I feel like we get things like this with every new phone, but... I’m noticing frequent stutters/hitches when closing apps. It seems happen when opening and closing an app that hadn’t been in the background, but not always. I’ve had the phone for 2 days now, so I’d hope that any slow performance due to background indexing or whatever would be done by now, but maybe not."
