iOS 8.4.1 freezing issues

“Use iTunes to restore your iPhone, iPad, or iPod to factory settings - Apple Support”

You you need to setup as a new iPhone after these steps!

DOnt restore from a backup

I have the same but with iPhone 5s. Safari, Apple Music, Mail etc. stops working. Restarting phone helps for awhile but it just keeps happening again. And all this started with the new update.

You could contact Apple Support to run a Diagnostic on the iPhone.

Support could also escalate to the engineering for a proper investigation.

On my iPhone 5s, the update install of iOS 8.4.1 failed. I rebooted all and tried the update again. That failed, and pushed me to a restore. The restore pushed me to a restore to factory state, then initialize as new, reconnect with iCloud, and then a restore from iTunes. None of my manually managed music restored. I will copy that over again. All else seems to be in place. Now will have to test.

Now i see that the OS is listed as 8.4.1. Shows that way both on the iPhone and in iTunes. Is it really? after all that? Any other way I can check what OS is on the iPhone? Everything seems to be working, including Safari. Since all this happened tonight, I'll have to see if it sticks. Looks at least like a bad installer to me, to have to stumble through all that.

I was having the same issues. Tried hard reset, restore with back up and restore as new. Kept happening.

Contacted Apple Support and they are replacing the entire device.

That's what I did, too. That would normally be my conclusion as well, so we'll see what happens.

Similar issues here since 8.4.1. Hopefully Apple will take care of these annoying issues asap.

Got the same problem for a few days with my iphone 6, iOS 8.4.1. And have no idea how to fix it.

Also found the battery on 6+ dropped about 10% in an hour.

Looking at the usage, it reported as the music app (in background) using about 40% of battery.

Killed that and battery usage slowed down.

I having to reboot the phone several times a day to get it to respond now.

iTunes Sync hangs, selecting the music app in settings results in nothing.

So how does one roll back to the previous version?

I'm experiencing the exact same issues with my iPhone 6 on 8.4.1. The Apple store has replaced my phone twice in the last week and I've set both phones up as "new" and haven't synced them with my computer, just to rule out any possibility of corrupt files on my end. It doesn't seem to help. It'll run fine for a few minutes and then the app I'm in (most commonly Apple Music, Safari, or Settings) will just freeze. It's strange, because I can usually exit the app and the rest of the phone appears to be running fine. However, trying to relaunch the frozen app is usually fruitless. Closing the app completely sometimes helps, but usually I have to reboot the phone to use that app again. Then the phone will work for a few minutes until an app freezes up again and the whole process starts over. This is infuriating!!

I have been experiencing the same issue with my phone. First noticed it with Podcasts locking, and then found that this is consisent with the App Store, and Apple Music. When I try to download any up or update from the App Store, this locks up and shuts down the app. Currently running IOS 8.4.1 on iPhone 6 Plus.

I have performed a reset from the settings, and this was running ok until I opened the app store, or podcast.
