Ok, so after a long thinking and being worried about the bendgate etc. I decided not to wait for 6S and bought the iPhone 6 to upgrade my ageing iPhone 4. It arrived after few days and I was super excited. Started setting it up and noticed the top part of the display had yellowish tint whilst the rest of the screen was cooler. After thinking whether or not I should keep it I decided to change it. Ok, got another one after few days and everything looked perfect. I was pleased that display is great and even, no dead pixels etc. so I was very happy. Well, until I used the mute button. Which just doesn't work correctly. Sometimes I move it to mute position but it doesn't switches so i have to readjust it again in order to work. So, tomorrow calling Apple and hope they will still make it before xmas. Anyway, other than this I think the phone is great. I have a feeling that the bending I was worried about is actually really just a media bubble although I did babied the first phone a lot. Will report later with more experience but for now this is it. Hope 3rd time the lucky will apply here.
