[Q] Froyo GPS Lock Problem

Ok...so after updating to Froyo my GPS is not working. Not only that, my phone can't seem to find my approximate location even after enabling "Use Wireless networks". I used GPS Status app from the market and I confirmed the phone was seeing several satellites, but it was getting no lock. I had no problem with my GPS with 2.1 aside from losing my location occasionally when I drive through the downtown.
Is anyone else experiencing this issue? I'm running my phone on Rogers network, unlocked and rooted.

You didn't say what version of Froyo you are running but I'd change my modem file and use one of the alternate ones that DocRambone has. There's a thread on this but I find the ZSJPE (Hong Kong) version to be superb (and our company develops an app for the phone that uses GPS for golfers) - very quick, very accurate...

Oh I'm using JK4 from Bell..and kernel version 2.6.32.9....
Edit: Oh and I have also done factory reset/cache wipe...and it's still doing that...I want to see if I can fix this without changing the modem file or anything like that...

I'm having the exact same problem since upgrading to the official 2.2 release from 2.1
EDIT: Bell Galaxy S Vibrant, Unlocked and running on Rogers. Not rooted.

Ok...so I'm a bit relieved to know I'm not the only one out there...From the things I've been reading it doesn't seem to affect phones running on Bell networks..but shouldn't GPS be not affected regardless of the network you're running on? I don't see why it's refusing to get a lock...

I can't believe no one else is having this problem, maybe we're the only ones unlocking??

I was also having this problem. I updated to bell froyo using kies, and am unlocked using rogers. I loaded gps test, set it so it wouldn't shut off the screen, and let it run for about 30 min in a window. Eventually it got solid lock on a couple sats and it now seems a lot snappier to get a lock.

Ok, good news! At least for me anyway... I decided to try keeping my GPS on and let my phone to try and find my location..however long it was going to take. I don't think it took me 30 minutes but it took me good 10 minutes before my GPS found my location. I think the problem was because I'm having trouble getting location information based on my wireless network and updating to Froyo and doing a factory reset must have deleted my satellite schedule. Right now I'm just so glad to find out my GPS isn't broken! :-D You should try the same thing I did.

Thanks Yeria, that sounds like the problem we're having.
I do find that if I give it enough time, It will get a pure GPS lock, but I'm not getting any aGPS (the network based)
That thread you link sounds like the solution, but unfortunately I can't seem to access the file they tell you to modify

I too have GPS problems right after upgrading to official froyo. And it kept getting worse when i tried custom ROM. I tried factory resetting and format all my sd card, cache wipe etc hoping that it will return to normal like when i was in 2.1 elcair but to no avail. I don't know if some bad code was left behind when i did the official upgrade through kies. All i can say is it was working fine when i was at 2.1 then suddenly went bad after 2.2.
By the way, my problem is my GPS lock kept of disconnecting every now and then thus rendering my GPS useless as it kept on displaying my location as "off road" even though i'm on a clear highway with clear and bright skies!

ahh, if I root the phone I can get to
/dbdata/databases/com.google.android.gsf/gservices.db
unfortunately, this phone doesn't have sqlite3 installed!! I need to try and find that
EDIT: Found a copy of sqlite3 and was able to push it to the phone. edited the db as people suggested! I'll have to test it on Monday

Based on what I have found so far, and assuming your aGPS or any other wireless based assistance features are not functioning properly, doing a reset and cache clear will not help with your GPS at all. I have read that the phone will try to download the satellite schedules directly from GPS satellites if you're using purely satellite based GPS option. It'll be slow so it will take longer to get a lock and that's why phone will use other means to shorten the lock time. Once the schedule is downloaded, they said there shouldn't be any problem until the schedule expires, at which point you will have to download the schedule again.
I think the reason you're losing lock frequently might be because your phone doesn't have a clear view of the sky..? I used my phone GPS to drive around Toronto, Vaughan and Mississauga last night for at least 4+ hours, and I did not have any problem.

So, I tested today after updating the db.... no agps still..
Anyone else still.having issues with agps?
GPS works, just no agps since 2.2

This is why I unfortunately have to use an old Tom Tom GPS!

i'm having this problem too. i finally got it picking up quickly on 2.1 but once i updated i haven't been able to ever get a solid lock. has anyone found a solution yet??

Now that my wireless location service is kind of working I thought aGPS should also naturally work but I guess not... My GPS takes a pretty long time to start up and I haven't found any fix for this..
It's funny because I didn't really have any problem with my GPS with 2.1 but now I do with 2.2...

[Q] GPS AOKP Help

Okay guys, so I know that this question has been done to death but I really can't find anything about it.
I recently installed the most recent July 9th version of AOKP. Everything works fine except for my gps.
I have done "• If your GPS doesn't work after flashing, fastboot back to stock ICS, then flash this is CWM." this step in the AOKP ROM thread multiple times.
When I'm on stock, obviously the GPS works fine and can pick up satellites ect. However, when I run the GPS status app or the GPS test app now, it tells me the GPS is on, and the gps icon blinks in the status bar but no satellites are found. I have tried resetting GPS and getting Xtra data in the GPS status app. In the GPS test app, it tells me the GPS is on but the light is yellow in the box that says GPS status. I also have tried clearing and updating AGPS in this app.
Any ideas?

have the same questions , i use the CM and MIUI ,the GPS can not work ,but use the 4.1.1 the GPS works fine....
then i flashed the CM ang miui again ,the GPS can not work again ...
can not find a good way to solve it.

What you get is not really GPS data... If you get it only after flashing gapps, it indicates it is Google location service based on mobile network or WiFi...

I was outside when I was testing it.
It was the first time I needed GPS since I started using AOKP. I was fiddling with it in the parking lot for a while. When it didn't work, I went home and did what I said above and then sat in my car and tried to get it to work.

when i tested the GPS, the wifi and gprs were both off. Only the GPS is on .

Some of the gps files were tweaked in the past week or so (dev-team side). Later today I'll be building a new PAC with those updated files. If GPS breaks I'll see if I can't find a fix then. Might need a new GPS lib or some tweaking to the repos....can't really say anything concrete right now.

Bumping this thread again to see if anyone who has had this problem can help me. Just went back to stock after wiping everything. Made sure gps worked. Then I factory reset, cleared the two caches, and flashed AOKP and GAPPS.
GPS still does not work. No satellites picked up, just constant blinking up in the status bar.

[Q] GPS Sporadic after 4.3 update

I always have raved on how great the GPS is on my S4. It will lock onto satellites with 10' accuracy in the house. It was always spot on and never gave me any issues. That was until the 4.3 update. (I am not positive this was the reason - but it is around that time).
I am a runner so I use my phone 3-4 days a week to track my run 3-10 miles each time out. Before it was always perfect. Now it will lock on and track for a various amount of time.. from a few minutes to 15 minutes - but it will eventually just stop working. If I turn on the phone to look, the GPS icon at the top is not there, and the app does not know it lost gps signal. I can touch the screen and then the gps icon reappears, blinks, reconnects and all is good. I turn off the screen and go about my run and it will work for some period of time and then off again.
It "seems" like to me some app is using the gps and then not playing friendly and turning it off for the other apps. I don't know if that is what is happening but it seems that way.
I get the same results no matter if I use Google Maps, Waze, Runkeeper, or GPS Test... so it is not application issue persay.
I restored to factory and installed only what I need to run (Runkeeper and Google Play music) and it worked without a hitch for the entire 6 mile run. Great! Fixed! So I re-installed my apps and now it is doing the same thing again. So that seems to indicate another app not playing nice like I mentioned above. So I uninstalled any apps that I thought might be an issue and it is still there. So I fear it might be one of the ATT bloatware apps that I cannot uninstall.
Before I undertake the very tedious task of restoring to factory, running 6 miles, installing 1 app, running 6 miles, repeat --- until I find the culprit - I was hoping someone might no a quicker solution?
Thanks!

Are you sure it's not staying connected but not displaying the icon? Ie, if the app hasn't realised the connection has dropped, maybe that's because the connection hasn't dropped, just the icon has? In tech terms, to solve a problem you must first find it by isolating the cause, which would be the tedious task you're referring to.
Even then, it is possible it's a hardware or firmware issue, so a factory reset still might not fix it. Have you tried an app like this? It ill set your NTP Server without searching for it so that it connects quicker, maybe (I'm not sure) it will be able to keep it connected to that server.
Do you have CWM? You could flash a different ROM.

I can confirm this problem. It is intermittent. GPS loses the location fix. I had a similar problem with certain Motorola Attic ROMs that had something to do with a conflict with the "Use Wireless Networks" setting. I'm those ROMs, I could turn that setting off, and GPS would work fine. That workaround doesn't work for this ROM. I only mention it to help rule some things out. I thought that it worked fine right after I updated, but I may not have used the GPS much our maybe I just didn't notice. Yesterday, it was barely usable. I remember that epinter, in the Atrix 4g forums, had a tool that reset some GPS settings. I'm see if I can find it and test it. I will report back.
Update: Today, GPS works perfectly fine. Seems to be intermittent.

Still having the issue. Reset my phone to factory again this time taking the extra step to format the SD card to just in case. By the way - I am running stock AT&T 4.3. This time when I reset I did not connect to the WiFi so it would not automatically install / update any apps.
I then added only 2 apps - Runkeeper and Play Music and went for a run. The GPS tracked perfectly for a 5 mile run.
I then installed GPS test and let it run for an hour or so. It never lost connection.
So I updated GMAIL. Repeat GPS Test.
Updated Hangouts. Repeat GPS Test.
And so on.. finally after about the 10th app it failed. The last app I had installed was Facebook.
So uninstalled. Failed again. Uninstalled the previous app to that which I think was My Fitness Pal.
It seemed better - it would go hours before failing... and then only seemed to fail when a phone call came in. So thought I could live with that.
So went to the gym and to test it I used Google Maps to navigate. Terrible! Would not work for more than a mile. I finally gave up.
When I say it is not working - I mean the GPS says it is on. The GPS Test app says the GPS is on. But the icon at top goes away and Google Maps says "GPS Signal Lost." In my Run Keeper app - same thing - icon goes away and no more mileage is recorded. If I turn on the phone, open Runkeeper - it then restarts the GPS and all is good for another few feet or maybe a mile and then it does it again.
I tried turning off the Use Wifi for GPS option and that has not helped. Thanks for the suggestion though - you gave me hope.
I have have been a software developer for 20 years and this just smells like buggy code somewhere and not a hardware issue. Either something to do with the new OS update from ATT (but why is no one else complaining) or some combination of apps I use. Runkeeper. My Pebble. Something. But it is driving me nuts. The GPS really is the main app I use on this phone... so it is making for a really expensive mistake at this point and I hate to admit that since I love Samsung and Android.

I should have updated my status again. The problem is intermittent, but it happens often. Like you, I am fairly certain that the ML2 update brought bugs with it. My GPS always worked perfectly before that. Now, even when it does work, it doesn't work well. The fix is jumpy and slow to update. My guess is that others also have the problem, and they don't use their GPS often enough to notice or care. I bet that Samsung is aware of it, but so many people had problems installing the last update that they will not be so quick to provide an update that doesn't affect many people. I guess a better way to put it is that Samsung probably doesn't want to take a chance that a small update might break more than it fixes.

I also have same GPS issue since 4.3 , same issues note 3 is having actually if I plug my active in while GPS is on it will stop working and when switching data network types it will lose GPS signal

Convinced it is the 4.3 ATT Active update now after repeated and very controlled resetting and testing.
Frustrating and makes my phone fairly useless to me for my main purposes. Today during a 7 mile run - it lost connection at least a half a dozen times. I have to run with the phone in my hand and restart the gps constantly.

Some people said they had success using Odin to flash the MF1 modem bin file. The thread discusses it here: http://forum.xda-developers.com/showthread.php?t=2691264
However, this did not fix my issues with GPS unfortunately, but thought maybe I'd post it in case it helps someone else.

So it appears that it is, as suggested, the radio that causes this issue.
A "workaround" for using the GPS is to put the phone into airplane mode (turning off the Radio and WiFi) fixes the GPS 100% in my testing.
However this is not a real fix for real use of the GPS to navigate since you have no access to data.
It appears these are the circumstances that cause my GPS to drop:
- Cell radio changes towers (which happens a lot in my remote area)
- WiFi changes antennas
- Phone is plugged in or unplugged
- A phone call is received.
So yeah - as long as your don't use your phone as a telephone - you are grand!
The new HTC One is looking mighty nice to me right now. First non Samsung component (phone, laptop, TV, etc) that I have considered in years...

It's weird that even in airplane mode my Active won't get a gps signal. Used a few apps to test as well: GPS Status, FasterGPS, GPS test, and all say no satellites in site.

I was getting GPS issues for quite some time, until I tightened the screws at the back of my case. It was supposed to be a fix for the S3 but it worked fine on my S4 as well.
Hope this helps

I've tried tightening up the screws a bit, which they did, but still no GPS for me. Going to do a backup and another full wipe and restore.

AT&T fixed my phone
I too had the GPS signal lost issue after the 4.3 update on my S4 active on AT&T. I called AT&T yesterday and they advised me they were aware of the issue. Their instruction was to take my phone to Best Buy where they have a "Samsung Solutions / Experience" dept / kiosk. So I did. They flashed my phone to 4.4.2. I am happy to report that all GPS problems are resolved. I drove for over an hour using Google Maps this AM with no problem at all.
GPS is a big deal for me too. I drive in a lot of unfamiliar towns. I'm also a sportsman and spend a lot of time in unfamiliar woods. I rely on my phone to allow me to retrace my steps back if need be. I also use it to set waypoints and mark areas for possible future hunts. The woods look a lot different at night then during the day. So I rely on the phone to help navigate off the beaten trail and get to my tree stand. GPS failures are not an option. Pure and simple. I can get out of the woods with a compass - but I may not find my tree stand in the dark without my phone.
I don't know about rooting this ROM, etc as I don't have need to root my phones. But it did fix the GPS issue and the phone seems a little faster with battery battery life too. YMMV.

Thanks for your post! Did you l lose any data with the update to 4.4.2?
I have the same exact problem with my S4 active, definitely a software issue. For a while I used the airplane mode work-around which was great, until a recent update to Google Maps causes maps to crash when airplane mode is on, so now I'm back to having no navigation. I'm frustrated that AT&T has dragged their feet on getting an update out to the public. They must have zero QA to let a bug this obvious get into the public. I wonder when they'll push 4.4.2 out as a regular update?

No I did not lose any data or apps. I have no complaints. Phone is working great. I'll never accept another update OTA though - I don't care if I have to root to avoid them.

I got the 4.4.2 over the air update, and it fixed my GPS problems. No new problems.

Try this app https://play.google.com/store/apps/...fix+app&pcampaignid=APPU_88iwU9unK8SvyASZj4FA make sure you're in a clear sky and let it search. If not then you should return your phone to AT&T and get a replacement. I am running firekat (which is the twin brother of Urdroid) and it locks in no time.

I tried all these apps but none of them worked. I used to have working GPS on S5 ROM, so I did a Nandroid backup of my current setup, wiped everything, flashed S5 ROM, got a GPS lock a couple of times, reboot in recovery, restore my Nandroid backup.
Hope this helps...

5.1.1 killed my GPS

Happy stock user here using only official Sony upgrades (non rooted) on my Z3C. 5.1.1 arrived 3 days ago, I did a factory reset after the upgrade and woah, suddenly I have no more clean GPS locks anymore. It was working perfectly and now it locks in about 5% of all attempts and even then loses fix in a minute or so.
Tried to search around, clean agps data, refresh agps data, double check location services and what not, nothing helped so far. I just arrived to Greece with my family for vacation and had to find our apartment with a paper map - a pretty amusing experience anyway, not counting my wife's harsh comments..
Should anyone have an idea to counter this problem, it's most welcome. Should anyone have a similar experience with the 5.1.1 upgrade, this would be comforting at least..
Thanks and enjoy an otherwise brilliant smooth upgrade!

I seem to experience this as well. I regularly check the weather (several times per day) and I can hardly find my position, so I'll have to resort to manually type in my location (which doesn't provide me with the precise location prognose that I'm looking for).

same here, 1weather really struggles to locate my phone

Just by chance, are you also EU users? I thought maybe the 5.1.1 update defaults to some US settings and this might cause the problem.
What I tried already and did not help (to save you some time):
- removed Google backup and do another factory reset to avoid restoring some backed up settings which might be the cause
- various gps apps from play store which claim to fix/reset gps, with or without rebooting between attempts
- resetting gps settings from the service menu accessible via codes from the dialler
I'll also try to achieve root and install custom rooms from xda once I'm back from my holiday (assuming that I'll find the airport with a paper map )

Have you tried GPS Status from the store and downloading the A-GPS data??

Yes, of course, many times with many different apps. Made no difference at all..

No problem with gps in Ingress or different maps while driving around in Denmark.

I'll also try to achieve root and install custom rooms from xda once I'm back from my holiday (assuming that I'll find the airport with a paper map )

Your GPS hardware might be broken...

Do you think yours is broken as well? Would there be a way to get certain about it?

Mine isn't broken, I can still get locks. It just takes it sweet time most of the time.
Yes, go into the settings, then location and enable "device only" (only gps). Then try to get a lock somewhere. If that doesn't work, then your GPS is broken.

See the attachment.. it seems I can get a lock too! It happened after 10-12 minutes of searching after clearing A-GPS data and after 5-10 seconds (!) it loses it and often also falls back to having exactly 0 satellites in both "in view" and "in use" (as if turning GPS off completely and restarting seeking from scratch).
I assume it's rather a software than a hardware problem then, or..?

I have a similar problem with andosm app. If I let the app open on the background with my screen off, when I turn the screen on I have a precise location with 5 to 10 GPS fix but 5 seconds later the GPS fix drop to 0 and have to wait 30 second to get my location back.

After upgrading to 5.1.1 my GPS stopped working. I was unable to obtain a lock in Google Maps (as well as the Service Menu).
I downgraded to 5.0.2 but the situation did not improve.
I ended up sending my phone in for repairs (under warranty). So far the seller has confirmed that the "GPS is not functioning as expected" and has sent it to the repair centre.
Hopefully I'll get it back with a working GPS eventually!

Have you tried with kk before updating to lp again? If it doesn't work there either it might be hardware related.

No, I did not - I was in a rush unfortunately.

I have had the exact same issue since upgrading to 5.1.1. I was convinced my GPS hardware was broken as I had tried all of the possible fixes I could think of (a-gps clearing / factory reset etc etc), I have sent mine for repair under my insurance policy, but they have already sent it back once without being able to fix. I too am getting GPS fix eventually, but it is very weak and I lose lock after 5-10 seconds, especially when in motion (in a car).
I am hoping this time that they just replace the phone. Will reply here if that resolves the issue.
Would be interesting to see if anyone was able to resolve this through rooting/custom ROM...

Also it looks like there are others that are having the same issues (possibly since before 5.1.1 as well):
I cant post the url, but there is a forum on the sony website if you google for it.
it seems strange that this doesn't seem to affect everyone...

I'm not sure how it is for others but I most often get a fix now in a few minutes (without changing anything on the software or hardware side!) and it's so-so stable, losing it only 1-2 times per minute So it's very far from perfect but much better than a month ago..
I would _love_ to know what the hell is going on here. If nothing changed on my phone's side, I'm about to believe that it's a central issue..

Same issue here: Xperia Compact Z1
Upgraded last week and had no GPS since. GPS test receives no lock
Am running stock rom - Upgraded from 5.0.4 (i think) to 5.1.1
This is definitely 5.1.1 as had no issues before this. Bit worried that downgrading isn't helping anyone.. going to do some more digging and see if there is any fix for my out of warranty handset
