iPhone 15 Freezes and Lags Constantly Since the Day I Bought It

I bought my iPhone 15 on August 19, 2024, and from the very first day, I've been experiencing freezing and lagging problems when trying to take photos. I'm really disappointed that I can't take photos properly anymore, especially considering this is a new device of such high quality. While using it normally, without any demanding apps or games, the screen unexpectedly freezes, turns black, and then the Apple logo shows up. The frequent freezing issues have left me reluctant to use the phone for taking photos or even for simple tasks. This ongoing problem has made me doubt the quality of the device. I am looking for a replacement or a satisfactory resolution to this ongoing issue, as it is not acceptable for such a recent purchase.
