I installed iOS 9 update and from then onwards my applications are not running the way they were used to, something fishy is going on in the back-end I guess. If anybody has any idea about this then please let me know. I need your help
iPhone 4S, iOS 6, null
Hi Shayadri!
I understand your apps are not working correctly after installing iOS 9. I understand how important it is to have your apps working right, and I'm happy to offer some tips. Please try all of the suggestions in this support article, and if you're still having issues with third-party apps, you'll see instructions to contact the app developer for help.
If an app you installed unexpectedly quits, stops responding, or won’t open
Thanks for using Apple Support Communities.
Cheers!
I suggest you check one additional item in addition to Jeff_W.'s suggestions: Your free storage space.
Check Settings > General > Storage & iCloud Usage > Manage Storage (under Storage) and be certain you have absolutely no less than 10% of your device's total storage free.
