It's not a matter of holding the iphone 13 Max wrong and if you are using a military grade Iphone 13 Max case with the sliding camera protector and the built-in ring stand, this type of case is obviously bigger than the iphone, which means the sharp edges are even worse. But I do see some cases, which do have rounded edges, however, these cases appear to not be as good as the military square (sharp) edged cases in terms of protection. I will never buy another square edged iphone again.
