Hi, I'm writing you now because I feel desesparated.
I've searched many forums included this but I can't solve my GPS Signal Issue. My phone won't get any gps signal from Waze, CoPilot, Google Nav... I've tried to fix the GPS with "Faster Fix" (I've chosen the right country) and even "GPS Status" and "GPS Fix" but none of them solved the problem.
I remember the GPS to be working before but it may be related to my rom or modem.
I'm running my Galaxy S2 with the latest NEATROM 4.9 with the Philz Kernel that comes with it. (Gps doesn't work with Neatrom 4.8 as well)
I really need help, I hope its not a hardware problem! Perhaps I have to flash another modem?
Thanks a lot :crying:
I don't think modem and gps are related mate. Try flashing a stock rom first.

Try this thread. But yeah, back to stock to test as Neo said. Correct, modem has nothing to do with GPS beyond the obvious - if you're using A-GPS then having good mobile network connectivity will enable you to get a faster/more accurate fix (particularly in situations where non-assisted GPS won't work well - inner city with lots of tall buildings/poor line of sight to satellites). Changing modems won't help you get a better fix with 'ordinary'/non-network assisted GPS.
Edit - Also, the following has always solved any (minor in my case, I've never had major dramas with GPS) problems I've ever had:
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). This has 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 the process as required.

I quite don't understand the steps in the thread you gave me, the explainations aren't clear. I don't even find the gps.conf file in my sd card...
The tip you gave doesn't work as well.
I'm going to opt out for a stock rom, but I remember my gps to be working on a custom rom.
I'll try to reply as fast as I can with the stock rom tested
I don't think I'm going to install a Stock rom, I've tried the GPS with the latest Resurrection Remix rom and it locks a satellite in 5 minutes' time.
So I know that the problem is not hardware related and no need to try a stock rom. The issue is to be found in the way my gps in configurated. It takes too much time to lock my position.
I may go back to Neatrom 4.9 and try to solve the issue from it

I didn't mean MistahBungle's explainations. I tried what he told me to do but in vain. I meant the instructions in the link he gave me, it's quite complicated... And if you have totally understood them, feel free to explain me
EDIT : I've flashed StaticNav 1.1 and his GPS Exynos file as well, and still the same

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.
I have a problem with my GPS. Since 4.2.2 (on different roms that I've tried) it takes a long time to get a fix. On earlier roms this wasn't a problem and I would get a fix in seconds. I use the app faster GPS to write the appropriate .conf. I read about someone else having the same problem. Is there a way to fix this? Maybe flashing another modem? If so what modem would be recommended for The Netherlands?
Would love some help with this

Do you use the correct time server configuration?
I mean did you install faster fix, and change the ntp server to your country's ntp?

Good suggestion. Not only that, @OP try the following:-
Once you've installed GPS Status, go outside to a place that has clear line of sight in as many directions as possible. Turn data & GPS on. Open GPS Status & go into tools/manage AGPS state. Hit reset to clear the data, then hit download to allow it to download fresh ephemeris data. Then turn data off & allow it to 'learn' where the satellites are based on that ephemeris data (could take up to 10 minutes the first time).
Once you've got a good fix with plenty of satellites, you're done. You should then get a fix fairly quickly (it will be lightning quick if you have data or wifi on) for a minimum of a couple of days (and potentially up to two weeks). Once getting a fix becomes unbearably slow, repeat this process (Worth it if GPS is something you use a lot).
This is something that has always worked for me.

I flashed another 4.2.2 ROM (Mysterious ROM) and the problem is gone. I get a fix pretty fast and it stays fixed whenever I use it for traveling. I still use Faster GPS to write the appropriate .conf file.

GPS-Fix
HI65a9[/url]
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,
I am on Stock JB kernel with Hunami Moonwalker 5.5...Xperia P
My GPS always shows searching for GPS .... is that expected? Basic question is data connection needed for GPS to work?
Even I turn on Wifi it shows the same message... Searching for GPS...
Please tell me whats wrong here...
I have the same problem with Xperia U, but I did not tested it on stock rom.
With a stock rom it works on your xperia P ?

No it's not like that, when you switch on GPS, the GPS only receives the signal from at least 3 satellites, in case of A-GPS at least 2, the fourth position lock should be achieved from the earth's sphere. It just gives the fix, not the details. If you want to locate yourself using your mobile you must need 'data connection' to download such details, after that only the mobile can fix your position based on the data it got from net and the gps time signals received from the sats. In case of pre-loaded maps it is possible to show your location without data, even though you need a current positions of satellites to calculate your position...
To be short, you need to enable your data connection for your first fix, theoretically after that you can switch off your mobile data until few days(may be from 2 days to a week)
And try it from a roof top, not covered by many tall buildings. GPS may not work in many areas, sometimes even in cities(some places).
Enable wifi, Google has a spatial database for almost all wifi routers in the world, this will makes the possibility of positioning twice.
If you don't get a GPS fix, even after these testings, then you can conclude the problem in your mobile. After that we can dig whether it is a s/w bug or h/w bug...

It means you may have problem with your ROM or Kernel installation. No body in MoonWalker ROM posted this bug.
Try reflashing the ROM after flashing stock FW 6.2.A.1.100.
If you are in unlocked boot loader, try some other kernels.
I'm having the same problem with Xperia P CM11 nightly 11 by percy_g2. At the forum it says that GPS works A-GPS does not but my GPS does not work and always searches for location. Please tell a fix!
Thank You!
On my phone I lose the GPS Icon in the Notification drawer and I lose GPS signal. then if I turn off and back on GPS using the quick link it comes back. Is this just my phone?
Solved the problem by resetting to factory. Not too painful with backups. I did see this in another phone at the AT&T store so I don't feel alone here, beside the fact that NO ONE WOULD RESPOND!! ;|
I have exact same problem. Have to then off and on while using navigation on my Samsung Galaxy Mega 6.3. But I don't think resetting to factory will solve problem as the problem seem to be with other Galaxy Mega devicesas well. Maybe a software update or some kind of Gps fix would help. Still looking for solutions.
I have been having this issue for awhile now. I have tried clearing the cache, and factory resetting the phone. I got the mega 6.3 to have a bigger screen for GPS for my job, as I am a Delivery Driver, but its more pain then its worth turning GPS Off/On again every 2 - 5min.
What I really don't understand... is my GPS Fix time is very fast (faster then my old SGS3), but then the GPS Icon in the status bar just turns off, and I have to reset it.
There is also no constant in when it turns off... Just today... my first two deliveries... had to reset it about 30 times... but to my 3rd.... didn't have to reset it at all... then back to having to reset it constantly.
It would be easier to explain if there was a pattern... but there isnt.
This has been tested in Google Navigation, Mapfactor: GPS Navigation, and Sygic GPS Navigation & Maps... All do the same thing.
Also does this with GPS Status & Toolbox Running.
Its like gps is being forced off.
So.... Question for anyone who DID have problems with GPS, but fixed it after a factory reset:
Have you disabled AT&T Software? Thats the only thing I have done both times. I hate the AT&T Bloatware they include with all their phones that love to run in the background.
Anyone else have any idea of what I can try to correct this problem
---------- Post added at 05:49 PM ---------- Previous post was at 05:42 PM ----------
Did A test while writing my last reply.
I turned on navigation... and I am not loosing GPS... but... I also am not moving...
So... So far... the only factor in me loosing GPS..... is when I am moving...
This has me confused...
Could it be... for some odd reason... the google location permissions?
I have the same problem....I turn on GPS Test (from the Play Store) and Nav picks GPS up right away. Now, I leave GPS Test running in the background and it seems to help.
GPS sucks
I had this problem and I have seen the power connect version of it come and go. Currently the power connection event does not kill my GPS but many other events do. That being said I have seen this same issue on a Note 3. I played with a number of devices at the AT&T store and several have this issue. I did find an AT&T user forum about the GPS issue on the Note 3 and there are comments on there that the 4.4 update fixed the issue. So I am holding my breath for the Mega 4.4 update to see if that solves the problem too. 'Everyone inhale and hold.......'
My problem is I cannot wait... I guess I will have to use PDAnet to give my Broken Screen SGS3 a connection... and use GPS on her for work... its such a hassle. Why does it always seem to be AT&T Phones
