Frozen Apple logo on white screen with loading

I failed to imagine it the first time but I'm pretty sure now that your iPhone is updating and it is stuck on the update. I found an article that may help you. Refer to the links below:

If you need more help

Contact Apple Support to set up service if you have any of these issues:

• You still see a black screen after charging, force restarting, or following the steps in this article.
• You see a black screen, but you can hear alerts, sounds, and vibrations.
• The screen remains black, but the device chirps when you unmute it and connect it to power.
• Your screen is on, but it doesn't respond when you tap, slide, or try other gestures. 
• You can't force your device to restart because a button is broken or stuck.
• Your device is stuck on the Apple logo, displays a solid color, or isn't recognized in iTunes.

Note: Apple may not respond to your call because of the COVID-19 issue but you can try.

If your iPhone isn’t working right, try restarting it. 

How to restart 

1. Press and hold the Sleep/Wake button until the red slider appears. 
2. Drag the slider to turn your device completely off. 
3. After the device turns off, press and hold the Sleep/Wake button again until you see the Apple logo. 

Hope it helps!
