My apps won't open on my iPhone 4s

OK, Let's try a reset. tap and hold the Home button and the Sleep/On/Off button at the same time for approximately 15-20 seconds, until the Apple logo reappears. Release buttons and wait for unit to restart. No content will be affected.

If you are able to use the App Store, download an App, any App. This has been reported as a fix for the issue.

You're very welcome. And thank you for the stars.

Hi. I have tried resetting my iPhone 4S three times and I have also downloaded a free app. Neither of those have fixed the problem. It only seems to be the Just Dance 3/Autodance app that won't stay open but I don't want to lose all my dancing videos on there as they cannot be recreated 😟 Please help me 😟 I've had the 4S from November 2011. I assume that if I delete the app and reinstall it that will delete all of my videos? I can't see another way to get them off the iPhone and on to my laptop.

This worked for me too!

i also have this problem but i cant open my appstore only a few random ones will, any ideas??
