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.

I opened the phone. Now i need to know where is the GPS antenna, anybody know?
In sony it says its near the headphones plug. No more details.
Thanks

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.

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.

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?

OnePlus 3T GPS Issue with Mobile Data and Location both "On"

My OnePlus 3T is running Build Number ONEPLUS A3000_28_180915. Android Version 8.0.0.
The issue is that my phone's GPS is working when Location is on and works with or without WiFi when I have Waze open.
But, once I use my Mobile Data + Location = my GPS now becomes intermittent especially in Waze. It keeps on connecting and disconnecting for some reason. I also have tried having my Location at High Accuracy and Device Only and the problem still exists.
I have already tried using GPS Status and Toolbox, Cleared my Cache, re-installed my OS and I still have the same result. Up to now, I have not yet been able to resolve this. I hope someone can help me with this issue.
Thank you.

I (along with a number of others) had a problem with GPS on a much older stock OOS build, around October 2017. This was a problem with the ROM having outdated aGPS data.
Not sure if that is similar to your issue. I didn't have any problems after that one build. There is a newer build than the one you are on (181206). So you might try to update, and see if that helps.

Thanks for this! I'll try updating to that this weekend if I have the time and I'll give an update here.
I honestly don't want to give up on this phone just yet even if it's already a number of generations late already.

I tried flashing the latest ROM from OnePlus for my Device and I even did a Restore Factory Settings and it still does not work. Would you have any other idea what could possibly be causing this? Thank you.

GPS not working after March update

Hi guys,
So gps is not working well. Waze and google maps can't get a close on my location when i'm trying to navigate. I've had this issue with the first version of the pie update but that was fixable with disabling some google service in the gps settings. Now that does not help. Any of you have this issue? Can anything be done to resolve this?
Cheers

Hi,
I'm facing the same problem too. This is getting really frustrating. One update fixes the problem and the next one messes it up again. I'm really tired of this...

Anyone got problem with GPS for a tencent version with global rom?

My rog phone 2 tencent version with a global rom and fingerprint. Apparently the GPS is not working at all. Google maps and other apps not detecting any location at all.
Anyone got the same problem or solution?
thanks in advance

Works fine for me, not sure what would cause that. Do you have "Use location" on in privacy settings?

Yep. Checked all options about gps. Actually after waiting so long, the gps worked but really slow to lock the location.

No problems here and it locks on quickly - even indoors. Around 50 satellites in view and 20 in use according to GPS Test.

Thx for info pal, hope it will get better after another firmware update here ?

Have the same problem
I noticed also a problem with GPS locking, the problem persist also with the Android 10 beta rom i uodated like 2 weeks ago. Interresting fact is, i only get this when using Waze, either on the phone or through Android Auto, with Google Maps for example i working flawlessly. The only fix i got is installing an app called GPS Lock, which apparently forces the phone to lock on the satellites, but it's quite a battery consumer though. Hope also for a fix in future updates.

I happen to encounter this a lot especially when I travel. Download and install the app ''GPS Status & Toolbox" then turn off Wi-Fi. Once your Wi-Fi is turned off, open the app and that should fix it.

I had the same issue. Can see gps satellite but can't lock onto them. It was my metal bumper casing. Wasted my whole day testing things out.

Anyone figured out a solution to this ?

I'm having this issue as well. I'm using the global version btw. Hope someone posts a solution for this.
