I was using my s21 today and the phone screen went black. I tried to restart it and tried to turn off the phone but the phone isn’t responding. I even tried to charge it, but that didn’t work either. The phone has been restarting itself every time the phone freezes for the past few weeks, so I don’t know if these two issues are related to each other. I just need help. I am currently waiting to hear from customer service soon. Thank you

Have you tried a soft reset? It’s the Android equivalent of a Windows Alt-Ctrl-Del.
Soft reset with hardware keys
A soft reset is a simulated battery removal. This is used to power a device off when the screen is frozen or unresponsive and the device it has an internal battery that cannot be removed. It does not cause loss of personal data on the device.
Press and hold the Side key and Volume down key for up to 45 seconds.
Wait as the device restarts.
