Chosen Solution
i have i pad 4 WiFi resonantly the back camera is not working it only shows a black screen in this kind of problem what should i do to fix it
First thing first, I would go ahead and check if updates are available for your iOS version. Second, I would perform a full restore of the tablet to make sure the software hasn’t crash or anything. If none of these solutions seem to be working, you are most likely dealing with a hardware problem and opening te iPad will probably part of the deal. Good luck!
