My tablet got stuck  in it's lock screen and showing incorrect password and telling wait for 30 seconds. 

At last I had to reset it and this is the 2nd time it has happened on my galaxy tab a 10.1

Hey,

If you cant remember the password, then software can be reloaded by software update at the service center.

I knew the pattern was correct i could do it while closing my eyes. it just showed that it's incorrect and showed try after 30 seconds although it was the first time. this wasn't the first time it happened.
