Screen

I have a Samsung phone, and I feel that the screen has a slight flicker. Is this a software or hardware malfunction? How can I find out without going to a repair shop?

What phone
I think you can check by recording the screen and see if there is flickering on another phone

I opened it by dialing *#0*#, then pressed the black box, then pressed the volume down button. A gray screen appeared with circles in it. It was clear at that point that there was a flicker on the screen.
