Fingerprint scanner bug
After A10 update it was none of this issues until I factory reset my phone. The issues is when I press on the fingerprint scanner:
1. The "blue round light" appear smaller than normal and it wont unlock my phone.
2. The whole screen light up with full brightness and blinding me but it unlock my phone.
Both issues happen 1 time each since this is my 2nd day after factory reset. And while I'm typing this, Chome got freeze. This also first time happen to me. @Anders_ASUS
