Forums like this blow everything out of proportion when they generally only effect a very very small number of people. Then people get all up in arms talking about how Apple quality is garbage and how they aren't fixing some huge problem that few are truly experiencing.
Exactly. Not only that, but it's blowing an "issue" out of proportion that no one even knows what is causing it. 128GB iPhones? Large app libraries? Restored from an old iPhone backup? No one knows, but everyone instantly assumes that Apples QA department is to blame or that Apple can no longer make devices that work.
Software design is difficult. Hardware design is difficult. Put them together and what do you get?
I agree that very often the reason of these "flaws" is user error. But not always. And can it really be said that if a problem only affects a small percentage of the users then it's a small issue or not an issue at all? Yes, these articles often blow up things. But is that really a bad thing? I'm pretty sure that after the 'bend-gate' Apple's engineers instantly started to work on the modifications they should make to the 6S Plus to reduce the likelihood of this happening again.
