Note Note: Enter lk2nd fastboot mode by pressing only Volume Down + Power (without Home). Pressing Home additionally will bring you to the Samsung Download mode.

Audio

Warning 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.

Proximity Sensor

The driver for cm36672p proximity sensor is not available.
