GPS stopped working - ZTE Axon 7 Questions & Answers

Hi guys,
I've got an A2017G running A2017UV2.1.0B12 (So European running American firmware).
It's been working great for years, but recently the GPS antenna stopped fixing satellites. Previously the GPS was a bit slow, but I'm confident it was working to some extent. Now it's unusable.
It does see lots lots of satellites when I run the GPS status app, but does not lock to any even after resetting the AGPS data, recalibrating the gyro and accelerometer... I've tried installigh stock A2019G firmware and the problem was not resolved. I have made some hardware changes over time (battery and vibration motor), but I'm not sure the problem started after one of them. Yesterday I opened the phone and tried to identify the GPS antenna contacts, but wasn't sure which ones I had to look at. They all seemed to make good contact and I even tried forcing a contact with alluminium foil. Nothing. GPS Status reports the GPS sensor is working, not sure if that's reliable data. Does anyone know where the GPS antenna is?
I'm wondering if this is a hardware issue or maybe something went wrong with the firmware radios (not sure I fully replaced everything replaceable when I installed European software).
Any ideas? Thanks!

Anyone had GPS fix problems?

Has anyone had problems with GPS fix at all? I was using my Z1 in the car today with TomTom Go and I was getting problems with it losing GPS positioning. The app would just stop updating location. At first I put it down to it being just another bug in the app - it seems pretty buggy. But after giving up on TomTom and using Google Maps that app also reported loss of GPS fix, even though it had a good clear view of the sky. So I suspected a hardware fault. But at a traffic light I managed to pull up the app GPS Test and it showed good reception with 25 satellites in view and 13 in use - yet no fix. Which suggests to me there is some error in the GPS software handling. This is the one problem I have had with the phone so far, anyone else?
No issues with my GPS, Sigyc works like a charm!!!

No problem with the GPS with mine.
Try the app "GPS Fix" it always fixed GPS issues with my N4
Had this problem already 2 times, rebooted the device, and error is gone, it's not very stable in terms of software, my Honor 6 was much more stable in terms of software, only the ui sucked bigtime
I seem to have serious GPS fix problems. None of my navigation apps works correctly probably because GPS system loses fix for 10 or more seconds at a time for unknown reasons.
I can have pretty good satellite situation with great 3D Fix:

And a moment later with satellite situation almost the same there's no fix for several seconds:

I need to test it more, but I'm quite unhappy at this moment. Any ideas how to fix that?
No problems.
GPS used quite often and works OK.
Works perfectly fine with Google maps
Cleard GPS cache (with some GPS Fix app), rebooted and GPS works as intended. Problem solved.
No problems with gps

I have got similar problem. Waze or any GPS nav is loosing GPS signal. I have monitored via GPS app satellites nad signal is generally very weak. Lasting long time to connect and during navigation is GPS for application dropping. While signal in Waze is lost I was checking with GPS app and 3Dfix was lost.
I'm really pissed and sending phone back for repair...
Do you have same experience somebody else...?
- PS: I have rooted phone with king root but can't tell if GPS worked well before or not, because rooted in second minute after I have unboxed
I noticed a very bad GPS reception in larger cities and especially in my car using Google Maps. Sometimes it was losing the fix altogether and often it was way off on the position.
Edit: Tried the Fast Fix APP from Fdroid and a GPS Fix APP that suppostly clears the GPS cache. Will See how this works out.
Works perfectly fine with Google maps, here,
I have a problem with GPS to. Satellites-Signal is very good. Fix is ok. When using a Nav-app like Sygic, TomTom or Navigon after 2 or 3 minutes the signal is gone. Here or Google maps working fine. Any idea?
I've got the same problem. maybe every 15-20 minutes google maps tells me "GPS Signal lost"... And then it seems to stay lost until I close the app and open it again. Very annoying, especially when you're in a city and got a lot of turns coming up -.-
Same problem for me, I dowload lots of GPS apps to try to fix it, but nothing works. Most of the time it works outside cities.
I love my Zuk Z1, but it's very annoying because I use Waze for my work everyday. If nothing is done I'll probably change it.
For information I'm in France. Can it be a location problem ?
I tried to fix the problem with many "GPS fix" app but found that simple reboot solves the issue temporarily. I don't know for how long exactly because I use GPS every couple of days. There's definitely an issue here with the GPS.
As far as I know this hasn't solution, so I reclaimed my Z1 under warranty. I must say I'm quite disappointed.
I do have the same problem with ZUI new version. I have seen the bbs.zuk forms site many peoples has reported this issue. I was using CM12 and it was working fine. But definitely it's much better than CM 12
Works perfectly fine with Google maps here too.
Only small problems while on the train, but I think that's normal.

compass wont work with any ROM

Hi, I have a problem with the compass on my UMI zero. When I use google maps or any compass app the direction pointed by the arrow is always the same whatever direction i rotate my smartphone at. Only sometimes it points in the right direction but slowly rotating to the same wrong one. What's going on? I tried to install different ROM but the problem was never solved, and at the beginning it was working, i cannot say flawlessly but at least acceptably.
Compass problem
i was facing the same issues as you are with UMI Zero's compass especially on its stock firmware (update 3.10), but i went ahead and got the rom from this thread
http://forum.xda-developers.com/and...-miumizero-miuiv6-umi-zero-t3050090?nocache=1
and installed the firmware available on it.
i also made sure that all GPS settings were on before using the compass because without it (try using it with the data on for the first few trys), it kept telling me to wave the phone in the shape of an 8 to recalibrate it. it works now much better than before but it is still not completely accurate. i think the problem is within the hardware rather than the software.

GPS Problems

Hi there my GPS was very quick under Kitkat with immediate fix and perfect compass. Under Stock Lollipop it still worked well enough. Since I use [5.0.2][D802] Google Edition 1.5 my compass doesn't work anymore and GPS doesn't fix at all or takes 10 minutes shows wrong location and looses signal again
I don't know whether the problem is the ROM or that my phone fell down hundreds of times.
Anyway I already tried the apps fasterGPS, gpsStatus and TopNTP without success and did the cardboard mod hardware wise.
Please help I want to play Pokemon Go

A clue to fixing GPS

Hi all,
I recently upgraded from 4.4.2 stock rom to 6.0.1 stock rom and everything worked fine except the GPS. I tried a few different fixes like changing the gps.conf, and a few different apps and could see there was some signal but it could never seem to get a lock. Sometimes it seemed to get a lock for a split second then drop it again.
I ended up going back to my 4.4.2 and GPS works fine again. So the simple conclusion is this is firmware based. I'm no expert but would be willing to help if someone wants to investigate this further. There has to be some GPS related files from the KK firmware that can be exported to MM to make it work

GPS has always been kinda weak and slow due to the module itself. Did you experience the auto brightness bug as well?

Auto-brightness was working fine for me. Just the GPS issue noted.

GPS Problem on custom ROM [Havoc OS]

Bout 3 weeks ago i flashed Havoc on my phone and everything went great, rooted with magisk just perfect.
I am now out of quarantine and realised location WONT work even though it's open.
Any help?
Anyone similar issues?
I didnt have problems with stock rom so it's not the antenna itself!
ROM: https://forum.xda-developers.com/lg-g6/development/rom-havocos-v2-1-t3893668
Gapps: "SUPER" package from https://opengapps.org/
I also have Magisk Installed. (rooted)
Bump. I still have this problem

Download app such as 'GPS Test' from the app store and check if gives you any numbers, whether it is detecting and connecting to satellites etc. Also, go into location settings and make sure either 'High accuracy' or 'Device sensors only' mode is selected. In software based issues such as custom rom sometimes battery saving (networks only) setting on its own doesn't work properly. If you still can't figure this out, best thing to do will be to install stock rom once again and for sure rule out that phone has not developed any hardware issues since you installed the custom rom. I had similar issue with a G6 once and I went through many many troubleshooting steps to fix it and in the end I left it alone but was pretty sure it was hardware failure because the GPS couldn't latch onto more than 2-3 satellites at a time. I remembered later that I had dropped the phone which probably messed up or loosened the GPS antennae connections.
