Hey, I hit my phone pretty hard on a hard desk surface while i was holding it, it just slipped my hand and i tried catching it but made it go faster by hitting it while it was on air with my hands. yeah, that happened. It was also charging thru usb/power cable. Now, I checked the surface of the phone where it hit, there seems to be no scratches or bruises. This is pretty strange. And phone is working well. Is there a possibility that it'd cause a problem later? What would be the concicoenses of hitting a phone by near its speaker area to a hard surface? I am a little paranoid. Thank you.
