iPhone 7 Keeps on freezing

Hi, I had the same issue and i SOLVED it (finally).... I used the Truecaller app which created a "SPAM" contact which contained a LOT of blocked numbers which was causing the " Call Blocking & Identification" setting to freeze. I couldn't just delete the contact because it got stuck every time I wanted to open it. SOOO i had to go to the Truecaller app and go to Settings>Top spammers> and disable the "Store as contact" option. Then I had to Deactivate my account by going to Settings>About>Deactivate account. After I did all this I was finally able to get into the Call blocking menu 🙂 --- I have a 7 Plus 256 GB

1. Make sure that you're using the latest version of iTunes.
2. If iTunes is already open, close it. Connect your device to your computer and open iTunes. If you don't have a computer, borrow one from a friend or go to an Apple Retail Store or Apple Authorized Service Provider for help.
3. While your device is connected, force restart it with these steps:
   • On an iPhone 6s and earlier, iPad, or iPod touch: Press and hold the Sleep/Wake and Home buttons at the same time. Don't release the buttons when you see the Apple logo. Keep holding both buttons until you see the recovery mode screen.
   • On an iPhone 7 or iPhone 7 Plus: Press and hold the Sleep/Wake and Volume Down buttons at the same time. Don't release the buttons when you see the Apple logo. Keep holding both buttons until you see the recovery mode screen.
     
4. When you see the option to Restore or Update, choose Update. iTunes will try to reinstall iOS without erasing your data. Wait while iTunes downloads the software for your device. If the download takes more than 15 minutes and your device exits recovery mode, let the download finish, then repeat these steps.
   
5. After the Update or Restore completes, set up your device.

I have the same issue with my iPhone 7 Plus 256 gb in Gold. It freezes constantly in many apps. It happens every time I type something in multiple apps. I have done a soft reset and a factory data reset. It is still happening. I am very upset and disappointed because I have almost every single apple product they make (minus the watch because it has to be tethered). My iPhone is still under warranty, obviously. Should I replace it at the Apple store with a new one or is there going to be a fix? I am tech savvy and have done every and all fixes related to this issue that others have been asked to do and still not working properly. What is Apple doing and what should I do?

What I noticed is.. after the device has been unlocked, SEEMS iPhone is not responsive to touch input and eventually the app that is currently opened will crash. This happens maybe 5 times in a day.

Same problem here with iPhone 7 plus. Tried the suggested fix several times last week and no luck. 😟. Probably going to need to replace the phone.

This problem was never fixed!

I have this same issue on my 7 Plus. Has anyone figured out a fix. It is annoying.
