After updating my iPhone it no longer works

After updating my iPhone, it no longer works. There is a notification screen that says "Your iPhone has been updated to IOS 15.8." Nothing works. I cannot even turn it off. Is there another way to turn off iPhone without having to "slide to power off." How can I reset phone?

Perform a Forced Restart on the phone. Follow the instructions very carefully, as this is a bit tricky. You may need to repeat this several times.


Force restart iPhone - Apple Support


There are only 2 possible results when you perform a Forced Restart:


1) The phone returns to normal operation.....or.....


2) There is a hardware problem with the phone that will need attention at the Apple Store (make an appointment) or take the phone to an authorized Apple Service shop.


You can find a list of authorized service shops in your area using the link just below:
