I installed the 26.1 beta on my iPhone 11 Pro (which I use as a developer) and, honestly, the release doesn't present any major instability compared to the 26.0 public version (aside from the bugs already reported in this thread). However, the liquid glass is again too pronounced and makes the outline of icons, commands, the settings menu, etc., too noticeable, and it seems like we're back to the first betas of iOS 26. I don't like this because it makes the UI very artificial and I don't understand what the point is!? Perhaps Apple wants to experiment with an interface with the ability to "adjust" the liquid glass effect? If so, I could understand it. If, however, they wanted to keep this interface, then I wouldn't like it graphically. Without further ado, Apple should have spent its developers' energy making iOS 26 more stable and fixing the various bugs reported by those, like us, who volunteer to test the betas! But, then again, I'm certainly not a computer engineer who can comment on the usefulness of this beta interface! Obviously, I don't intend to install this iOS 26.1 beta on my iPhone 15 Pro (which I use as my primary phone).
UPDATE: After a couple of days, I'm finding the iOS 26.1 beta to be slightly slower (benchmark) than the official 26.0. However, based on the benchmark data, it still seems smooth. To reduce this liquid glass effect around icons or buttons, which is more pronounced than in iOS 26.0, you need to go to Settings > Accessibility > Display and Text Size and disable "Button Shapes" and "Increase Contrast." This makes the liquid glass appear less pronounced, and in my opinion, I like it better.
They haven't fixed the problem of finding events with the magnifying glass in the calendar, and for some, voicemail doesn't appear in the Phone app bar (in my case, it does). Many of the previous bug reports reported in this thread remain, too!
