After updating to Android 12, the rightness of the display of my #fp4 randomly decreases, but eventually temporarily reverts to correct brightness, repetitively. The period of time during which its brightness is less than it should be is always greater than the period of time during which its bright…

I found this to be easily reproducible without any sun involved: disable automatic brightness set maximum brightness manually start a game like Mighty Doom or MTG Arena and wait about 2 minutes (the game would heat up the phone enough to show the dimming behaviour) So I’d say no need to wait for …

It happened to me again today. But maybe I found a workaround: when the screen went dim, I covered the front-facing camera for 5 seconds: the screen went a bit brighter (weirdly enough, it should go dimmer when it detects darkness) and when I removed my thumb, it went back to full brightness. I’ll …

[image] O.o: covered the front-facing camera for 5 seconds: the screen went a bit brighter (weirdly enough, it should go dimmer when it detects darkness) Just to avoid confusion, the camera does not contain such sensor still its close and you might have well triggered it. Thats the current si…

[image] yvmuell: Just to avoid confusion, the camera does not contain such sensor still its close and you might have well triggered it. Yes, usually the proximity or ambient light detector sensor isn’t far. That’s what I meant to hit when I covered that area with my thumb. I didn’t describe i…

[image] O.o: I’ll try to confirm whether this trick works next time it happens. It doesn’t. I guess the first time was a fluke.

deleted for false information - Edit: I falsely assumed I installed a new fairphone patches. Turns out, it was only CalyxOS patches. So actually nothing new on the Fairphone side of things.

Wait, are you sure that you have the July update? AFAIK, it hasn’t been publicly released yet. The topic you commented on is actually about the June update: [image] Software update: FP4.SP29.B.069.20230510 The Products Edit: already had the version installed and actually d…

you’re right of course. I got an update, but it only was the calyxOS kernel update. I just assumed it included a fairphone update without actually checking. The vendor and firmware versions are still on May 5ths, so nothing has changed there. Well, this means there still is hope … Thanks for pointin…

Now it’s gone really dark and the brightness isn’t returning to normal. The phone is quite cool and I’m in the shade. Rebooting ain’t fixin it. It’s been like this for 2 hours now. Really quite annoying. I’m willing to tolerate this and more because I’ve internalized that there is sadly a price to …

Fixed: I went to the bar’s bathroom, put the phone in a plastic bag and ran cold water on it. It went back to fulll brightness in seconds. If the problem is heat, it sure doesn’t take much. Fix please Fairphone! Pretty please… :slight_smile:

Hi everyone, I’ve made some other tests and debug yesterday. Can confirm that it’s related to the quiet-therm-usr sensor. With an sh script like this: for VARIABLE in $(seq 0 95) do cat /sys/devices/virtual/thermal/thermal_zone$VARIABLE/type cat /sys/devices/virtual/thermal/thermal_zone$VARIA…
