Update

Unified with Redmi 5A from now on!

Added full RGB LED (It's slow while selecting the colors, but I'll improve the HAL soon)

Added new poweroff charging animations (Yay, it even shows percentage)

Fixed calls over bluetooth

Updated screen off gestures ( Added some new goodies)

Updated Camera to the latest CAF tag

Updated Kernel to the latest CAF tag

Upstreamed LineageOS sources

You can find the remaining bugs in the OP.Due to my broken Redmi 4A I can't deliver that many and bigger updates. I should receive the replacement parts in about a month. (I didn't find any faster delivery at a reasonable price..)Grab the update here BTW: You will need a TWRP with custom vendor support like this one.
