Agree about the screen size
I totally don't understand this fascination that smartphone manufacturers have with these enormous screen sizes.
Back in April I picked up an iPhone 6 (not the 6 plus) thinking that finally I'd have an opportunity to discover the large screen delights that Android users have had for years. What a mistake. The thing is totally unbalanced in my hand due to the size, it's awkward to pocket, and just plain irritating to use because of it's size. Not to mention the battery is shit.
I used it for a month and then went back to my iPhone 4S, The 6 now lives in my back only to operate as a hotspot and as an oversized iPod (unfortunately my music collection is well over 64Gigs).
I'd be well up for a powerful Android phone if it was done in a 3.5 - 4 inch format. Anything else is just to big to be useful as a phone.
