Same thing happened to me. My two year old was sitting in my lap, using the phone for two minutes. When I took the phone back the cover was cracked. He didn't leave my lap, or drop the phone. It was obviously cracked from him squeezing a little too hard when using it in kid mode. This kid can't muster up enough strength to pull apart the plastic tabs on a piece of string cheese, how on earth was he able to crack the lens cover? Answer being it's too big and too thin. I've had iPhones that have been through !@#$ and never did a lens cover crack because it's a 1/4 of the size and made of a durable material. Back to Apple I go.
