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)

Thanks

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.

Voice cut during internet calls

I have a problem with my Mate S updated to the latest stock EMUI 4.0.1.
With every app that consents an internet voip call (Skype, Hangout, Whatsapp, Viber) I can listen without any problems my interlocutor but my voice will be cut avery 4/5 seconds for 4/5 seconds each time so that the call is impossible. Only sometime everything works, it seems when the screen is off and then restart to have problems when it is turned on again.
The strange problem is that this happens also with another phone, a Honor 7, so another Huawei phone, and this does not happens at all with Galaxy or other phones.
The problem is present with different internet connections, wifi, interlocutors, so this is not related with the network infrastructure at all.
Could please someone gives me some hints on how to investigate further this problem and kindly tell me if you have faced the same problem?
Many thanks!
UPDATE:
The Huawei official support says that they cannot guarantee the compatibility with Third party Android App so in fact their OS or Hardware have serious bugs and they are not interested in discovering the reason. For them you simply need to avoid using most famous third party app, so do not use your phone like a smartphone.
Please consider buying different company than Huawei if you want to use internet calls

That's strange...I don't have that problems and I'm in the same version, maybe you have a hardware problem.

Thanks for you reply sebastassara. This is the first thing I thought when it happened the first time with my Mate S, in June, but then I bought last week a Honor 7 and I was really sorry to discover that the problem was exactly the same. For this I could not believe that it is and hw issue, or otherwise I would be completely out of luck!
I think more in a OS problem but I am trying to find at least to why it happens or how to solve it, but at least what cause this problem...

[Q] Oreo Update broke GPS

Hello everyone,
Ever since I updated my gn8 to Oreo, my GPS broke. GPS doesn't lock and if it does, it will be gone in a few minutes or so. Anyone else experienced this? Any tips on how to fix GPS? Without doing a hard reset of the phone? I'm not rooted by the way, guys. But if you have a solution that requires root, I might root this phone just to prevent a hard reset.
Thanks!

Factory reset ! A good practice after a major update !
Sent from my Galaxy Note 8 using XDA Labs

Not sure what type OP has with GPS issues...
My N950U1 (SD) has no new issue regarding GPS - it works fine but still no reception/integration of EU Galileo birds..

Im have gps issue
Me too...whn 711 update to oreo..gps cant lock stelite

Try a factory reset maybe? GPS working fine for me on Oreo (N950FD).

Do have a look at my other post on GMaps and GPS. I am sure Oreo broke something with GMaps navigation and GPS. I have tested this extensively and I confirm it is an issue.

I GOT my phone used and yesterday noticed that GPS Doesn't get any signal
i don't know if this is hardware or software issue
any solution for this issue
it's really annoying

You can try a gps fix app from the play store, but if no luck then try a factory reset or flashing stock firmware. If still not working at that point might be a hardware issue. In that case would contact seller, or worst case samsung for warranty repair if possible.

Find Device Closed Unexpectedly

I got an OTA and updated to global miui 11 v11.0.2 and faced this problem.
When I use my Mi 9 about 1~2 days it suddenly reboot and get "Find Device Closed Unexpectedly" message
Does anyone know how to solve it?

same problem, MIUI Global 11.0.5.0 (QFAEUXM)

Same issue after Miui 11 (11.0.2.0 and 11.0.3.0). "nice" to see that its also happening on EU Roms, was already thinking about to switch back from global but looks like its not worth it.
I did a clean installation 2 days ago to see if it fixes the issue, but after 1 1/2 days it's back.
Edit.
Uninstalled now the xiamo device search via ADB. Lets see if this brings any improvement.
Edit2.
Not the best idea, device ends up in bootloop after reboot.

i used to get "find device closed unexpectedly" about once a day and it always happened at the same hour. i tried everything including ADB, hidden MIUI settings etc. to get rid of bloatware etc. - didn't work. then i changed to a USB router instead of USB tethering and there is no more issue

I did a clean hard reset and did not restore any data or Google backup on my device.
Everything was working fine for a week but then I set alarm clock and added a mi notice widget on Homescreen. As I woke up the next morning I had the error message again so I removed notice and widget and I forced stop app in app info.
Since then the error is gone again. Fingers crossed!
Does anyone find any same procedure sat its device? So maybe we can surround this problem?

Mine also comes up with an error message, something about not being able to log in to the sim card, I forget the specifics, I can always find it through Google anyway.

Same problem
I tried literally everything to wipe out the error but its still on my phone and freaking me out. Because I went on every foru google tells me, i watched any Youtube Video and tried and tried and tried. My only hope is a system update but who knows if that can fix it.
Good Luck to all of you with fixing this problem

I tried euu and global rom, both have the same problem. Not only in chinese rom. Hence i went back to miui 10. xiaomi is totally clumsy about android 10.

Maybe in Android 11 they will fix it...

I found a solution in another forum:
The unexpected interruptions of mobile and WiFi connections were forced because of AdGuard app.
What causes Adguard to block my internet connection?
I have noticed the same issue with all latest versions Stable or Nightly. This behavior has appeared for several months already. DNS Adguard / DNS google: same thing if AdGuard off 4G is working fine no trouble with wi-fi
forum.adguard.com
It looks like that there is no solution for that until today so I switched to AdAway VPN and the issue since then is gone.

Question Mi 11 echo problem

Recently, I'm facing problems with my Mi 11 device. People who are calling me complaining that they are getting their own voice back through their phones while calling me. I tried updating my device but it didn't help me. I'm hoping for some solution here. Thank you. Cheers.

I faced the same problem too. You can google and there are some solutions that work - disable google voice recognition etc.
Unfortunately, none of the solution work for me and I have sent my phone back to xiaomi for diagnostic. (still waiting for my phone to be back)

Same here, I tried disabling voice recognition as well, but it is still the same.

You can try using a small masking tape to cover the top microphone. - it works for me. But becareful not to block the proximity sensor.
Don't bother to try any other methods like factory reset or any settings. I have tried and it doesnt work. Anyway, this issue is not unique only to Mi 11 but all other phones as well. (other brands included)

Welcome to Xiaomi Mi 11 trouble family, I have echo problem plus wifi problem also out of guarantee and no solution for months.
May be the only solution is:
- Put in the bin and continue your life
