Apps not opening after updating software on iphone 4

[loobs72]

None know what I need to do?

I was a couple of updates behind and now when I press on an app it doesn't open, just goes back to home screen?

Thanks

Did you do a backup before updating the iOS?
If you did I would try reinstalling from a backup.

From my  iPhone 4S 16GB Black
