GPS Problem on Kitkat - Moto X Q&A

Hello guys.
Recently (1 month ago) I bought a Motorola XT1058, and the phone is really good. But after I upgraded to Kitkat (not exactly after, I don't know exactly when) I can't get a GPS fix, no matter how many time I wait, or weather conditions or whatever.
That said, I sent my cellphone to Motorola, wait about 20 days to it return, and to my surprise, they say there is NO PROBLEM, hardware-wise. But still, I can't get a position fix on GPS. Using High Precision mode, I get the estimated position, by using WiFi + GSM. But I can't get position using GPS.
So, Motorola say everything is fine hardware-wise, but the GPS simply don't work!
Anyone may help me?
Thanks in advance, and sorry for the bad English.

have you tried factory resetting? have you tried using the app GPS Status to obtain a GPS signal? Not sure if the GPS is and or can be set to specific regions? but maybe that's all the case and would just need changing?

Can you get a fix in airplane mode?

Did the latest firmware fix the GPS issue?

I can't seem to find a straight answer to this so I'm starting a new thread.
With the JF3 firmware the GPS on my 2 phones is often not very accurate or completely loses it's position under what could be considered good conditions for a gps reciever.
Did the new firmware fix this problem?
Please only reply if you actually noticed the problem and can compare it with the new firmware.
Using GPS test is the phone now able to use signals with an snr of lower than 22?
No, it refuses to use GPS with snr under 22, as long as you don't locked them when they were higher. In that case it keeps them downto snr 17, and then drops them.

No and no....
Well that sucks, let's hope it's not a hardware problem
In contrast... I just flashed G3 and my GPS now locks in about 5 seconds.
It doesn't lock below 22... But for me it now doesn't need to.

Mine also locks in a few seconds, but it loses the lock again after a while. Then it locks again, the lock disappear, and so on. Completely useless as navigator.
This is quite worrying, because it suggests more than just a firmware problem.
To those who have flashed and it hasn't worked, some suggest flashing using the repartition option.
But this experience is why I don't want to flash my phone. If there's a hardware error, I can't rightly be taking it back.
Might get a HTC Desire and put the extra few quid up towards a 32 Gig memory card.

on further testing... My phone does use satellites of 19 to 22... But only if it is connected to less than 8 other satellites.
And I don't seem to have a disconnect issue.

Yes the problem isnt that it wont connect but that the thing often thinks you are on an offramp or a road next to the highway you are travelling on because the sinal is too weak/inaccurate. I tested this with 3 different nav programs and get the same result.

Let me get this straight, using GPS Test, you do see orange satellites through regular use?
This is all beginning to make sense now.
Unlike HTC which seems to use a GPS chip that is capable of 12 Satellite fixes, Samsung is using a GPS chip that can only lock onto 8.
I would think therefore that what it is trying to do, is to select the 8 strongest satellite signals which means it's already at a disadvantage, because as soon as you walk behind a tall building, it has to work to try and find and lock onto others. But when you walk past the building it goes back to the other satellites.
This probably explains why everything is jumping around. Because it's not using the weaker satellites in the distance until its too late.
Maybe you guys have the problem of "you hold it wrong"
when I put the phone's face upward, I got only 2-3 satelline locked
stick my phone up => 10 satellites locked and most of them are green
cheers
No - I have installed JG3 and still have the same problems. GPS is practically useless.
Its nice I still have my HTC touc hd - I get a pinpoint lock immediatelly.
Have you tried to use an external bluetooth GPS device ?
Don't think it's possible to use an external gps with android. How do you tell the os or app to use the external one instead?
Sent from my GT-I9000 using XDA App
JG3 seems a lot better for me. Still not perfect, but better than previous versions were I only lost a GPS a couple of times opposed to ALL the damn time !
Well guess I just need to flash my phone and try it myself. I wish Samsung would just release an official update already.

I got the code of this website. Why would i lie? I've had my phone like 2 days and i was sick of getting no gps so i went on the hunt for a fix and there it was.
Google skyhook if you wish.
Anyone else tried playing with the accuracy value in that menu? It seems like it has an effect on locking satellites but I'm not sure.

[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...

Gps problem

Hey i have a question. My droid 3 for some reason doesnt lock on gps. Ive tried to change the settings and still nothing. I downloaded gps status and still nothing. If i cant get it to lock on does verizon give me a replacment for this problem.

Give this app a shot: https://play.google.com/store/apps/details?id=com.Double.FasterFix
@arglmr - let us know if RoadToNever's app helps. I'm trying to find a solution for my (remote at college) daughter's D3 that's having the same problem.
Same here. I found another solution on some forum - install GPS Test from Google play, open Settings, hit Clear AGPS then Update AGPS. Use with airplane mode, and power cycle, if it doesn't do the trick the 1st time.
It didn't work for me, but it might for someone else... Will try fasterfix as soon as I get outdoors.
I am located in Moscow, Russia, but the issue also occurred all over Thailand, so it's not about location.
On my droid 3 I have noticed that as of late my gps has been acting up as well.
Since my droid 1 I have been amazed at how good the gps units in the Motorola fones are. But as of late my fone has been fast to see almost 7 satellites right away but it won't lock on to any.
I use GPS Status (https://play.google.com/store/apps/details?id=com.eclipsim.gpsstatus2&hl=en) and I usually have to cycle the gps off then back on. But once I do that and goto GPS Status it will connect.

D-415 GPS issues

Hello. I just got the D 415 from t-mobile. GPS is working, but not quite as well as it should be. Seems to lock on location and then go away or general flakiness. I have not rooted the phone yet. Are there any tips for settings that could be applied to the phone without rooting?

None that I'm aware of.
Most tweaks are just changing settings in the appropriate file within the devices file system. But root access is needed in order to do so.
I should mention that the GPS is a little flaky on my D415 as well. Might be the norm, dunno...

After owning this phone for three months, I'm worried it might be the antenna, since when I'm in the car, the signal will drop out, and pressing the back side of the phone against my sunroof always make it get its lock back. Might just be one of those issues where the antenna needs line-of-sight to the sky to work :/
In any case, Might be using my old windows phone as my primary nav. device unless there's a confirmed fix.
I have a D405. I used to have a samsung galaxy s3 mini -which was arguably a cheaper device- and had next to no issues recording my cycling rides on strava. On my D405, it won't even pick a GPS signal to begin with. Google maps GPS fix isn't as accurate as the sgs3 mini either, and sometimes well over a 100 meters or more discrepancy. There's another D405 owned by a family member and it's not faring much (if any) better... Thus, I don't think any kind of navigation can be possible with this device, which is a huge let down. Which is a shame because i was enjoying my experience very much with this device until i encountered the crappy GPS...
I have no problems with gps or strava , works very good. No difference with my Garmin.

I think LG used substandard GPS hardware. I have people reporting GPS works great but my own experience, even on stock, it seems flaky to me. GPS wont lock for me if I'm inside but it will outside.
Sent from my LG-D415 using Tapatalk
In some models cars the gps connection is difficult, also some buildings, this has to do with the cage of faraday that shields from a good connection.
So i took my mum's d405 to my cycle ride yesterday and strava picked up a signal and recorded my entire ride just fine. Also, on GPS status & toolbox it will pick up 10 or more satellites out in the open. But my own d405 won't pick up a single satellite. I'm now thinking my d405 has a defective GPS antenna/hardware since both phones are on the same settings. I'll be taking it back to the shop soon.
Yes
I am having tons of GPS issues with my LG D415. It has been driving me crazy (location: Seattle). What's happened:
-Midway through a route, Maps will say "Lost GPS connection"
-Other times it will simply stop tracking the route and lose the position (assuming I am where I was 5 minutes ago); later it will lock into the GPS and begin giving directions again.
I've tried updating Maps. T-Mobile replaced the phone, assuming it was that particular phone that was the problem. But with the new LG D415, I have the same problems. Using GPS Status and GPS Test apps, It seems the phone has a hard time fixing on satellites. Not sure what to do at this point. May try and see if TMobile will take their phone back and try another network.
I worked on the initial deployment of GPS technology to DoD aircraft over 20 years ago and can tell you that the signal is weaker than you can imagine. It is below the noise level so it's not surprising when you can't lock it inside a building. The fact that different phones have different results speaks to the different antennae of the phones. Again, not surprising. Yes, having a clear view of the full sky is the best way to get optimum accuracy/results. What I've seen is that there's an error of about six feet when I use Google maps and my GPS. It could be anything from less than the best hardware resolving the signal to a position to a different earth model inside the phone's GPS hardware to Google maps being less than accurate. I figure that if I can get a position to six feet; I can avoid falling off a cliff by finishing the job with my eyes.

I just purchased 2 phones before I saw this.. I got them through ebay, brand new but with only 14 return. I'm trying to get LG to provide support for mine, have you done anything with yours?
I use GPS constantly, this phone has a weak antenna for GPS.
My phone was picking GPS signals very weakly and could not get a fix to any satellites. I explained my problems in the previous page in detail. The distributor where i live resisted swapping the phone with a new one, and i accepted a main board swap instead, performed under guarantee. They put another (hopefully a new) main board in the phone. But the problem still persists, which is baffling to say the least. Isn't the GPS antenna of this device on the main board ? Even worse still, the device now seems to restart itself randomly. In the ~2 hours i've spent with it after it's been returned to me, it restarted itself 3 times...
If I didn't have one more of the exact same device (which has no problems whatsoever) i would've said i was doing something wrong...
The same night i posted the above message, the phone went full kaput (never go full kaput ). They swapped the mainboard again but the device went bust before even leaving the shop. So there was no option other than to offer a new device. I'm now waiting for my new phone to arrive. Don't buy a phone from a 3rd world country. If this was in the USA or the UK, i know my device would've been swapped for a new one the first time, no questions asked. Choose something you won't have qualms about tossing in the trash if you have to buy.
My girlfriend just bought this phone from T-Mobile and immediately began complaining about GPS quality issues. It looks like there is no fix for this. Should she attempt to return it for a different phone? She has next to no directional skills and relies heavily on GPS.

GPS is flaky at best, even on stock. We all have different results for several builtin devices. Namely the camera as well as GPS. Other than that it's a pretty good device.

Sorry this is a month too late. Have her install GPS Status & Toolbox app and test the device in open terrain. It should easily pick 10+ signals within 20-30 seconds. If it's not, have her take it back for a swap.
GPS problem
I believe the GPS problem is a software issue, when I got the phone it used to get the signal very fast, 6 seconds or so, but now even with Gps fix app, it takes an eternity an then looses very easily, but gps fix even shows 20 or more sats but takes ages to lock the signal.

GPS sensor not working

Hello XDA guys. Your webpage is awesome.
I have a problem witn my Z3C (5833) for a month now and I have tried many things with no success. I hope you can help.
My phone was updated to Lollipop not long ago (May - June to 5.0.2) and in one moment (I cannot tell exactly when) the GPS sensor stopped working. The Wifi and Mobile location work, however the GPS is dead. Phone not unlocked or rooted. Original Stock ROM.
I go to the about phone - Diagnostics and test the GPS.. and it stays as "GPS is starting ... the GPS couldnt be started". When I download GPS test apps, they dont detect a single sattelite. I also tried the *#*#7378423#*#** GPS diagnostics, "purged assistance data", and it keeps on "waiting for location update" eternally
Because of this I wrote to Sony and they answered asking me to do a phone repair from Sony PC Companion. I did the phone repair and the problem was not solved.
Because of this I thought .. hey, maybe Lollipop is the problem. So I unlocked the bootloader and downloaded Emma (Sony recommended flash program for stock ROMs).
Emma downgraded my phone to 4.4.4 (23.0.A.2.93). However I still had the problem.
Next, I enter XDA and downloaded Flash tool. I downloaded one of your stock ROMs: 23.0.1.A.5.77 - Unbranded - Australia (1288-4214) {4.4.4}
I installed it and nothing. Same dead GPS.
So now I have no clue what might be the problem. Maybe the antenna got broken inside? How can I know if its a hardware or software issue?
Any help would be appreciated
Additional data:
Right now I have the 4.4.4 (23.0.A.2.93)

Hi,
I have the same issues. It says since about two months. 23-26 sattelites found, but no signal and no fix. On 4.4.4 was OK, since updating nothing anymore.
I went back to Kitkat but still dead.
Anyone managed to get it back without sending it in??
Same problem...no GPS.anyone with a solution??? New motherboard? Soldering a antenna. Someone's got to have a fix for this problem.

Any updates?
Hello,
I noticed since some time the same problem. I did a quick search on Google, and the problem seems more then usual after one of the official updates by Sony. The problem is discussed on the Sony Xperia Care support forums. All the affected user seems to suffer not from a complete signal outage, but rather from a substantially downgraded performance due to a bad SNR value and poor signal tracking, as can be seen by using the GPS Test app.
Resuming what has been written in the threads, all the following operations seems not to solve the issue:
- factory reset / repair with PC companion
- downgrading to an earlier release
- installing a custom ROM
- returning unit at service
What is annoying is the total disinterest by Sony that seems to ignore the problem, maybe they only want to take time to better understand the problem. If anyone should have news about this please let me know, because the only solution for this issue for now seems to be wating for a solution!
Thank you!
Same problem. Original Kitkat. In May worked excellent. During August I mentioned,it dosn't work. Some photos had changed infos about time and date of creating. On camera disappeared SCENE function in manual mode. When I allowed gps function on camera, gps worked immediately. Unfortunately only once. Camera Blocks gps?
Same problems here...
Hey, same issues here. I think it's just really slow to connect. I've recently sent my phone in for a warranty repair with Vodafone. It came back and was still broken.
Today however... I checked my phone and itw as working again (for about half an hour). Now I'm getting nothing again.
I've tried everything suggested, even down loaded AGPS file etc. But nothing seems to work.
Mega frustrating!!!
the only way for today is replacing motherboard... sony sucks. never again
I just wrote on the sony xperia support forum, somebody talks about a fix they provided for the xperia m series that seems to be affected by the same issue. But for our z series it seems not to be any fix at the moment.
After suceeding the GPS diagnostic test in the settings once, the GPS seems to be fully broken with no tracked satellite at all (before it was at least tracking a few satellites with a very poor SNR, now nothing according to GPS Test app). Repeating the GPS diagnostics now always results in an error. I'll try the warranty return but I'm pretty sure they'll give me a faulty device, as many other here and on the other forum have experienced.
Same problem ... just got the phone days ago.
Any solution ? or do I need to return it ...
I had issues with GPS, could see satellites but no fix on any. after expired warranty I rooted it and used 4 different ROMs, worked on all of them. instant lock on min 6 satellites. I am aware it could be HW issues but this is my experience with this problem.

I'm more and more convinced that this is a SW issue. Sony did something wrong when updating the firmware in August 2015. The fact that the satellites are visible comes in my opinion from the AGPS data, which loads the konwn satellite positions from the Internet. Instead, the problem seems to be the locking of a satellite signal, and it seems that something is disturbing the GPS antenna. If it comes out that this is really the issue, it is very disappointing that Sony didn't do absolutely nothing to solve the issue since last summer.
I'm using CM12.1 nigthlies and since about December/January I have the same problem. So a custom ROM does neither help nor prevent the problem. In addition to that, compass is uncalibrated and I don't get it calibrated again. Really sucks, last year I used the Z3C for lots of outdoor navigation, and suddenly something has happend which makes the device unusable...
I did root with kingroot and changed /etc/system/gps.conf as described in code.google.com/p/android/issues/detail?id=81140#c695
Now my GPS is locking again.
Did not help for me. Currently I don't even get bad fixes, I get no fixes at all. Never ever, even after hours in the open. This sucks.
Hi,
Disabling google maps helped me. Before 0 sats visible, after disabling it locks within seconds.

I had the opposite experience, I had no lock, I was trying everything, then I opened maps and I had lock in under ten seconds.
I wonder if it's a glitch in accepting the google 'we're going to follow your movements' contract. Because until I agreed to that, gps didn't work.
