I got my iPhone 4S a week ago since I got it, it seems I can't open the photo app.
I can't see the pictures I have taken. Whenever I try to open the photo app, a white screen appears for two seconds then closes by itself.
The videos I record don't seem to appear on the video app as well. The video app opens, but it shows that it is empty.
I tried to reset the device but it didn't help.
How can I fix this error?
