IOS 8.4.1 terrible update!

Back up your device to iCloud or iTunes and import your Photos to the computer your sync with, and then go to Settings>General>Reset>Erase All Content & Settings. When you set it up, do not restore it from the backup. Download or sync the apps you are having issues with and see if they persist on a "clean" system. If they do not, then that indicates that you had corrupted data on your device, and you will have to rebuild it "manually".

If the issue continues with those apps even when they are running on a clean system, then I would want to ensure that all of those apps were downloaded form the App Store. If any of them were not, that could be the issue.

Also, your device is not jailbroken, correct? You do not have any sort of Anti Virus software running on your device, correct?

Yes, your data would be in the backup, but if you end up determining that you have corrupted data on your device, and decide not to restore to that backup because of that, you would lose data.

However, the "test" I recommended does not prevent you from restoring to the backup you make right before you reset to Factory.

By resetting to Factory and not restoring to the backup the first time around, you are just trying to isolate the issue. You will be able to determine if you have corrupted data, or if you have a hardware issue. If the issue goes away, you have corrupted data. If it remains, you have a hardware issue. But, either conclusion does not prevent you from resetting to Factory again, and then restoring to that backup you made. It just pinpoints where the issue may be.

You did indicate that you have already tried the "hold down the Home and Power buttons at the same time" reset, correct? With only minimal relief?

Have you also double-clicked on your Home button and made sure that all apps have been closed?

Just throwing out a couple of other easier tests than the reset to factory....

I have been having the same problems with my iPhone 5. Unfortunately, I did try to reset my iPhone. After the reset, I could not access my Apple Music library, and the Apple Music menu is as closed off to me as ever (it freezes). All I can do is send feedback to Apple, and hope IOS 9 solves these critical bugs.

Having the same problems here. 8.4.1 makes my iPhone unusable and I don't want to delete all my data.

I have the exact same issue. iPhone 6+ after update onto 8.4.1 freezes when I try to access iCloud settings, appStore settings, when I try to open iBooks. It seems that even appstore doesn't work now. I hope apple will fix it soon...

Did you try Gail's suggestions?

No I did not!

Why not? Why would you live with problems that may be fixable in the hopes that the next version of the iOS may fix problems? If the problems are with an app you have installed or with corrupt data, you may well just transfer the problem to the next version of the software. If there is data corruption on your phone, you also increase the possibility that something may go wrong with the update. Deal with the problem now.

It didn't help. But I followed the suggestions from the following message in the different thread and it helped me. Re: Unable to download apps after 8.4.1 update

Resetting to Factory and restoring from your iCloud backup (as was outlined in my post) does exactly the same thing....
