First of all thanks for sharing your experience with your new phone, I'm not sure, but is it a 6+ you have there?
I think its time for an idependent company to make some objective structural stress tests to see how fragile the new iphone 6(+) really is, especially compared to the previous iphones and its competitors.
Just to give my subjective opinion. Its now 3 days after release and while there are lots of happy customers out there, I also see a lot stories of
- slippery phone (leading to cracked displays)
- breaking very easy when using little force (see PD13)
- bending phones in pockets
- clicking display glas
These are all issues that might be related to a fragile (very thin) design...
I also want to say, that its very positive that Apple is replacing all phones without questions asked!
