Seems I’m not the only one being cautious. After some less than perfect iOS updates I figured I’d wait until as least iOS 11.1 before I’ll update. Reports of app slowdowns and performance drops suggest I’ve made the right decision for now.
Apple have already released iOS 11.0.1 Update With Fix for Exchange Email Bug just a week after the iOS11 release.

While talking about iPhones it appears the are some issues with the new iPhone 8. Apple are working on a fix for an issue causing some iPhone 8 and iPhone 8 Plus owners to hear intermittent crackling noises when using the device for phone calls, the company told The Verge in a statement this afternoon.

"We are aware of the issue which is affecting customers in a small number of cases," said an Apple spokesperson. "Our team is at work on a fix, which will be included in an upcoming software release."

YouTuber JerryRigEverything did a drop test on the iPhone 8. It survived a drop from knee height and was okay after one fall from waist height because it landed on the aluminium frame, but the glass broke after a second waist-high drop.
 

Another drop test that compared the iPhone 8 Plus to the iPhone 7 Plus, the iPhone 8 Plus shattered on the first drop.
