S21 ultra screen unresponsive

[dyslexic]

**Background**

My father came into my room, saying my phone wasn’t working. (He’s not very good at understanding technology.) So I took the phone, and his screen didn’t recognize it being touched. Even the fingerprint sensor didn’t recognize it being touched. Luckily, its an S21 Ultra, and that has a pen, and it fully works with the pen. So now he can only use his whole phone using a pen. (Please help.)

What i did to try and solve it

-Updated software and apps

-Restart 

-Backup everything 

-factory reset 

Even after a factory reset it didn't work even made a new account thinking it might be a setting linked with his account 🤔

 Too Samsung administration 

I did do the Samsung Members' diagnosis, and only the fingerprint didn't work and the touch screen part 

His phone screen isnt cracked or damaged other than minor scratches

I would say just upgrade him to a newer phone if possible.

Possible issue with screen. ( loose screen contacts)

Is the back cover fine? ( mine came loose after almost over 4 years of having it now)

After factory reset I would normally not recover apps and settings just to eliminate bugs. Rest can be recovered.

Try under support section of this app and diagnostics that will show any issues

I said I already did that

Sorry, I meant S22 Ultra. He's only had it for a year. I don't understand the last part of what you said. I factory reset his phone because I couldn't figure out the issue, but it didn't work anyway. The back cover is just fine. It sounds like you're referring to an adhesive issue, and I don't see how loose adhesive would affect it.

I don't see how you can lose all screen contacts at once, but I do understand that sometimes you're just unlucky like that. 😞
