Audio

Icon WARNING: The speakers are rather loud on 100% volume and may produce distorted sound that may damage your speakers after long use. Please make sure to use reasonable volumes - your ears and your speaker will thank you!

Screen

Screen works partially. While displaying the UI works fine, adjusting the brightness doesn't work.

Touch keys

See Tm2-touchkey.

Flash LED

Currently WIP. It can be controlled with SG Micro SGM3140 charge pump LED driver[1].

Accelerometer

lis2hh12 accelerometer is not so stable for auto screen rotation, which suggests you to use fixed portrait or landscape mode.

GPS

No idea how to test yet.
