[3.x.x] Automatic display brightness adjustment stuck

@AkiBerlin Your log has failures to start proximity sensor and accelerometer -> likely that all sensors are failing (except fingerprint sensor which is not handled via the same route as "regular" sensors). Which then explains things like ...

If the last value reported by proximity sensor is "covered" -> fingerprint wakeup is not allowed to turn display on. (Power key turns display on even when p-sensor is covered and thus still works.)

If the last value light sensor reported was "low light" -> automatic brightness tuning leaves display too dark.

Accelorometer is used for orientation -> switches between landscape and portrait probably do not work, and so on with other features that rely on sensors.

@spiiroin: thank you - accordingly my problems go along with the other problems reported here in TJC (which in a way is good with respect to fixing the problems).

I wonder what causes the sensors stopping to work.

BTW: I do not have this problem with the XA2, only with the Xperia 10 (both on 3.3.0.16)

@spirion: very good hint, thank you! Indeed I have this problem after for example using the Zoom App with Android support on the Xperia 10. Annoyingly, the proximity sensor is active when using Zoom so that touching UI elements close to the proximity sensor is rendered impossible. Even after quitting the Zoom app, the proximity sensor stays active. Stoping Android support also stopps the proximity sensor form being active.

The problem with the very dark screen (it is not black!) cannot be cured by stopping Android support, however. I know it co-occurs with the fingerprint sensor wake-up fault, but it seems not to be related to the proximity sensor because touching the finger print senor triggers a signal (I feel vibration) but does not result in a lit up screen.

I will check the sensors with the CSD tool next time I encounter one of these problems (btw: they are rare)

CSD tool identified correctly that the issue is caused by light sensor which is not working when this happens.

Could it be also hw-related due to failing compass test?

Anyway, I suspect some Android app, I have to figure out which one is causing it. Weird thing is that I wanted to lower the risk of incompatibility and issues and I install apps only with Aurora store.

Although, can I check system logs for some pattern? Any ideas?

Regarding the Xperias 10 sensor rotating problem, this also occurrs to me from time to time

Still just observation of the problem, but it seems to be related to Android apps when handling display dimming.

If I watch a video, pause it and keep it like that, application, which will try to keep the display on, is more likely to cause that issue.

Please let me know where to look for logs and I will try to gather it.

And yes, sensors get stuck on some unsupported value which effectively disables them.
