Iphone 4s touch screen not responding
Hi, i have a problem with my iPhone 4S: just out the blue, the screen stopped working, doesn't respond to the finger touch at all,.
i have try to turn it of, but when i have to slide to confirm the action and slide on the red symbol and since the touch screen doesn't respond, can't turn off the device.
The screen looks totally normal, just not responding, the calls and messages get to the device but i cant get access to the iPhone, so it is like a iVegetable. The iPhone 4S haven't get wet or have dropped, it was in my pocket and when i wanted to use it, the touch screen didn't respond, like I said: just out the blue, help please. Thank you for reading.
Ps.
The phone is 90 days old more or less.
iPhone 4S, iOS 7.0.3
