I purchased Mi 5  on 19Oct'16. Handset was working fine, but  6 days back, device didn't recognize finger print . when I checked in settings,I found option of finger print sensor has disappeared. Device is updated with MIUI stable.
I reset the phone with factory reset but still problem has not sort out. I reboot the phone 3-4 times but all in vain.

pls help and tell me what to do to get fingerprint option back. Brand like xiomi these types of bugs has to be fixed
