hello I have an ipod 7 touch and my screen is flickering

Try to give it a reboot by holding down the sleep and home keys for 20 seconds or so. When you see the silver apple, let go and let it reboot. If that doesn’t work, then make an appointment at an apple store or authorized service provider and have them check it out, because the screen should not be flickering. Get it taken care of while it’s still under factory warranty

This might be a hardware issue. Go to the Apple store and get it checked out
