I Face Back Cover Separation and Possible Battery Swelling on Samsung S23 Ultra

My Samsung S23 Ultra has started to show a serious issue—the back cover is coming apart, and I suspect that the battery may be swelling. This is especially frustrating considering that the phone is marketed as a premium, top-tier device and is still under warranty.

As a consumer, I take great care of my phone. I have always used it with a protective case and screen guard, so there is no misuse on my part. It is disappointing to see such a problem in a flagship product within such a short time.

I am requesting a full product replacement under warranty, as this issue clearly indicates a manufacturing or hardware fault. I expect Samsung to take responsibility and resolve this matter quickly.
