How can I stop my Samsung S2 8 inch tablet from locking up?

[AC Question]

samsung S2 8 inch tablets locking up

Had a total failure on finger print scanner then locked out restarted no change.
Tablet replaced.
After 3 days failed and locked up or died on password only.
Off too factory 4000 K.s trip.
Is it smart to have a home button also part of the security system ?

Welcome to Android Central! If the fingerprint scanner was failing, was it not recognizing your backup password either?
