[Q] No GPS fix on Lollipop?

I have upgraded to L using Walter's method. Everything is pretty much good except that I can no longer get a GPS fix in any app I use. I can see plenty of satellites (upwards of 21), but will not get a fix...seemingly ever (I let it try on a 2 hour drive). To clarify, GPS worked quite well on 4.x.
I've tried a few workarounds such as:
GPS settings to get assist data
secret code to rebuild nvm or something like that
turning on and off high accuracy
performed the hardware hack mentioned in the general forum
I haven't tried a factory reset yet, and I'd like to avoid it if possible. Just curious as I've seen this problem detailed for several devices and networks, but no real solutions.
Thanks in advance.

Quick question. You do the stock or rooted OC1 http://forum.xda-developers.com/note-3-att/general/update-procedure-lollipop-5-0-oc1-t3063760 ? Think about flashing it myself.

The rooted from post 2. Everything else seems to be good.

Make sure you have oc1 modem. I play ingress and have no GPS issues

There were 2 many reasons why it is very slow to get GPS lock but one problem that I know 100% causes the GPS to lock slowly and not at all because of the aluminium back case that I was using on my galaxy note 3. I tested the GPS status toolbox with back case aluminium and sometimes the GPS lock took long time to fix and sometimes it did not lock at all! But supprisingly, when I remove the back case cover, I don't have that problem anymore. So, check if you have the back case aluminium. Something is interfering with the GPS signal. Now my note 3 is naked without back case but I'm happy this solved the issue. As I said this is one of the problem that caused the GPS lock issue. Perhaps there are more...

Tried everything including factory reset, still no luck
I tried almost everything as OP and did a Factroy reset. Still have the same issue, GPS cant get lock in. It works flawlessly before, start to having this issue after updating to lollipop, dont remember if it happened just after or not.
Is any other possible method to fix this?
Thanks,

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)

If the issue still exist with different firmware i guess its a hardware failure.

In sony it says its near the headphones plug. No more details.

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.

Same problem and even tried to update to Android 6.0 with Marshmallow and still no GPS. 23-26 sattelites found, but no signal and no fix.

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.

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 )

Yes, I'm Swedish.

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'm back from my holiday. Downgraded to 4.4.4, rooted my phone installed TWRP and poured the custom rom 23.4.A.0.546 SLiM 2.6 on it. Still no GPS lock in Waze or any other location app..

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...
---------- Post added at 04:15 PM ---------- Previous post was at 04:03 PM ----------
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

gps fix problems

Dear All,
I have been a LP 5.1.1 user since the beginning and I didn't change anything but all of a sudden I can't use Google Maps as I don't get a fix. I used GPS test and also no fix.
I had this problem before and did some fiddling and got it working again. But I forgot what I exactly did. But I don't think its a hardware failure but a software glitch.
Hopefully somebody here with same problems.

hy, try to update Google play app. or one more thing, uninstall completely Google play app, reboot the device, and install it again.

I would love to try your suggestion but could you please be more specific? Which app are you talking about the playstore app or the Google app services app? How can I Uninstall such apps on a stock lollipop 5.1.1? I have never rooted my phone or whatsoever a real strange problem that showed up out of the blue.

Did a whole f*cking reflash with stock android (wiped all the data with flashtool) 5.1.1. but it didn't resolve the problem... time for a new phone.

I think this is not software problem. It was happened when I flashed to 5.0. I think flashing from 4.** to 5.0 killed my gps. After tried all kind of solutions in sent my phone to Sony service centre. The changed my motherboard without any questions. And my warranty was extended to +2 years. I think Sony know exactly what is problem. And my opinion is that is hardware problem. I also think this problem is just with first generation of z3c. My friends bought this phone later with android 5.** don't have any problems.

Help! P20 Pro GPS doesn't work after update

Hi I just update my P20 Pro to EMUI 9.0.0.178 and my GPS stops working, everytime I use Google Map it says "searching for GPS" and leaves me a grey dot. It's becoming a headache since I heavily rely on it for driving. Does anyone have the same problem with their phone? I tried restarting it, toggling location, reloading the app, still the same problem.
please help.

i have same problem

Mines was jumping all over the place today. Is there a way to calibrate the compass?

I try to restart the phone everytime this problem shows up, and it seems to solve the problem. But it's annoying knowing I have to restart it everytime to make it work...

My wife and I have the same problem since the update. It looks like the GPS lag to update the position. Rebooting seems to solve the problem temporarily... But I don't want to have to reboot every other day.

Same problem here. Has anyone gotten a solution or has it started working again by itself?

Has anyone tried refreshing the a-gps data? Might help, I use gps test plus.
https://play.google.com/store/apps/details?id=com.chartcross.gpstest

Same issue here. Rebooting brings things back but that's not a solution. I'm on 9.0.0.178 with the CLT-L04 in Toronto.

going to check this soon.

No problem with GPS on my Pro.
9.0.0.163
OTG Update with full wipe

I have the same issue but only with google maps. Waze and other GPS functions work fine. I usually reboot and it works for a few hours.

Huawei acknowledged a problem
It's my first time posting here, as it's the first major problem I've had with my P20 Pro over the past year. I started experiencing GPS problems after the last software update. Like others reported, they'd go away after reboot but not for long. I tried a factory reset, which doesn't seem to have helped either.
I contacted Huawei support in Canada via their website. I got a response today which first suggested I try wiping the cache partition (restart my phone, hold down the volume-up button, then you get to an EMUI maintenance screen with this option - this also didn't help any more than restarting). But it also acknowledged that there is a known issue that they are working on fixing in the next update. I quote:
" In case the issue persists, we would like to inform you that this is related to the new software update, however, Huawei is currently working to solve it. This issue will be optimized in the new version, this one is expected to be released in March. You will automatically receive this update that will solve this issue your phone is facing."
I thought you all might like to know this. I'm keeping my fingers crossed!

I just updated to the 9.0.0.236 version available through FirmwareFinder and rooted as well. GPS is working normally again!

There's an issue with the latest pie ( android 9.0) and the P20 Pro that bugs the gps out, you have to restart your phone every times you want to use your gps. There should be a patch around March 21st 2019. In the meantime if you want, you can always factory reset, which would solve the issue, and wait before reinstalling the latest firware

Any news about that issue ? I have the model CLT-L29 C636E2R1P12 with Android 9.0.0.234 and it's not working the gps....

I have the 213 update for my L04 and it now works great! If you have the Canadian model, check for the update! It didn't work with the 178, now it does!

Im also experiencing gps problem CLT-L29(C636) 9.0.0.234

i thought that i had the same issue but finally i found out that the problem was the new phone-case i put which has metal parts and blocks the gps signal. After remove the case gps works as it should.

Mine doing same. Always searching for gps. How did u fix it?

Same here. At first I thought it's EMUI, but the GPS was still broken after flashing lineage... Any chance that the gps will work again if I roll back to EMUI 8.1?
