the ios8 issue needs resolving but I don't think the phone is the blame but rather the software, disregarding that, the bend issue with the iphone 6. Well use some common sense, you don't buy a 5.5 inch phone, put it in the back pocket of skinny jeans and then sit on it, it will most likely bend a clear example here: http://www.cultofmac.com/297404/get-bent-shocking-history-bent-smartphones/ All I'm saying is take proper care of your phone and it won't bend but don't hassle the Iphone 6 over being cheap, you just don't know how to take care of stuff.
just to say Samsung S5 user here, so don't call me a 'sheep' or anything
