New Samsung s21 ultra screen broken or damaged?

[Checker2]

Hello guys,

I bought this phone as new sealed phone. Since yesterday it freezes and turns off all the time. 

Is my phone screen broken or damaged?

Thank you

Hi @Checker2.

You shouldn't be having such issues if you've just purchased the phone. Usually, when you set up a new phone, you may need to install new software and update the apps. I'd suggest that you check if everything is updated.

To check for any pending software updates, go into Settings > Software update > Download and install. You can update the apps by opening the Play Store > Tap on your profile icon (top right) > Manage apps and device > Updates available > Make sure the apps are updated by tapping on the Update option (next to each app).

Thank you for your reply.

The phone seems already updated. There is no new Updates for the phone. All apps are also updated. Everything is updated.

What I have discovered is: when I change the refresh rate to 60 hz. It works fine, but 120 hz It doesn't.

Don't know why
