2. Protection Level I Look For
The first thing I check is how much protection the case offers. If I’m clumsy or use my phone a lot outdoors, I prefer a rugged case with shock absorption and raised edges. If I mostly use my phone at home or in the office, I may choose a slimmer case that still protects against minor bumps and scratches.
3. Material That Feels Right to Me
I always pay attention to the material because it affects both grip and durability. Silicone cases feel soft and grippy in my hand. Hard polycarbonate cases give a firmer, more rigid feel.
