    If you set up fingerprint recognition on the Samsung Galaxy S10 Android phone, it has been found that anyone’s finger can unlock it.

    The Galaxy S10 has an in-screen fingerprint reader that works using ultrasonics to scan your finger and the problem appears to be that if you put a screen protector on the phone, it messes with the fingerprint recognition. Basically it thinks everyone’s finger is a match.

    The problem does not seem to affect the phone without a screen protector and it may be only certain screen protectors that cause problems.

    If you have set up fingerprint recognition and have a screen protector, test it. If it recognises your left thumb, try your right thumb, or get a friend to try it. Remove the screen protector if any finger unlocks the phone.

    A software fix will hopefully come from Samsung to fix this, but in the meantime, beware of screen protectors.
