If your WiFi connection is unstable, consider disabling Bluetooth.

$ sudo rfkill block bluetooth

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.

Charging

rt5033-charger driver is not available, so the charging is not controlled and there is no charging status reporting. There is also a forgotten patch[1], Jakko is looking into this.

USB OTG

Another rt5033-charger driver issue. It's currently unable to power up a usb device in mainline. Try a hub with external power supply.

Ambient Light/Proximity Sensor

The driver for cm36652 ambient light/proximity sensor is not available.
