This is a true story two months ago I logged into my 888 account on my tablet registered to a tournament when I played it all the players names were in Russian my tablet sound bar was moving up and down by itself and some weird poker sounds wtf so I changed my password and problem gone.
I don't believe your story. If hacked account then would be immediately modified the password and email address. And you would never have been able to get into your account.
Either your 888 account was hacked or your tablet was being remotely controlled. Neither makes sense. If your account was hacked, it doesn't mean they can control your tablet. They would log in on their tablet and you would be disconnected. If they hacked your tablet, changing your 888 password would have no effect.
Probably a glitch with your tablet and/or with the software or you made this story up.
I am not making this story up I should have recorded what was going on with the iphone my settings are in English and the players names were in Russian its not a glitch the problem went away after I changed my password.
It was just a glitch in your gadget. This happens with a computer mouse, a tablet mouse and smartphones. I recommend you to clean your gadget from unwanted debris more often with special programs.
