I've got a extended battery with an ultra thin case and an Iskin on the front. Using the extended battery and a case puts slightly more pressure on the screen than normal but having the skin on the front adds more pressure as well. And now when i type i see that pressure mark on the screen. My question is does that hurt anything? Obviously it's not helping but i didn't know if it would significantly effect the w screen? I'm going to try and dremel the case a lil bit and hopefully that will work. I can take the Iskin off but i don't wanna waste $15. But before someone says it yes i will take it off if i need to.
