Need to implement fingerprint support.

Im using letv le 1s... Quite popular online in india.
Searched for roms.. Found aosp.. Cm.. Miui.. Color os.. Etc.. But none of em support fingerprint..
So i thought of porting the sensor...

How can i port fingerprint sensor..

It can be done becouse i saw another device redmi note 3.. Same hardware of le 1s encountered this problem but those guyz made an app for fingerprint.. But i could not find those guyz..

SoC.. MTK6795
3GB Ram
Android 5
