Hello. I am posting for a relative. He has an iPad 2. For the past few weeks, when he launches certain applications, the screen turns black and the application does not launch. For example, I went to Safari, then googlemaps. One time the screen turned blank immediately and safari was existed automatically. Another time the application existed by itself when I tried to type an address. It is as if the application crashed. Any idea what is happening and how to fix the issue? Thanks.
