After years of trouble free iPhone's quite honestly I'm shocked how bad my iPhone 6 Plus really is.
Again I stress I'm NOT bashing Apple, just relaying my experience.
Frequently crashes when using any app or browser. In addition so many other issues it's too long to list. Apple replaced my first pre-ordered iPhone 6 Plus, yet this one is only better from a hardware standpoint. The first one bent, and I'm extremely careful. I've never used or needed a screen protector as an example and never scratched a display. That's spanning 9 years and over 61 phones. I take exemplary care of all my tech gear.
Software, Apple has always shipped excellent OS's. I've bought nearly every new Apple laptop since 1991, oh sure they initially have some small bugs and that's to be expected. I'm a high tech engineer of twenty years I don't expect perfect software. Yet since 2012 Apple has learned what customers will tolerate and still keep buying, so Apple now ships to that lower standard while profiting off "it just works" slogan that's a thing of the past.
Where Apple chooses to go from here remains to be seen. Proof positive that they admit there's problems is a statement they made saying iOS9 focus is improving quality. I'll believe it when it happens.
