Poor gps after root, flash and stock rom - Android Q&A, Help & Troubleshooting

I just noticed this with my note 3 magma note 8 rom and checked with another old phone (galaxy s2) which I have installed cm then installed stock touchwiz back. The GPS cannot lock on to the phone even with GPS apps, clear agps and downloading satellite data. It can see the satellites, but not lock on. For normal use like giving general location, it is fine. But when you navigate with waze or Google maps, it only shows an approximate location. Or do old phones are removed from GPS tracking system to make way for newer devices?
Anyone else noticed this before?

Ask the developer of the rom or check his thread if anyone else is facing the same issue.

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

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.

GPS does not work (tried everything)

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.

[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?

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.

it does also in google maps and the others. i tried that app and it is seeing satellites. where could be the problem, do you have idea?
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).

GPS Problem

I have a GPS problem / question. I'm on Galaxy Note fre3 Hybrid De[Odex] v2.11 but I don't believe this is a ROM issue. I have certain apps that require location services and GPS to be on, example would be the WWE app or even our SBarometer app. If I turn GPS on and enable location services, the apps do not detect that GPS is on and I have no GPS icon in my status bar. If I use GPS Status it's fine. Any ideas? It's not app settings because on my Mega when I open the same apps the GPS icon comes on immediately and the app works properly.
Have you found a fix for this? I am on stock 4.4.2 with root, and I have been having the same GPS issue for several months now. Whenever I use Waze, it's constantly looking for a GPS signal, and MapMyRun will find it and drop it several times while I run making it impossible to track my runs. One other thing I did notice, is when I'm using Waze, if I turn the screen off, it locks on to the GPS. I can tell it's locked on because the voice commands start giving me directions, but when I turn the screen back on, it looses the GPS signal again. I would really like to get this issue fixed. The only other option will be to take it back to Sprint for an exchange.

I too am having a GPS problem. I'm Stock and not rooted with the most recent Sprint OTA (NK4). I've been suffering with this since NH7 came out and no ROMs, stock or otherwise have fixed my problem. Any recommendations on what I should flash? I'm considering doing an Odin Flash of NC5 just to see if that would help.
I have read through this thread, the first thing I would try is to update your PRL and profile. If GPS works on some apps and not on others I'd be willing to bet there's nothing wrong with the device or a stock rom running on it. I would try and contact customer service for the app and see if others are having the same problems with the apps., and see if there is a fix.

Same old gps problem, consideration

Had problem with gps, trying to fix it I changed rom, flashing SlimKat, but choose wrong gapp. So basically I couldn't use google services, but I tried GPS anyway: TTFF 20sec. Cool, it works! So I flashed again rom and correct gapp. Tried again GPS: no way to get a fix, 2 sats after 10min. Somewhere I red about an issue with Galaxy Nexus gps, solved disabling Google location retrieving through wifi/mobile network. So I switched Location Mode from High accuracy to Device only. Fix in 22sec and 9 sats in view. (see attachment)
Please share your consideration about it
note: this behaviour is independent from gps.conf/sirfgps.conf content

I have also tried switching forth and back from GPS only and High accuracy mode. For me it sometimes had an effect, but I'd say that it was purely by chance. After trying out many different modems and apps like FasterFix, I found that changing the GPS.conf worked for me: http://forum.xda-developers.com/galaxy-s2/help/gps-galaxy-s2-i9100-cm11-m7-t2808214#post56014923
