So today, I dropped my iPhone 5s on a rock floor without a case on it. The only thing protecting my phone was a screen protector. When I picked up the phone it seemed fine except for some dents and marks around the phone. Later I saw that the screen was starting to pop out on the right side! It stood up from the bezel quite a lot. I popped the screen back in again and everything is working fine. Should I worry about anything now? Or can I just go on and forget this? And yes, I will from now on use a case.
