If pulling a case off of any other phone wouldn't bend it then it shouldn't bend the iPhone. Perhaps it does, but it shouldn't. My whole thought about this bendy thing is that, yes, a phone can bend but that the iPhone shouldn't bend any easier than say...a Note Edge, Nexus 6, or any other device. However, you're not reading reports of these phones bending.
This leads me to believe that my iPhone 6+ does, in fact, bend easier than other devices. Yet it cost the same or more than other devices. Shouldn't it be as durable, or more-so, as its competitors under the same conditions, not less?
I like my 6+ fine but the fact that I have to consider whether or not its going to bend under normal conditions, like removing a case, is simply not good. I believe Apple will address this in the next version. ...in the meantime I'll have to keep trying to be extra careful.
