I have a galaxy tab a. I have tried to unlock it after it being fully charged but every single time it says wrong password even though it is the correct one and I haven't changed it. someone please help i have a lot of important data on there and don't want to lose it all
restart it using factory settings - unfortunately you'll lose all the data you've input BUT use what has happened as a wakeup call - only use the security settings if there is a danger of someone using your device whilst its switched on without you being there - but ask yourself would you leave your bank card in the ATM and walk away? That is the answer
