Restored Samsung Galaxy S23+ 256GB S916U Unlocked (Refurbished)

I think the phone would be good if not for the fact that the screen is not flat and screen protector will not fit properly. I have tried three screen protectors and same result with all three. Tried having last one installed by a phone company rep. She said screen is not flat and probably wouldn't get a protector to work properly. She could tell that screen was different as soon as she removed ptotector from screen. Seems that this also has an affect on the way the touch screen works? Contact is bad where bubbles are underneath screen ptotector? I was thinking I could find a screen ptotector that would work? Think now that this a bad (after market) screen on the phone. I do believe the phone was sold as "excellent" condition. I don't consider this "excellent" condition.
