I do have a case and it's a pretty bulky one. My friends say that it looks like a brick because of it. It has a rubber cover and a plastic plate on the back. I don't think I would ever trust myself without one. I always drop my phone when I am taking out my wallet and there have been numerous times where it would be have been shattered if it wasn't for the case. Does it make my phone heavier and bulkier? Yes, but I value the safety of my phone over comfort.
