Hey, thanks for the patch.

Color devices need to specify that too, so won't loose color when being treated as EinkDevices.

See https://github.com/koreader/android-luajit-launcher/blob/master/app/src/main/java/org/koreader/launcher/device/DeviceInfo.kt#L686

Can be merged. Unfortunately no official build support for lights at the moment :(
