In summary (due to limited/slow internet access via wifi)
* Phone is a stock Samsung Galaxy S2 - v4.1.2 (UK Three network stock ROM)
* I'm from the UK and GPS works fine over there.
* I'm in Europe for holiday and GPS does not work at all.
Changes so far:
- Changed SIM card
- Added new APN, which includes this line for APN Type, which is default,supl,mms,agps and while Roaming Data works fine, GPS is not connecting at all (e.g. Google Maps, Co-Pilot, etc).
Using an app called GPS Test - it CAN find sats (up to 5 or 6 different sats) but NEVER get a fix at all.
Used an app called Fasterfix and set the server to Europe (I have root) - still no luck.
It CAN find a fix (well sort of, location is incorrect but is close by) if I enabled WiFi from our hotel. But useless when I'm out and about.
What else can I try to resolve this as I will need to use GPS in the next few days time (driving using satnav on my phone)
I have tried to do a search here but the hotel's wifi is pretty crappy/slow. :/
I'd be grateful if anyone could help me to resolve this.
Many thanks!

Flash a new rom!
-Root the phone via CF-Root or the App "Framaroot" from XDA , then install CWM through ROM Manager.
-Then download the ROM.zip you want and install it in CWM.

Thanks for the reply, but in case you've missed it, I am in Europe... I cannot risk doing it in case I brick my ONLY phone that I will need for the rest of my holiday. And I got sucky wifi access to download anything anyway.
BTW, seems overkill to do this... does it REALLY work? If so, why does it work when my stock ROM does not work? I'm just curious...

Oh , sorry.
Try to make a backup via GO Backup (best backup without root acess).
Then make a factory reset and restore the backup.
me too past two day.
I tried many rom: CM 10.1, 10.2, stock 4.1.2...but get same problem.
OK. Here's what's always worked for me so far as GPS is concerned, obviously YMMV & there's no flashing/risk of bricking your phone involved.
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).
Once I do this, it's 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. Obviously if you have network connectivity this will help getting a fix, particularly in 'crowded' urban areas (cities/lots of buildings/poor LOS).
Edit - Also, if the above doesn't work, try this. I understand your reluctance so far as flashing anything goes, but you either want your GPS to work or you don't. Yes, it should 'just work', but there's lots of things in the world that should 'just happen' & they don't for whatever reason. This is how it goes with smartphones. The GPS on the SGS2 is particularly notorious for issues that simply can't be resolved easily for some people.
Flashing another rom or kernel may/may not work, if the GPS drivers are messed up, doing so will give you fresh drivers & may fix the problem if that's what's causing it.

Hi Friends,
Few days a go as I was watching youtube videos for around 45 minutes continuously through the youtube app. The streaming suddenly paused and never continued from that point. I tried other videos but it kept on buffering (the circle kept on spining and nothing happened, as noticed on the leds of wifi router it seemed youtube app is not using the net but when i search for more videos the thumbnail do showup normally).
To over come this issue i tried reflashing. This happened when i was on the new HyperDroid_v4.0 with Pongster's MattedBlack v4.0 Surgeons which is amazing for battery saving.
I then tried reflashing HyperDroid_v4.0 again after formatting /cache /system /data /sdcard /emmc which wiped everything, but still no avail.
Then i again tried reflashing DarkyROM2 XXKH3 BASE (2.3.4) formatting everything but still no luck at all.
I even tried these flashing after Factory data reset selecting Format USB storage as well .
When i do the flashing everything else seems to be working fine as usual except the youtube playback and android market doesn't download, like i said for the youtube app, everything like searching the apps, browsing through apps details works fine except it doesn't download at all. It shows as if it's downloading but it stays as is forever.
Very sorry if same question was posted before this as i couldn't find like it.
I have been trying to fix this for 2 days in a row but still no luck.
Has anyone come across this same issue.
Please help.
Thank you very much in advance..
Update:The problem was finally solved after again formatting /cache /system /data /sdcard /emmc and flashed stock ROM though Odin and then I installed DarkyROM tool and then flashed DarkyROM2_KI3_Base ROM.
I will soon jump to HyperDroid_v4.0 with Pongster's MattedBlack v4.0 Surgeons again as it has superb battery life.
I will be updating you guys if the same problem persist.
Thank you all
Hello everyone!
Although I am not using GS2 (I have a Galaxy Note), I chose to post here because I didn't want to create a new post and I believe this is not a device-specific issue (see below for why).
I have the exact same problem as OP (as far as I can see). When I got my note less than a week ago, everything was working great. Then, last Friday I noticed that I cannot download anything from the market. After choosing to download something (both paid or free), after clicking "accept & download" at the permission screen, the screen goes back to app screen and market shows the app as "downloading..." with working, yet empty, progress bar. Everything else using the internet works fine - browsing from different browsers, notifications, email etc. I even tried installing an alternative market app, and it would download/install apps no problem. Also, downloading straight .apk files works as well. Later that evening I also noticed youtube app doesn't work - just the "loading" circle keeps running, until it times out. Browsing/searching market/youtube works without a problem. I am using the stock ROM and it isn't even rooted. Later, following some suggestions from google searches on the problem, it turns out that downloads work when I disable network and let it use mobile internet. I also later found out that it works on other wifi networks, just not my home wifi (which used to work perfectly, with no configuration changes to the router).
Next day I also found out that my girlfriend's android (LG Optimus Me P350) has the same exact problem, therefor it is not a phone model specific problem.
Here is what I tried so far:
Factory reset - left me with no apps and no way to re-download them. The market download did work ONCE after the reset, but that was to download the update to the market itself, nothing else;
Clearing Download Manager data - worked for ONE download. At first it worked for one download every time, meaning, after clearing download manager data, I was able to download one app, after that it would go back to the problem. I could then clear data again, and it would again download one app. After about 5 apps downloaded this way, this solution won't work at all anymore;
Force closing/clearing data of market, gmail, talk (in combination with above step) - didn't work;
Signing out/in to gmail and/or talk - didn't work;
Changing google account in market - didn't work;
Stopping/starting download countless times - didn't work;
Switching wifi on/off - only starts downloading briefly when phone switches to 3G while wifi is off. As soon as it gets wifi connection back, the download stalls at the position it was until I switch wifi off again (so it can continue to use 3G);
Switching phone to airplane mode, off/on, then disabling airplane mode - didn't work;
Changing phone's DNS records with an app to OpenDNS - didn't work;
Updating router firmware - didn't work;
Resetting router firmware - didn't work;
Setting port triggering on router for port 5228 - didn't work;
Port forwarding to Note IP for same port - didn't work;
Disabling router firewall - didn't work;
My router is Linksys E1000.
I think that is all I tried. I have been trying to find a solution for the whole weekend, and nothing as far. Searching google makes me believe that many people have had the same problem. I have found many solutions, which don't work, or only work once. This problem is really, really irritating. Also, I have found out that for many people the problem seems to randomly disappear without doing anything after some time (days to months), sometimes coming back and sometimes not. I experienced this myself when after going to sleep, I was able to download one app in the morning with no tried "fixes" at that time. This also makes me believe that there are many "fake" solutions, which did work for some people, but not for others - quite possibly, while these people were "solving" the problem, it actually solved itself, yet because the person did something, he/she believes that was the solution. A notable example of this could be "google account 24-hour reset" where users experiencing the problem are suggested to log out of their google accounts everywhere and not use the account for anything for 24 hours. Seeing as this is possibly a problem somehow connected to another device, not just the phone itself, I did consider flashing DD-WRT on my router, but I wouldn't really want do do that since my router is not that powerful and with all the DD-WRT features my broadband speed gets capped at about 65Mbit/s. Still a lot, but I have a great internet connection and am able to get real speeds of about 90Mbit/s with stock router firmware.
If anyone has any ideas, please share Thank you in advance!
Just a quick reply - I contacted my apartment building network tech, and he said that they didn't do anything regarding the internet that day, but they did however do something to offer TV service to residents (edit: The TV network shares the same hardware as internet's). He said that it shouldn't have changed anything regarding internet, but he would look into it. A few hours later everything is working.
Of course, it could be one of those cases where the problem disappears with no apparent reason, but I guess they did something to fix it. So, if you are experiencing the same problem (market downloads not working and youtube app not playing videos), and you have tried everything else (preferably confirmed the problem persists on someone elses phone), I would suggest you start going up the chain to whoever is managing your network (after yourself). If at all possible, try getting wifi access through someone else who is using the same ISP/network - if the problem persists even when connected to another AP/Router, it's pretty sure the ISP or network is to blame.
Hope this helps someone, since I wasted a few days on this
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.
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.
Hello,
I am using SGH-i777 outside USA (in Kosovo). I purchased it unlocked so everything works as expected, except GPS. The phone came with Gingerbread (not rooted). I tried GPS through google maps but i was getting "You location is temporarily unavaliable" and the scan was taking ~10 minutes without any results. Applications such as AccuWeather were also not able to find my location.
After this dissapointment, i decided to root the phone and install a custom ROM. I followed the guide posted at this link and followed the steps there 100% without making any changes/mistakes. I installed the Siyah 2.6 Kernel and the ROM that i choose to install was Aberration. I also followed the guides for this and did everything as advised. I turned the phone on but the GPS was still behaving the same. After this, i purchased GPS Doctor and clicked "Quick Fix". After this i downloaded GPS Test to see if the signal was alive, and after ~2 minutes of scanning, GPS Test found around 7 satellites and the signal appeared green within this app. I followed this by opening Google Maps and i got the correct location after ~2 minutes scan. This made me happy and i believed the GPS issue got fixed. But after trying after few hours, i saw that maps was again facing the same issues and apps that require location access were not being able to do so.
And the last step that i did was install a gps fix as posted on this thread. I know this thread states that they do not officially support sgh-i777, but i was out of options so i had to try something else. I followed all the instructions and downloaded and installed the Google Specific v 1.3 from that website. But this did not fix the problem either.
To conclude; the GPS is simply not working as expected. Finding the location takes to long and i was able to get the location in Google Maps only 10% of the time (my old iPhone 3gs finds the location in 3seconds!). I have tried this indoors and outdoors but the problem remains the same. During all the times, Wi-Fi, GPS and Data were turned on
Currently i have un-rooted the phone (followed the guides here) and am currently running the official ICS which i installed through Odin. Tried GPS again and it still does not work.
Sorry for the long thread but i wanted to explain all the details.
Hope someone can help me.
Looks to me like one of 2 problems:
1) You're not getting a good time from NTP server, try downloading FasterFix and selecting your area (need root). Not very likely, since with good GPS you'll still have a fix within 1-2 min.
2) HW problem, possibly antenna contacts.
So any go around for hardware problem?
Sent from my SGH-I777 using Tapatalk 2
HW problems are solved in HW. You can't "go around" and make the bulbs light in your house when the power has been cut off, can you? So how exactly can you "go around" a bad contact with antenna, that practically equals a missing antenna?
Just fix it.
In settings under location services did you check "use internal GPS" ?
Not even sure if aberration has that option. Jelly Bean ROMs do.
Sent from my SGH-I777 using xda premium
All the ROMs do. It's a stock Android option, equals to toggling the "GPS" toggle on in pull-down toggles.
And of course if he didn't have it toggled, he wouldn't see any satellites at all.
Plus, the original post is 2 months old. I believe the OP has already solved the problem or moved on.
Hey everybody
I hope I can get some help from you guys.. I got this issue that I started to get into the running and started to need more of my gps to track my training and Ive noticed this weird behaviour of my gps.. It just wont even search for satellites whenever the 3g is on (you know the alert that says searching for gps).. installed the GPS checker to see if there was no satellites or something but it wont even search for them whenever I have the 3g on.. I found that the GPS works only if I disable the Mobile Data and restart my phone.. So I cant have both at the same time.. the minute I enable the 3g data it stops working and I have all the GPS options checked at the configuration and the wifi 3g assist.. What could be causing this?
Please let me know if some of you guys have some issue like this.. I have JellyBam 9.0.0 cyanogen mod based 10.1 and baseband XXXKI4

If you don't have this issue with a stock ROM, its probably a bug in the Jellybam ROM. Have you done a clean install? Since Jellybam has been banned from XDA, you probably won't get support for that ROM here. Maybe you should try contacting the dev of the ROM on their forum.

I tried the Omega stock V24 and had the exact same issue..
There's a number of GPS 'fixes' on here, I suggest you search for the threads containing those fixes & try some of them.
Hi!
I just want to share my workaround having same problem as this. After configuring my gps.conf as i've posted here: http://forum.xda-developers.com/showthread.php?t=1239713&page=77, all went smoothly and fast GPS lock for just about 5 - 15 sec, even on a cloudy or rainy day. Then last Tuesday morning, as soon as the mobile data got connected it cuts the GPS. In short, GPS & mobile data won't run simultaneously. I ran a series of reboot, shutdown, clean up... then as much as i don't want to, i ended up reflashing/reinstalling everything but to no avail! Now, since everything is fresh w/ my S2, but still had same problem. I now zeroed in the problem to how my mobile data connects. I didn't think of this before because everything works perfectly fine. Anyway, this time i changed the Network mode from "WCDMA only" to "GSM only". Finally! it works! problem solved.
So far as of this writing, both the GPS & mobile data connection are working simulteously. Only drawback are: (1) I can't browse the net using the "GSM only" mode because of the bandwidth limitation, but works ok w/ Waze app. (2) If i switched & connected to mobile data using "WCDMA only" mode, i need to switch again to "GSM only" mode & restart the phone in order for the GPS to works again.
I don't know, but i'm thinking if our telco here has something to do why I had this problem. Maybe they change some configuration... I dunno.

Hi,
I have exactly the same problem. Searching forum and the internet without results.
Last week I spent a lot of time with my SGS2. The problem occurs when gps and mobile internet data are used at the same time, but only when the phone use 3G or H+ standard.
When mobile data are transmitted on E/2G there is no problem at all. The issue with gps is that when I drive car and I'm in one location at the city (every day at the same place) the gps icon disappeared and no navigation at all. This is quite big square around 2x2 km. After I leave the area I have to turn off and on the phone and everything works ok, even when mobile data 3G/H+ are transmitted.
So described problem occurs only at the specific area. I don't know what cause the issue. After next researching I discovered, that gps disapeared ONLY WHEN THE PHONE USES UMTS 2100 MHz. In the service menu I mark only UMTS 900 MHz and the gps works very good. This time mobile data 3G/H+ are used simultaneusly with gps and everything is ok.
So the problem is olny when we are connected to BTS at 2100 MHz and only at the specific area. It seems that some kind of 2100 MHz signal intereferences wiht gps circuit maybe. I'm not a proffesionalist, I only suppose that.
Maybe somebody will find the complete solution with that.
My problem is at the cetral of Poland. I tried a lot of firmwares, modem drivers, gps.conf modifications. Nothing. Zero results.

Hmmm... it seems our telco here has something to do w/ my concern. Today, simultaneously my S2's GPS & 3G/H+ are working perfectly fine. I didn't do any reconfiguration w/ my S2, i just tried to switch how my mobile data connects, from "GSM only" to "WCDMA only".
