Rotation and proximity sensors not working?

Apps & Core Settings
1

Hi everyone!
I’m Pol Rojas, from Barcelona on a Fairphone 3+

Recently I updated from 4.1 to 4.2, every worked fine until a couple of days when I noticed that suddenly the proximity sensor were not working, neither the rotation, or automatic brightness.

It is strange, because this morning after rebooting it worked back, and now it failed again.

I was thinking in downgrading to 4.1 to check if it’s a problem from the update, but is there a way to do so without losing apps and data?

Thanks for any thoughts!

This won’t be authorized by the iodéOS recovery, and is very risky. It may, and probably will, break everything.
A system update will be available very soon: you should try it. But it may also be a hardware issue…

Hi ! Thanks for your work on iode, I’m just letting know that I have the same issue on my FP3+. It appeared a few weeks/couple months ago, I’d say after a system update, but can’t say for sure; maybe installing iode 4.7 ?
Anyway I now have the same issue : no proximity sensors, no rotation, no auto brightness.
Phyphox app says there’s no such captors on the phone
Service menu seems to be not working on iode (*#*#66#*#*)
I reboot my phone almost every day but it never works
There seem to have something to try here related to SELinux but it needs root which I haven’t
It’d be weird to be a hardware failure (all those sensors at the same time?)

Would you have some idea of a workaround ?
Thanks in advance !

Self responding to my issue in case it is the same for you Pol and you still have no solution, I changed my top module (the one with the front camera), and all of the sensors are working fine now. I don’t know if the gyroscope is in there too or if it was just blocking it in some way, but I got everything working now

Thanks for your response Caprex. The situation got a few worse a couple of months ago, since the mic stopped working. I changed the bottom module and de mic kept non-functional.
Finally I sent my phone to the FP repair service and they told me that the board has oxidation. The price for a spare is too high so I’m using for some more time until I save enough to buy another FP.
