[Q] GPS problem - Galaxy S II Q&A, Help & Troubleshooting

Hi,
when I try to use some gps navigation app, there are 2 cases:
or it take a lot of time to find gps satellite
or it doesn't find one at all
I found the thread:http://forum.xda-developers.com/galaxy-s2/help/finally-gps-fix-solution-1-5-years-s2-t2272712
but I don't understand what to do
thank you.

What kind of ROM do you have? have you enabled "High accuracy" in the GPS control panel of Android? it will speed-up the fix using A-GPS (it downloads some data from the cellular network to know which satellites listen for).
Try GPS Status from the market and see what's going on

There should be an option saying "use cellular network and WiFi to increase the GPS accuracy".
I'm running Slimsaber 4.4.3, sorry, forgot how does it look like in the stock rom But it should be there nevertheless.

After trying out many different modems, apps and so forth I was finally able to find a solution for me (see post 2): http://forum.xda-developers.com/galaxy-s2/help/gps-galaxy-s2-i9100-cm11-m7-t2808214#post56014923

use a root explorer such as ES-File Explorer and navigate to system/etc/, find gps.conf and open it with a text editor and copy your findings here.

AT&T Samsung Galaxy S II GPS problem (GPS doesn't work)

Hi all!
Please help me to solve the problem with GPS on my SGS2.
It doesn't work at all in any navigation app, though GPS test (app from market) shows, taht the device can see a couple of satelites.
My configuration:
2.3.4 android
Kernel: 2.6.35.7
Build: UnNamed ROM v1.2.0
PS
I live in Russia. Can it be so, that GPS works only in US?

I had the problem as well.
I downloaded GPS Test and started it.
Go into Menu|Settings

My GPS works fine now.
Have you tried an app like this one that is known to have support for Russia?
Thank you all for your support guys.

If it still doesn't help, FasterFix from market should be able to be another way to do your gpsconf settings correctly.

Really great app! Thx!
Easy way to change the gpsconf file!
I was having problems with my GPS as well where it would not lock on no matter how long I waited. I did not have this problem when I first got my phone and I'm not sure when the bug was introduced. None of the software fixes worked for me, including the ones discussed here, and the problem persisted across all ROMS, including stock.
Finally I found someone in a forum that recommended removing the battery while the phone was on. I was hesitant to do this for obvious reasons, but my frusteration drove me to desparation and I tried it. To my surprise the GPS works good as ever and typically locks onto my location in less than 10 seconds. Obviously if you can get the software fix to work for you, this is better, but this was the only thing that worked for me. Hopefully this will help someone else.

What should the agps settings in gps.conf be set to?
I already set ATT=0 and used Faster Fix, but still locking/fixing is very slow, sometimes taking hours.
Could this have anything to do with my location? I am in China now, have unlocked the phone so using on a local carrier. Last time I was in the US (using it with ATT) it worked great.
Solved - SGH-I777 GPS fix
The sirfgps.conf ATT_NETWORK_OPERATOR=0 did nothing for me on my AT&T SGH-I777.
I got that GPS fix app and gps worked but its full of spam adverts that show on your notification bar. They appear with a star infront of the spam advert.
I fixed it the old fashion way. By remembering how I fixed my AT&T Galaxy I gps issue.
in /etc/sirfgps.conf leave att_network_operator=1
change, SSL_ENABLED=1
save and exit
in /etc/gps.conf change the following:
SUPL_HOST=www.spirent-ics.com
SUPL_PORT=7275
save and exit.
now I get 7 second gps lock in Miami Fl.

[Q] How can I test GPS on custom ROM?

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 ?

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.

my S3's GPS not working

hi guys i have been testing my galaxy s3's GPS. i am using osmand app as my GPS app. sadly the app could not find any satellites and pin point my current location. even if i leave my S3's GPS active for a more than 5 minutes it could not get any satellites even if i am standing on a open area.
what should i do? how can i reset my GPS?
thanks in advance
Turn mobile data/wifi on and then try to use GPS. If GPS receiver doesn't have fresh AGPS data, cold start will take from 10 minutes to infinity.

Agree with you. Turn mobile data on. GPS or Glonass receiver use mobile network to fix the signal. When your position is done, you can turn off mobile data.
oh do you really need the mobile data active? was it possible to get your exact location without the use of wifi or mobile data? just your GPS? because osmand can download the maps offline then just use the GPs data to pin point your location. have you guys tried using the osmand app?
thanks
GPS receiver needs to download some (4-5 kilobytes) of data from server. This is called A-GPS, Assisted GPS. Without it, GPS still will lock onto satellites, but it will be 20-30 minutes instead of 2-3 seconds.

U only need data/wifi for first location fix and to dl. extra GPS data.when your location is found,u can turn of data/wifi and never use it again if u got downloaded maps.
Its just to get faster location fix on first GPS fix
I just tested my s3's GPS today in open air and got a lock within two seconds. phone locked 15 satellites. My phone is running completely stock rom and kernel.
So as others suggested, you should turn wifi or mobile data on so that A-GPS could work.
If you are worried about your app downloading more data and cost you money eventually then you may try app named "GPS Test". Its a very simple app and gives you some key info like satellites in view and locked to plus accuracy etc. It doesn't download any maps etc. Once you get locked, you can close the app and open your desired maps app.

hey thanks, because last night i was testing my s3's GPS if i have wifi connection my S3 can fix my current location around 2~3 seconds. i also saw my cousin's s3 and he also gets a fix location within 2~3 seconds. but i am not sure if his mobile data is active. that i would like to ask him again.
hehe thanks guys
Hi there,
I also have an issue with my GPS. Navigation is stuck at Searching for GPS.
Also when I run GPS test, it does not see any Satellites. I have my mobile data and WIFI on, and also tried to update the agps data with fastergps.
I have found different threads suggesting to uninstall maps but that did not help either.
Any ideas? (the issue existed on 4.0.4 stock, and also on latest aokp 4.1.1 build 3)
Thanks.
Also the GPS icon flashes briefly (like twice) and then disappears. Watching the notifications the same thing happens - Searching for GPS- appears briefly and then dissappears.
Is this the normal behaviour?

That usually means the phone has stopped searching for satellites for any reason, these usually are app-related.
Please download GPS TEST from Play store and report if it can find and lock on any satellites. If not or if it keeps loosing the connections, then something is wrong.
Make sure you don't let the screen turn off during the fix since that will disable the GPS.

I have tried GPS Test and it sees 0 satellites. I have also tried a couple of other apps with no success.
Even with GPS test running, display on, I still observe the same flashing of the icon and notification popping up, then disappearing after 2 seconds and reappearing again...
Have same problem. I tried GPS test. It take about 5-10s to lock the GPS. However, it will dropped after sometimes.
If some of you guys are not running stock ROM, then there might be kernel related.
I tried Temasek's newest kernel yesterday on my AOSP MIUI ROM, but couldn’t get a gsp fix.
Went back to siyah kernel and got fix within seconds.
Also try setting your regional pool with fasterfix

Aluminum Case
I thought my GPS was busted as it showed which satelites were available (agps had downloaded) but it woudn't lock.
I then took my aluminum case off the phone and discovered that this was interfering with the GPS lock.
So take your case off before assuming that the GPS is buggered. *sigh*
"My gps wasn't working on my phone. I took it to the Verizon store after I had flashed back to stock, they messed with it for a little while and then ordered me a refurbished one. I received it the next day and when I powered it on guess what the gps didn't work. So I called tech support and to my surprise the person that answered the phone actually knew what she was talking about.
She told me the gps issue is a Samsung issue, (even though is only effects Verizon and sprint phones) they are working on an update to fix it. But in the mean time she told me how to do a work around to get it working. Here is what she had me do."
Go to Settings
Application manager
click all at top
go to Google services framework
clear data
go to settings
Application manager
click all at top
go to maps
clear data
uninstall updates
Go to location services
turn off VZW Location service(leave it off to)
Power cycle phone
update maps from android market
now the gps should be working.

[Q] FM Radio and GPS location problem

hi all.
at first i wanna apologize for my english, i am not native. i am also not good at phones, just normal user.
i bought samsung galaxy s2 i9100 from cellsnmore through ebay. i had to upgrade firmware from gingerbread to 4.1.2, i did it with odin because it could not been done by kies.
what is a problem is that my fm radio cannot find any radio station, headphones are plugged in and normally works with other music apps. after pressing a search station,, it shows that none of stations are available.
another problem is with gps location. i wanted to find my location in accuweather app or navigation and it took so many minutes so i gave up.
please, could anyone respond and advise me how to solve these problems?
any help would be greatly appreciated
thank you guys

Is GPS taking a long time to locate with AccuWeather only or in other apps as well. For example, is it working well in Google Maps?
You could also try to use a GPS Test app (AndroiTS GPS Test Free from Play Store) to check if your phone is "seeing" any satellites or not.

and does anybody know anything how to fix the radio,please?
thank you
How many sattelites are visible as per the GPS test app?
Could you please try the following:
1. In Settings > Location Access, disable and re-enable "Wi-Fi & mobile network location"
And check if GPS works (ideally using the GPS test tools).
2. If the previous solution didn't work, then
In Settings > Location Access, disable "Wi-Fi & mobile network location"
And check if GPS works (ideally using the GPS test tools). (The second problem I had faced with CyanogenMod based custom ROMs in 4.2.2)
Note: The first time you connect to GPS it could take a long time (long as in 20 seconds to a couple of minutes). And if possible, try to test it from a place with clear visibility of the sky (at least the first time).
