NOTE 9 Im using my fingerprints to unlock my screen. But the issue is when i lock the screen, and come back to use the phone at the same time i swipe on the screen it gets unlock (strange) i did not put my fingerprints then how its unlocking without fingerprints.
later on i did not use the phone for a while and swiped my finger on the screen, it didnt work then i unlocked it with my fingerprints. but the same above scenario repeats.
