screenshot of my previous ROM's modem name. Now I don't know how to fix it I use GPS often.
Tried FasterFix and FasterGps programs, didn't help.
Does modem affect GPS accuracy?
Please help me. Thank you.
Check GPS fix and Faster Fix from market..

Change modem
Change rom

It fixed my GPS accuracy from 1600m to 40m, but navigation is still poor. While I move, profile picture moves first and arrow moves after some time
Didn't try to flash another modem yet.
Try the patch in my sig (make sure you read the first page of the thread before you do; take particular note that you'll need to flash every time you flash a new rom).
Try GPS aids from the market. For me its the best tool to fix GPS problems.

yesterday I installed custom Rom (HyDrOG3N-ICS 02.04 ) on my galaxy S2 and now I am having problem with GPS signals, can anyone confirm if they are able to use gps on this Rom. thanks
Can't confirm GPS works on this rom as I don't use it, but in answer to the question raised in the subject of your post, you can test GPS with GPS Status from market. Shows all kinds of useful details/info (and comes in a 'lite' version w/ads if you're averse to paying for apps )
When I first installed the rom, gps didnt locate me when I used google maps. I just used gps fix from the market and it found me pretty fast.

I have tried GPS Status from market it did not catch any signals. I am a bit confused between, its hardware problem or software
You may test to flash other radio.
It's not HARDWARE considering that it was working on your old rom
moden and gps?
is there any connection between this 2 ?
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.
hello all.......not sure if there is a thread like this already, did a search and didnt see anything on how to get the note gps to lock on better that actually worked for me. since switching to a JB rom my GPS has been horrible. i did an online search and came across an app called FasterFix. i actually used two apps......the GPS Status app and the app called FasterFix. GPS Status worked ok by itself but when i used the FasterFix app with it i get a lock as soon as i open any maps app and its always spot on to my location. this is the best ive ever had my GPS working on any version of android ive had. if your having problems with your GPS give this a try and see if it helps. Worked for me!
FasterFix - https://play.google.com/store/apps/details?id=com.Double.FasterFix&hl=en
GPS Status - https://play.google.com/store/apps/...wsMSwxLDEsImNvbS5lY2xpcHNpbS5ncHNzdGF0dXMyIl0.
Good one!
faster fix changes the ntp server. so only needed when you have flashed.
this next step can be done as often as you like.
GPS status- go into settings-tools-manage a-gps-reset
go into settings-tools-manage a-gps-download
exit program.
turn off gps.
turn on gps.
profit. (you may need to restart phone)
gps test also has the a-gps reset/download feature in it.
Also try some of the gps.conf files floating on here to see if it helps.:silly:
Hi, I'm writing you now because I feel desesparated.
I've searched many forums included this but I can't solve my GPS Signal Issue. My phone won't get any gps signal from Waze, CoPilot, Google Nav... I've tried to fix the GPS with "Faster Fix" (I've chosen the right country) and even "GPS Status" and "GPS Fix" but none of them solved the problem.
I remember the GPS to be working before but it may be related to my rom or modem.
I'm running my Galaxy S2 with the latest NEATROM 4.9 with the Philz Kernel that comes with it. (Gps doesn't work with Neatrom 4.8 as well)
I really need help, I hope its not a hardware problem! Perhaps I have to flash another modem?
Thanks a lot :crying:
I don't think modem and gps are related mate. Try flashing a stock rom first.

Try this thread. But yeah, back to stock to test as Neo said. Correct, modem has nothing to do with GPS beyond the obvious - if you're using A-GPS then having good mobile network connectivity will enable you to get a faster/more accurate fix (particularly in situations where non-assisted GPS won't work well - inner city with lots of tall buildings/poor line of sight to satellites). Changing modems won't help you get a better fix with 'ordinary'/non-network assisted GPS.
Edit - Also, the following has always solved any (minor in my case, I've never had major dramas with GPS) problems I've ever had:
If you don't already have GPS Status, get it from Google Play. Go outside to a place that has good line of sight in all directions. Turn mobile data & GPS on & fire up GPS Status. Go into tools/manage A-GPS state & reset A-GPS XTRA Data. Then go back into the same setting & download new ephemeris data (which is essentially tables of satellite positions/where they'll be & when), then close GPS Status. Turn off mobile data & put the phone into flight mode (leave GPS on), then fire up GPS Status again. Wait for as long as it takes (normally not more than 5 minutes) for it to get a good/accurate fix (down to a few mtrs/with plenty of satellites). This has always enabled me to get accurate/fast fixes for anything up to a couple of weeks until the ephemeris data gets old, in which case you repeat the process as required.

I quite don't understand the steps in the thread you gave me, the explainations aren't clear. I don't even find the gps.conf file in my sd card...
The tip you gave doesn't work as well.
I'm going to opt out for a stock rom, but I remember my gps to be working on a custom rom.
I'll try to reply as fast as I can with the stock rom tested
I don't think I'm going to install a Stock rom, I've tried the GPS with the latest Resurrection Remix rom and it locks a satellite in 5 minutes' time.
So I know that the problem is not hardware related and no need to try a stock rom. The issue is to be found in the way my gps in configurated. It takes too much time to lock my position.
I may go back to Neatrom 4.9 and try to solve the issue from it

Sorry to break it to you mate, but I suggest you try and make sense of it. Because @MistahBungle has just given you very clear and well explained instructions. If you can't understand them, you're not reading enough. :good:

I didn't mean MistahBungle's explainations. I tried what he told me to do but in vain. I meant the instructions in the link he gave me, it's quite complicated... And if you have totally understood them, feel free to explain me
EDIT : I've flashed StaticNav 1.1 and his GPS Exynos file as well, and still the same
SEE POST #4 FOR MY FIX
Got Phone a few days ago and have been trying a few ROMs. Across the board with all ROMs I seem to have GPS issue. I use GPS Status and Toolbox to see when my GPS has found enough satellites to acquire my location...then I can run Google Maps/Navigation.
Is there a fix for this? I'll take any information I can get.
Thanks

Try it.
I wrote permissions to rw-r--r--
Didn't work
Tried dailing *#*#46360000#*#* and then just disable/re-emable background resource control option.
I tried that with reboots between every step?
No luck?. The GPS works just once then not again. On every ROM I've tried.
Edit: flashed MODEM 419D. Will test. 1st test good a couple miles away, but first run always is good after a flash. Will update if this modem fixes problem for good.
Edit ² - FIXED (so I thought) Flashing modem fixed GPS (& BT headset) issue. Multiple Reboots and tests confirmed.
Modem(s) found here: (under developer)

Edit ³ - by 4:30pm GPS stopped working. Re-Flashed modem and still no GPS lock again.
First, Thanks to Faith27, as that was a close solution to my problem. Changing my GPS.conf file was a good solution to my issue. However, GPS locking can be narrowed down to your physical location. My GPS locking is pretty quick now. I changed my GPS.conf file according to THIS article with preconfigured GPS.conf downloadable files and I am finally happy with my Le Max 2 as GPS is a necessity.
Nice, I 'll try on mine. Mine doesn't found any location at all, just maybe the wifi on the streets. But I'm too sad to give up.
