iOS 26 B3 has been pretty rock solid for me, with very few issues when it comes to stability. No OS crashes; the only app that has crashed, and quite regularly, is Candy Crush, so no big issue.
The one improvement I wish they would do is improve the laggy and stuttery UI. This is never an issue in apps, but the phone’s UI feels terrible to use and this is on a 16 PM. I know it’s a beta, so I expect issues, but iOS 18 B1 wasn’t even close to as bad as this. It is getting a little smoother on each release so that’s a good sign.
