Im have a slight problem next to my iphone Everything works fine on the phone except for a lower inert strip?

The phone powers up and still holds a full charge. No cracks in the screen. but just half of the touch screen is working! please relieve

Answers: Give Apple a call and make an appointment at an Apple store or own them send you a box to send your iPhone surrounded by to get it fixed. If it can't be replaced they'll give you a bright one.
