I recently observed that my older S10+ captures sharper close-up images compared to the S21 Ultra. Upon close inspection of the S21 Ultra's camera, I noticed the presence of dirt or possibly a glue-like substance on one of the internal camera lenses. This blemish becomes visible when viewed under a torch. I'm confident that the phone I'm using is brand new, came with a warranty upon purchase, and has never been opened or disassembled. Hence, I suspect that this issue originated from the factory during the manufacturing process. I'm left wondering how Samsung could overlook such a detail. To address my uncertainty, I examined several other phones in the market and found that some of them also exhibited the same problem. Could someone clarify whether this is a normal occurrence or a manufacturing flaw?
