Understanding My Needs

When I decided to buy a phone case for my Samsung S21 Ultra, I first thought about how I use my phone daily. I needed a case that could protect my device while still looking good. I also considered whether I wanted a bulky case for maximum protection or a slim case that wouldn’t add much weight.
