I had been using an iPhone for the longest time and I wanted to get a Samsung phone mainly for the camera. I wanted one with 100x zoom, and while I was browsing I came across an Amazon refurbished s20 ultra for a good deal but I heard from lots of people the s20 ultra have camera focus issue or screen issue with the screen being green and now I am hesitate wether I should get it or not. I had heard many problem and issue occurring on Samsung phone and I want know is there a phone that is less likely to experience or less common to encounter some issue.
