I am firmiliar with most technology, which is why I bought the iPhone 4. I have not had any problem until now. My LED light is randomly coming on. I have an app for a 'flashlight' and I thought I had accidently turned it on. But I hadn't. The light will come on usually when I get a text or phone call, maybe hardware is loose inside the phone and when it vibrates it turns the light on. If I give it a light bump, the light will turn off. Anyone else having this problem and what was your solution. Thanks.
