Is it normal for my iTouch screen to go white?

Why does my itouch send me back to my home screen when i go to apps?

• this barely started happening a day ago, when i go to an app my screen will turn black and go back to home screen. how do i fix this?

• Answer:

  I'm pretty sure that means the app is crashing as soon as you open it. Whenever I had that problem, I would hard reset my phone to fix it. To hard reset, hold the Power and Home buttons simultaneously for about ten seconds. When the screen goes blank and shows an Apple logo, you'll have done it correctly. Wait for it to finish rebooting, and try again. If that doesn't work, confirm that your phone is able to run the apps in question. I know that some apps require a certain iPhone model to run properly, so make sure your phone is capable of using the apps in question. If the problem persists, try posting the problem on Apple's official forum, or speak with an Apple employee over the phone or at an Apple store or something. Good luck! :)
