I bought Samsung Galaxy A7 2017 last month, I added three fingers to the fingerprint scanner - two thumbs and the right index finger, but today I discovered that it works also on the left index finger (I didnt add it). Does this mean that everyone can unlock my phone? I thought it would be safer ... I looked closely, both fingers have differences in the fingerprints, so I doubt that the phone recognized it as the same finger
not at all i my self have been using this phone personally and its fingerprint works perfect and faster i have compared the speed with 6s plus and ipad 2017 but a7 got the fastest fingerprint among those so u dont need worry regarding security reason
