At school, I keep my iPhone in my backpack. So today, I went to the cafeteria, and I set my backpack down where my phone inside was at the top. Someone walked by, and stepped really hard right on where my phone was. It was a 6s in an Otterbox Defender case. I haven't taken it out of the case yet, but I'm worried that there was bending or internal damage, or any damage causing unresponsiveness to the screen. Is it possible these things may happen?
