Samsung Galaxy Note 20 128GB Bronze, Unlocked

So i just got this phone a few days ago, havent dropped it or anytbing but i glitches very often, its like the screen shifts over and it messes up the color when it does that. its very annoying and i basically went from one broken phone to another broken one. I updated it, restarted it and that didnt help. the only way i can get it to go away is shutting off my phone and turning it back on

First let me give the Pros'. The phone came in a very good condition, the camera quality is excellent, love Samsung products but the con is that I ordered an unlocked phone and my mobile data never worked. Mobile data never came on, I had full service but to say use internet other than Wi-Fi it never worked. I rebooted the phone, I brought it to the local stores so i could have it fixed, they all said the same thing they can't assist me, suggesting the phone has a glitch. I am an international buy and it's expensive to have it sent back, so I had to consider this as a loss.
