How to back up your iPhone, iPad, and iPod touch - Apple Support

If you can't update or restore your iPhone, iPad, or iPod touch - Apple Support

Put your device in recovery mode and set it up again

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, but don't release the buttons when you see the Apple logo, wait until the connect to iTunes screen appears:
   • On an iPhone X, iPhone 8, or iPhone 8 Plus: Press and quickly release the Volume Up button. Press and quickly release the Volume Down button. Then, press and hold the Side button until you see the connect to iTunes screen.
   • On an iPhone 7 or iPhone 7 Plus: Press and hold the Side and Volume Down buttons at the same time. Keep holding them until you see connect to iTunes screen.
   • On an iPhone 6s and earlier, iPad, or iPod touch: Press and hold both the Home and the Top (or Side) buttons at the same time. Keep holding them until you see the connect to iTunes 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 the connect to iTunes screen, let the download finish, then repeat step 3.
   
5. After the Update or Restore completes, set up your device.

If you can’t update or restore your device with recovery mode, or you can't use recovery mode because of broken buttons, contact Apple Support.

Yes! I have the exact same problem! And it's a business phone so I keep missing important calls and my callers think I'm ignoring them. Restore as new iPhone doesn't help. Any other fixes???

Considering I paid £1350 for this phone (with AppleCare) it's unacceptable.

Hello I have been facing the same issue. And I have an actual recorded video from my other phone to prove it.

This is unacceptable for an Apple Product and I am really disappointed that I have 2 iPhone X and one of them is having an issue and the other seems ok...

Need a resolution to this Problem at the earliest.

Cheers

this fix seem to have helped. no lag in display on incoming calls for about 12 hours now.

will update in a few days again.

I did the same and installed the latest software in my iphone x via i tunes but it was of no use

As vn u restart the device the problem vanishes but it comes again the very next day

The same problem was back the very next day!

No use..... Problem returns....

Mummy Returns 😆😆😆😆😆

Is it still good?

Did you Restore and re-install your back up or simply set up as new?

Im having the same problem, tried all above but after couple of days same issue happened, no way to solve this except update , changing the phone won’t work

I have the same Problem for over a month. Nothing helps :-(

Having the same problem.....Apple sort it out. Most expensive phone ever having problems. My problem become noticeably different after last iOS update.
