So you do something abnormal with the intent of showing a bug...
It's not abnormal. I found it because it happened for the first time by accident after I pulled down Notification Center and I didn't know why my home button wasn't working right. I eventually found out how to do it every time.
I've never had any of those issues shown in those YouTube videos. I actually think ios 9 runs really well. Very rarely have I seen a bug and even rarer where it has bothered me, especially like your over reaction.
I'd argue that I'm not overreacting since iOS 9 was expected to be an update focused on performance and refinement. It shouldn't be a regression in quality if they're calling it the opposite.
Of course you don't and you wonder why your videos garner dislikes.
Some of the bugs you've uncovered will never show up in day to day usage. You can report them and if Apple feels they are urgent enough to address, they'll address them. Kudos you found them, but there are bugs that most likely have a higher priority.
The first one managed to show up in my day to day usage which is how I know about it. Arguing they're not urgent is ridiculous. Imagine someone not as much of an enthusiast as me doing one of them by accident, wondering why their phone isn't responding normally. That's supposed to be fine? What kind of known bugs should be a higher priority than ones that lock you out of the phone and warrant a force restart? Other obscure bugs?
If your initial response is to downplay what I told you about these
major bugs, think about the side you're taking on the issue. Are you advocating ignoring these bugs? Am I supposed to treat this like the new normal? It wasn't like this before iOS 7 and there's no reason I should lower my expectations from Apple.
And if you argue "it's a beta!!", it would be different if I was talking about iOS 9 Beta 1 like this. Apple have already made public iOS 9 releases with these same quality issues.
