Have used a case ever since the iPhone X. I’ve had a couple of unexplained cracks, like super tiny barely noticeable cracks near the top of the phone of both the 8 plus and X. I don’t think I did anything to cause them honestly, at least nothing sticks out in my mind. The size of the cracks and location don’t make much sense either. But ever since just in case I used a case. This year I’m gonna try a mix. I’ll have to use a case when at work. I’m in the construction field, it would be pretty hard not to damage the phone for me or that reason alone. When not at work though I’m gonna attempt caseless. Going to give screen protectors another shot as well. They've never worked out for me in the past, but would be great to protect the screen from all the sand thats inevitably going to end up around it. I love the design too much to keep it buried in a case.
