A while ago the FP3 in question was accidentally let to lie in the rain. After thoroughly drying it, at first it seemed as if everything was still functional but now there are (at least) two things that don’t work anymore.
First problem is that the phone doesn’t turn the screen anymore, even if automatic turning is enabled, so I assume the position(?) sensor is broken.
The second problem is the sensor for automatic screen brightness management seems to be broken too, since even if enabled, the phone won’t automatically adjust brightness according to the environmental lighting anymore.
If someone could please advise me which modules would need to be replaced, to fix these problems I’d be thankful.
Thanks for the quick reply @amoun
So the brightness problems probably are caused by the software update. But you’re saying the sensor that is responsible for screen turning is located in the core module and so cannot be replaced by myself?
That’s a pity.
Ok sorry, then I misread your reply. The phone is working just fine all in all, only the two problems that I’ve described (automatic brightness and screen turning) are occuring.
When you’re saying " the sensor may not be the issue" what possible other issue are you thinking of?
Dial *#*#66#*#* Then Service tests > Test Single > Ambient Light Sensor in this case and then see if that corresponds to the issue linked to above.
If the Ambient light sensor doesn’t work at all then sure you have a different although related problem… By the way note the sensor is badly calibrated and reads zero when there is adequate light for reading books etc, so test in a bright situation.
@amoun I’ve now used the Service menu to test the sensors and the Ambient Light Sensor seems to be working just fine, so that problem must be connected to the software updated you mentioned.
But when I test the Gyro sensor, the only output I get is:
It's fail! SensorType = 4
So I fear it might actually be broken. Is there any chance to repair that myself or is the core module repair mentioned here my only hope?
When drying I took it apart as far as I could as I lack the tools to open it up due to the screws, maybe I should get a fitting toolset. The phone was not immersed in water, but “just” lay in the rain for a while before it was found.
I now also tested other sensors and the pattern seems to be that Compass, Accelerometer and Gyro are all broken/not responding, but the rest of the sensors seem fine.
Edit: Stupid me, after a reboot they are suddenly working again. But I’ve definitely already rebooted several times since the water damage, so this might be an on/off situation if the sensors are working? Or could this also be a software problem? If yes, is there a way to log output if it happens again and send that to Fairphone?
