Well, I have iOS 11 on multiple devices and have friends with iOS 11 and I’m seeing (and hearing about) launch lag and the calculator button problem but not your other issues. So this isn’t simply an iOS 11 problem you can do nothing about besides complain on the internet.

I mean, if that’s what you prefer to do, be my guest. I don’t mind at all. I’m just pointing out you might be able to do something about some of the problems.

Also, I didn’t say it was your fault. I get that you’re frustrated, but it doesn’t help to get angry, especially with people who are trying to help you.
