Default The touch screen has gone crazy

Has anyone had this problem? Is there a fix?.

The past few days the phone was acting up..As if a ghost was thumbing thru the phone????!!!!
It's like an invisible person is playing with the functions and touch screen.

The problem appears on sunlight. It solves momentarily when I turn off and on. After a while, appears again.

Never happens at home or wing shadow.

Sorry my english.
