I upgraded to the S21 Ultra from a Note9. I was looking for a phone with a similar size and weight, but with much better camera features. I don't know if this is a software issue, but there are often times with the S21 Ultra where the camera simply does not focus, which is infuriating when trying to capture a candid moment. I never experienced that with the Note9. I've also found that a lot of indoor pics at even 3.0x are splotchy and not at all sharp. Before you ask, yes I did remove the film from the camera lenses after unboxing. I haven't changed the camera settings from the default, so maybe that is where the problem lies.
