Known Issues
Current limit reached with speaker
If the volume is set to 100% and you play a loud audio, there is a current peak where it reaches its limit and the Fairphone will crash. You then need to simply boot, and everything will work again. (This is replicable when playing the yolla remix ringtone at 100% volume)
Earpiece microphone bug
When you’re on a phone call. The earpiece microphone does not work. To fix this, toggle speaker mode on and off. Afterwards it works like normal. (THIS IS NEEDED FOR EVERY PHONE CALL)
Auto-Brightness Glitching
After first installing this build, the brightness might go up and down continuously. This is a bug with auto brightness. We will fix this bug in the future, but it is still currently present. As such, you’ll have to keep auto brightness off.
