iOS 11 incredibly slow on iPhone 7 Plus

So frustrated - iOS11 installed perfectly and works great on my iPad Pro. Installed on my iPhone 7plus (with 90GB free space) a few hours later and the phone is essentially unusable. The install went OK but when I click on any app (3rd party or native iOS - like Mail or Messenger) - there is a 20 second delay before the app opens. Unable to make or receive phone calls, texts.


Reset network settings, then all settings, then a complete erase / restore - still slow as Christmas. My phone, at this time, is essentially useless. Google Searches don't show this as a common problem - I'm hoping someone here has experienced this and has a suggestion?

iPhone 7 Plus, iOS 10.2

I'll join the choir.
I have the exact same problems on my iPhone 7 (128 GB): Extreme lag, no sound, no vibration. I've tried reinstalling as new phone without it helping. Rolling back to 10.3.3 gave me a working phone again.


Please fix this ASP!
