I updated galaxy a50 but after that when I try to add fingerprint it says "A50 Fingerprint sensor calibration needed." how do i fix?
-Hold power button until the 3 options of power off, restart, and emergency mode appear
-On-screen tap and hold on the power off option until it changes to safe mode
-Select safe mode and the phone will reboot into safe mode
-Once in safe mode try to re-add the fingerprint
this steps but still not working...
As the troubleshooting has not been helpful, it is recommended to have the phone evaluated by a certified technician. Please send a private message with the full model code and IMEI number of the phone and I will be happy to look into your options. http://bit.ly/2XERsky
