I am using LG Net (P690) and have tried a few available roms but have been facing a constant problem in all of them, that is GPS won't work at all.
Tried GPS Status & Toolbox to clear the a-gps but nothing. It wont even detect the satellites.
Anyone with similar troubles..??
I am on CM7.2.3
First GPS fix may take an awful lot of time even with a-gps and good visibility if your phone does not have well synchronized time.
In case your phone is rooted, you might try fasterfix (available for free from the market) which enables you select physically close NTP server. For me, it helped getting the fix from sometimes more than 10 minutes to a couple of seconds.

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.

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.
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).
Sent from my Legend using xda app-developers app
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.

That's why I´m still using BlaY0´s ROM, I need GPS!
gpsfix works good for me!
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?

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.
