i put my phone in my jean pocket the other day and when i pulled it out there was white lines across my screen so i smacked it and it fixed and its been doing it alot and now it wont go back and i cant enter in my password ( its a pattern password ) how much do you think it will cost to fix it?

Zerrik Mitchell  could just be a loose connection on the display connector or a bad display. The display assembly is around USD $30 so if you do it yourself that is what you would be looking at. If you need to get it repaired then it will depend on where you are located etc.
