Help Email typing problem :(

[chubbs88]

Hey all... just recently it started to happen after I got the new update 4.1.2... I would be typing an email then all of a sudden the cursor moved back up to the first line randomly for no reason and continued from there... if i move the cursor back down and start to type again it just keep going to the first line of the body of the email... anyone know whats going on??

e.g.

Today for some reason my*up* Samsung GS3
started to act

*cursor moving the top line for no reason...


Thanks
