This is really surprising as The screen was working perfectly before the software update started , I was the one using the iPhone 12 before but I gave it to my brother when I got a new one

Another thing to try is a Force Restart.

• Press and quickly release the volume up button.
• Press and quickly release the volume down button.
• Press and hold the side button until you see the Apple logo

This usually means an issue with the iPhone screen digitizer, and that it needs to be replaced. Note that the iPhone 12 isn't "new" and that you should take it back to whoever you purchased it for a refund or exchange.

Otherwise, make an appointment at your nearest Apple Store's Genius Bar or an Apple Authorized Service Provider for service.
