I am on the brain's rom which is based on ics stock. I have a problem that most of you should be facing. My gps works great at first time I use it. It sees 8-12 satellites and locks quickly using 4-6 of them. The problem starts after I finish using it, 30 minutes later let's say. Phone enters deep sleep while I don't use it. So when I open an app that uses gps, this time gps sees 12 satellites again, but no matter what I do or how much I wait, it doesn't lock. Having wifi on makes no difference. Either clearing agps data and downloading it again, using gps status or similar apps. What does help is rebooting or switching flight mode on and off. It is like agps data or gps cache distracts gps instead of helping it. I would call it a gps deep sleep of death bug. Tweaking gps.conf file doesn't make a difference after deep sleep of death bug is encountered. I wonder if something is wrong with gps lib files.
Does anyone else have this issue or is it just me?
Have you managed to find a walkaround?
For other devices the fix was switching to an older radio or a hybrid one or changing gps lib files.
Is there a chance it is kernel related?
If anyone can help, please do.
Thank you everyone.

When using any version of the CM7 ie... PUR3AO5PTH3ORY V1.2.2X [AOSP/CM7] I can't get an accurate GPS lock without using WIFI. I have been all through this forum and tried all suggestions and my location is still off by a mile or so unless I use WIFI then it is right on. I have not had this problem with other ROMs so I know it is something in the ROM and not my phone. I love speed of the CM7 ROMs and the simplicity, no bloatware, but I do need a functional accurate GPS without WIFI on my phone for my job. I hope this gets fixed soon as I flash every CM7 update I see hoping this problem gets fixed. For some reason I am not allowed to post in the ROM Developers section so I hope this gets to the right people to make this fix. I have been flashing ROMs for almost 2 years now and have helped a lot of people with ROM related issues but I can't seem to figure this problem out. Please HELP!!
Have you tried the Sense rom fix yet? And as a new user, you must have more than give posts before you can post in the development section.

I concur with the GPS fix that has been posted in the thread on the development forum. I had the same issue until I tried the GPS fix.
THE GPS FIX:
-Download DroidTh3ory's 'Special' sense build, stripped down and built for this purpose alone, posted at the bottom: http://forum.xda-developers.com/showpost.php?p=16305878&postcount=1
-Turn on GPS
-Boot into Recovery
-Nandroid Backup your AOSP
-Flash Th3ory's Special build
-Reboot
-Turn on Location and Open Maps
-Wait for GPS lock. With a GPS lock, boot into recovery.
-Restore your AOSP Nandroid
-Reboot
-???
-Profit!!!
I've been having an issue where it thinks I am in Lithuania or Oklahoma instead of Maryland where I am. Seems to be a known issue with CM7, and sadly, this GPS fix only fixes the inability to get any GPS not inaccurate GPS like some of us are experiencing. I heard that turning off Mock Locations has helped some people, but it didn't do anything for me.
I have problem with my papago x5.. i dunno why it taking at least 15mins or more to locate my current location. that problem really annoying me because like we know, running papago consume much batter and drain fast.. help me someone how to fix it..
There are gps fix on devel forum, you can try to install maybe fix your gps. Another way turn on default location using mobile data.
On papago, look how many gps sat your ace have been locked on.

thx.. i will try to find that gps fix..
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

I had the issue on stock Rom 4.0.4 before I flashed aokp build 3. But maybe I'll try a different Kernel then... just to make sure that this is not the problem

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.
Hey Guys,
Loving my galaxy s3 however something strange is now happening. I used to live in Brisbane and recently moved to Sydney, whilst I was in Brisbane I often used the GPS and google maps navigation (google navigation whatever you want to call it ) and it performed amazing! it locked onto location instantly and would guide me and track my position superbly.
Now I've been in Sydney for 3 days, and I tried to use the navigation several times and it was terrible! It would take a minute or two to lock onto my position but would still be fairly innacurate and would not engage the navigation, just sat in that screen where it is zoomed out and roughly shows the route to take, sometimes it would engage into the navigation but then would stop tracking me and just say it lost GPS location.
Has anyone experienced this problem? or know what I can do to fix it!! Thanks
Couple of suggestions:
Have you changed your Google location? Whenever I've changed ROM's I get asked to let Google use my location - maybe there is something in the Google set up that still thinks you are in Brisbane and has to keep scanning for your new location?
Have you got the map for Sydney - I know you can get maps on your phone but maybe only your home location is auto-downloaded, so you get a zoomed out version for other places? Maybe go into the Maps app and select Sydney and see if it brings down a more detailed version?
Maybe check for Maps/Navigation updates? I got a Maps one a few days back.
I hope this helps - not sure at all if any of them are applicable but it is what I'd be checking...
For the google location, I sort of reset it, I turned it off (the option to let google use your location) and turned it back on. Not sure what else you can do in that department.
Ive got the map for sydney and my maps and navigation are up to date! Thanks for the suggestions but, its just really frustrating as it used to work so well
Use either GPS test or GPS status to see how well your GPS is working. Both are available free in market. They will also download agps data to help with a faster fix.
Check that you do have satellites switched on in settings.
If you are rooted you could try the wildfire agps patch. I think it is posted in the development thread.

thanks for the suggestion! just downloaded GPS status and one of the reviewers had the same issue that was resolved by clearing and downloading agps data (just like you mentioned). So will try tonight and hopefully problems will be gone, thanks!

That method always worked for me on the S2 when I was in a different location. Takes seconds to reload the new data.

I can't really help but my s3 in sydney has almost instant lock, except when in a tunnel.
By a strange quirk of fate I have just experienced the same issue that you faced.
After a lot of frustration I found a simple fix.
Turn off GPS and other location settings in main settings, power of and reboot. Switch everything back on in settings and all should be well again.
Hope this, belatedly, helps.

If you are on a custom ROM then the first line of the GPS.conf file in system/etc will be set to "north-america.pool.ntp.org". Change the "north-america" part to "au" and restart. Then reset/redownload gaps data.using GPS status. Hope this helps.
Hey Guys I have 27 satellites and my phone can't lock on to any of them.
I am rooted on the stock ROM. Can anyone give me any pointers?
Are you inside a building or house. Gps doesnt always lock when in a building. Could also be that your rooted. Are you using a rom other than stock. Sometimes these roms have issues working with wifi, gps and other hardware.
Sent from my SCH-I545 using Tapatalk 2
I am in a building, but it is weird how it says 27 sats but I can't lock.. seems like software issue. I am on the stock ROM.
Myself and others have had this issue. Try the following: when in the GPS related ap, pull down the notification bar and cycle the GPS off and on. With mine (and others) GPS will lock almost instantly after returning to the ap.
/found in another thread that this appears to be software related. I can confirm this as I had the problem until I uninstalled GPS Test. Check any ap you've installed related to the GPS and see if the error is resolved.
So it turns out mine works great outside my job and doesn't work at all inside my job... I never had that issue on my old phones.. but w.e... This thread can be deleted.
Thanks guys,
