The orientation is certainly not working yet as it uses some of MM samsung libraries. (In fact, Wi-Fi/BT is too, have to use patch from Doogee X5Pro)
Haven't tried Proximity/Accelerometer yet.

E: pretty sure I am going to fix main stuffs first like audio, media, MTP, Lock Screen Security (because I removed keystore lib to boot this phone, can use porridge's too) and the hardest which is RIL/Telephony as this phone is the first of a kind.
