S21 Ultra Black Screen

[Members_0alpcah]

The other day when on about 14%, my Samsung Galaxy S21 Ultra randomly turned off. I thought nothing off it, put it on charge and left it. It was only when I went back to it that I realised something was wrong. After holding down the power button, I got a vibration but nothing appeared on screen. The phone vibrates when I plug in a charger but nothing on screen. I've attempted a soft restart with Volume Down + Power Button.

Is there any solution to this? Will a screen replacement fix the issue or is this not the case?

Thanks.

A Samsung Galaxy S21 Ultra might have a black screen due to a software glitch, an incompatible app, or an operating system update. To fix this, you can try restarting the phone, charging it, or performing a factory reset
A factory reset would be a last resort as would possibly lose contacts and data but may fix your issue
