Hello,
So, as the title tells, i've got some GPS issues since i'm using custom rom (both TW and AOSP ).
Nearly each time, it takes up to 15 Minutes before the first lock is made. So the usage of Google maps or any "speed control" apps is quite impossible.
I tried GPS status app and let it download new AGPS data. But even when I am outside it finds only 1/2 satellites without fix.
I think i'm gonna reverse to a Stock ROM tonight in order to test if it's really rooting problem.
Anybody has an other idea ?
Thanks,
It's closed now .
It was an hardware problem.
Hi,
I've done a fair amount of searching on here and google regarding the gps issues with this phone. Tightening the screws definitely helps with the lock time, but I am still having issues with the device dropping gps lock when the display is off.
I have an S3 Mini running stock Android 4.1.2 and mainly use Viewranger for mapping and the GPS status app. Both apps work fine while the display is on, but when it goes off, gps lock is lost after an indeterminate amount of time. Setting GPS Status to 'Use gps when screen is dimmed' makes no difference.
I use both of the above GPS apps on a HTC Wildfire and a Galaxy Tab 8.9 and neither drop GPS lock when the screen is dimmed, so it is definitely an issue the S3 mini.
Here's hoping for a fix on this otherwise great device!
TIA

Maybe I should rephrase the question
Is anyone here *not* having a problem with GPS lock when the display sleeps?

I hav the same problem which means I'm unabble to use running apps.... Have you found a solution?
No fix yet unfortunately, and it's looking increasingly like there never will be one.
I've been taking a GT8.9 in my backpack for GPS on walking trips. I'll also keep my old wildfire in case I need a pocket-sized GPS device that actually works!

Hi, i've just purchased the S3 mini phone and I have the same problem. Previously I had a Wildfire S one and I've never had any problem, even taking into account I use GPS to track my trip when I sail on the sea. I'll try to summarize some clues I've found:
- Samnsung Galaxy S3 mini with Android 4.1.2
- I usually use "Marine" app, from Navionics join "GPS Status"
- The problem only appears with "track" option, after stand-by, but after an indeterminated amount of time.
- Once we check the GPS is not working, I can see on GPS Status the satellites but no one providing position (i.e. value of 0/12 on pos/sat field). Finally I need to restart the app, GPS Status and the GPS to get the connection again.
- In other forums I've ridden about not to switch off the screen to avoid Android turn off the GPS because of energy safe mode. With tracking function should not be necessary do it.
I hope anyone can give us some light.

I have the same problem and think I have the solution (I am still testing, but sofar so god).
Use Keep My GPS Alive (testing) or GPS Keeper Lite / Keep Alive (still to try). Look for them in google play.

Thanks for the suggestion but I tried both of those apps and neither prevented the gps dropping lock when the screen was off. In fact, my gps/map application would stop tracking my location when the screen was on and either of the above were running in the background, so they actually made the situation worse!

Have the same problem. Often 0/12 with "strong" signal. But no FIX. And it happens short time after 11/12 (or so).
This happens with various ROMs (all based on Stock)

Hello everyone,
I've had my Xperia Z for around a year now and I have used it consistently with cyanogenmod with no issues regarding GPS. The only time my GPS has failed to work properly, I flashed the stock ROM and then the latest cyanogen build to get it working again.
However this time my GPS will not function whatsoever, I have flashed numerous stock and cyanogen builds to no affect. I have also tried every GPS app I can think of to tweak my GPS settings and try to see if any satellites will show up, however none of these approaches have worked. I have come to the conclusion that the GPS hardware must be faulty. Is there anything else I can do, or is it broke for good?]
Many thanks.

Flash the stock rom, go to service menu - service tests - gps. If it doesn't work relock your bootloader. I hope you backed up your TA Partition, because it would make it easier to sent it to repair...
Hello, recently my phone's screen got broken and i replaced it a few weeks ago. However I noticed that the GPS was not working so well. I was searching and downloaded the app GPS Status and did the reset the gps data and stuff.. The problem was not solved, also I noticed thad where it says "Acceleration [g]" if i let the phone on the table it shows a value of 0.13 when it should be 0. Is that a hardware or software problem? I have already done a factory reset, install a custom rom, get back to stock and the problem is still here.
I would be really greatfull if someone could lend me a hand here, I use a lot the gps!
I've honestly never been able to get the GPS to work properly on my phone, and no clue why. Thankfully I have an old cell that the GPS works on without needing any service
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)
Baseband: 8974-AAAAANAZQ-00005-05
Kernel: 3.4.0-g0961cdf Build [email protected] #1 Tue Aug 19 19:48:36 2014
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.
