GPS Not Working on Redmi Note 9S

[Phiibuntu]

I was preventing app suspension with tweak tool yet
1 hour in car I was thinking it was enough. But I take the point and I'll try 30mn in a field to be sure that gps fix can work

Last try this morning GPS doesn't synchronize 30 mn outside nothing.

unfortunatly I think I'll have to go back to another OS, it's sad I think UT have a lot of qualities

@phiibuntu Maybe try to reinstall UT with installer to fix this (no wipe), or try OTA-21 upgrade to see if it solves the issue...
GPS should work.

I can't reinstall without wipe there's too much issue on Xaomi redmi note 9S.
(error 1 error 126 etc. bad repertory, bad rights I think).

Only way ton install UT is :
Install MUI officiale firmware (Android 10 not 11) so totally wipe UT
then use ut installer: and it works nice

@phiibuntu Hi all, I got this working today, it turned out to be quite simple. Now, I am unsure of all the caveats, but this is what I did and it worked after not behaving for a long time:

1. Turn location on

2. Go to system settings > security & privacy > locking amd unlocking > lock when idle: Never

3. Get the SensorStatus app

4. Set it to never suspend with the UT Tweak tool app

5. Reboot

6. Open sensosstatus app, go to GPS

7. Leave next to the window for some time (it wasnt excessively long, but i also wasnt paying attention). I think the point is to stay still.

8. After some time it got a lock and started reporting my location! Unav and whatever else works now!

So are all these steps necessary? Idunno. But its what i did and it worked! Hope this helps!

Cheers

@phiibuntu
I marked it as solved.
I doubt OP will come back anytime soon

@j-mackay93 You don't need the Sensor Status app for gps to work, but it may be handy for diagnosis of problems.

Instead of setting the lock screen to never, which will drain the battery quickly, I suggest you prevent Unav suspension from UT Tweak Tool so that the screen locks when Unav is not in use. The same applies to OSM Scout Server if you want to use off line maps.
