1) Camera doesn't work. Simply keeps crashing and asks to be opened again.
2) Fingerprint registration fails every time, since it asks to find the sensor at the back of the phone??? Athene has it on front.
3) Display size change does mot work for gboard or the navigation keys.
4) Changing font size crashes system UI.
Please find solution to these problems. Also do not suggest clean flash, reboot, internal data wipe. I've tried everything.
No. 3 & 4 works for me on my xt1643
