Well if your pants are skin tight and there is no room in the pocket, I can see that happening. That was cool when I was in high school and wouldn't wear a pair of jeans that I didn't have to lay down to zip and could only zip with a pair of pliers.
If I carry a phone in my pocket now, it's usually my front pocket and I no longer wear painted on jeans. There is sufficient room for my phone to travel safely. 4951
