I simply can't understand threads like this one. You apparently can find nothing positive to say about Apple, iPhone or iOS so why not switch to a different operating system that better fits your needs/wants. Coming into an Apple forum and saying things like the changes are stupid or there is no valid reason for certain changes are just your opinions. I'm not trying to criticize you, I'm just trying to understand what you are trying to accomplish.
So I'll validate you in that I like that Apple let's me force apps to only use location when I use them. Not forcing "always" or "never".
Also the one that I can finally stop being begged to rate apps, although that should've been off from the start, I instantly one star any app that asks for a review more than once.
There's also the regression that the toggles in control center not turning wifi or Bluetooth off according to motherboard and Apple's documentation they just disconnect, not actually turn off.
I've said they're opinions, but when I got calls for Apple, stuff like this was the main reason most people didn't upgrade.
And to the opinion guy, I never intended this to be fact. It is fact that I think it is stupid. And it is fact that I haven't seen any justification for these UI changes. It is also fact that again, most of the people I spoke with working for Apple, didn't want things to change when they upgraded.
I don't see any advantage to a big notice for "messages" or "settings" that was an intentional back step. Same with them onboarding me on apps I know after the upgrade.
I carry two phones actually and my second is Android. That doesn't negate the fact that a device I paid significant money for had features changed/regressed for no reason with no recourse.
Glad someone seems to have said Apple will sign a downgrade. I'm just unsure if I can since they kind of forced me to "upgrade" iCloud, not sure it works with iOS 10. Plus, Apple doesn't bsckport security fixes, so I either have an unsecure phone, or deal with their stupidity.
