I've never understood why some manufacturers design phones with glass back panels. I owned a Sony a couple years ago and it made me nervous to use the thing because there were no protective cases available for it at the time. Now I have this S7 which I like a lot, it's a very capable device, but Is there some functional reason for constructing it with a glass back panel? I keep my phone in a two tough, two piece case only taking it out to pop it into my Gear VR once in a while. Reading some posts on this forum describing how easily cracks form cause me concern. My OCD wouldn't tolerate living with a cracked phone even if it's on the back.
