Thanks for reporting all your issues.
- Those having random Reboots, just wipe your cache and dalvik from TWRP.
- For charging issues, it could be due to surrounding temperatures but I'm still digging in the kernel what it could be.
- The mobile data dropping issue should be fixed in the next build.
- Face Unlock unlocking on swiping on the lock screen is a source side disability, I have informed core team to look into it.
Cheers,
Lakshay.
