camera's show black screen on iPhone 4
I bought this iPhone 4 on eBay ad read works perfectly so I gave it to my son. He turned it on straight talk and after 3 days came to me saying the cameras front and back don't work at all. The camera function comes on but the screen is black for both cameras,does anyone know where to start my fix. Thought it might be both cameras bad but not sure,someone help me please.
Es esta una buena pregunta?
