it does not bend more easily then the scrapphone 6+ the test was made with the normal scrapphone 6
As old hat as the i6+ is (Basicaly a note 1 in a bedable metal shell with a big set of bezels.) it has supposedly sold a lot, so if there's any justice this state of th art phone should sell colossaly.
Apparently both the front and the back of S6 Edge is made out of plastic. Samsung is still using plastic!
Front is made by a plastic substrate as mentioned in the article
So they are using some sort of plastic-glass composite that easily gets scratched like plastic and is easily breakable like glass.
Notice how the back cover despite being bent so badly doesn't shatter/break. This elasticity can only be achieved by polymers and not by pure glass!
