It’s funny how different people with the same exact device and firmware can have such different experiences. I’ve had nothing but a smooth experience so far with iOS 13.... literally the only issue I had was the mail.app crashed on me once while forwarding a message.... I reopened it and it worked.
I haven’t installed iOS 13 because I’m not a developer.
If I was, I wouldn’t be installing a beta 1 on my primary device, it would be on a secondary device used for testing where I would report bugs using the Feedback app.
not sure why you have quite a few problems.
My experience is not stellar but decent enough. Some mail app not updating emails, music app working weirdly, respiring and several crashes apps. But overall can’t complain a lot.
Technically, the chip on each device has its own defective spots. Through normal use, fine, but in beta testing, something unusual could be triggered. Hence “random bugs” and worse experience on certain devices than others.
Well, it is Beta 1. Lol. It wasn't expected to be without bugs. Perhaps you should have waited until the Public Beta in July, which is what Apple wanted non-developers to do...unless you are a developer?
