Yeah I have heard the same thing, and whilst the glass on the back of my S6 has not been scratched or cracked, the glass on the front cracked in two places with very little pressure.
Lent up against a set of chest of drawers with it in my pocket, forgot it was there to be honest and the handle, on the draw cracked the screen in two places.
I bought a replacement front piece of glass for it of ebay for £10, but I need to get a decent suction cup to take the back, off as the one provided in the kit won't stick to the back enough to lift the back, up enough to get something under it.
Either way with the state of the S6 which at first was great, but suffered so many performance drops, signal issues etc that it has put me off them.
There are a couple of phones that I have got my eyes on, LG G5, Lenovo, Xiaomi and to my suprise the HP, but I will see what they are like from streams and youtube videos from MWC.
