We are striving to creating cell phone cases that will protect your devices as much as possible, the most likely scenario is that your device falls in a corner where the force applied to the glass is more concentrated. At the very least, you need a case that uses a shockabsorbing material (such as silicone or rubber) and protects the corners of the case. If you're feeling confident, a thin, unobtrusive case from a manufacturer like WJM would be just what you need. WJM could also guarantee certification as your request such as RoHS, FDA, LFGB.
