[flagged]
Just for one instance, bug I ran into a few hours ago (persisting in 26.3!) is that, sometimes, you can't even open the lock screen. It just wiggles.
The performance continues to be very poor, rendering far below the 120fps target that iOS 18 hit consistently. This persists with 26.3.
On Mac, the corner handle grab change was a miss but doesn’t affect me much because I don’t do much window resizing.
On my iPad, the fly in and fly out animation for the App Library doesn’t necessarily follow your swipe direction.
I’ve never seen a lock screen wiggle, my guess that might be related to debris or finger moisture more than the OS
I'm happy it's working for you, but it's still an inconsistent and broken release.
There are 10 iPhones in my immediate family orbit, all running 26 (Including an iPhone 12 Pro). Users ranging from their early teens to 90 and I am the one they call when there is any tech issues.
No one is complaining. Not too bad for an inconsistent and broken release.
> "100% usable" is an exaggeration that doesn't describe Apple's Liquid Glass
Only if you define “usable” as “bug free”
Even if true, which I haven't experienced, that doesn't sound like a problem with glass.

Do you realize how tiny of a minority you are in to complain about this, much less even notice it?
I'm not in a minority, this is something that's a new and common complaint among iPhone users. The performance of iOS 26 is very bad. Look at the huge recent spike in "iPhone battery problems" in Google Trends shortly after iOS 26 released, hitting its highest-ever in January 2026. The last peak was in 2011.

And look at how dramatic the graph for "iPhone slow" is. It's the highest it's ever been, by far, seven times higher than the previous highest peak:

This statement lacks perspective. Currently, there are 1.6 billion iphone users worldwide. People who make any complaints about iphone are already in a tiny minority.
Remember in the past, Apple got away with purposely slowing down old models with very little backlash. I dont know, maybe they still do that. So saying "its a common complaint" is completely missing the forest for the trees.
Also the placement of buttons and functionality is completely scattered around the UIs, which severely reduces usability. What do all the mystery meat buttons do now? One has to relearn all the UX. There's a ton of improvement needed, it's about first-draft level quality.
Dark mode UI elements are almost invisible too, frequently.
It has a "my first redesign project" feel everywhere. On macOS I upgraded right away and it was a huge downgrade on performance. On iPhone I waited until 26.2, and merely had to suffer far lower usability.
On mobile that is.
On larger screens with desktops and overlapping windows it looks kind of bad. Not unusable, just annoying. I am hoping this will change as more apps update their design.
On the Mac it’s much rougher than on iOS.
Within an hour of using it, I honestly stopped noticing the differences.
Now I have heard about issues on MacOS and things but not really anything around the phone.
So while it may not be fundamentally broken, it's the type of stuff that would annoy me a lot if I used an iPhone. I never expect to go from a smooth experience to a low-end Android phone experience after a software update.
MacOS... I've avoided upgrading my M4 Max MBP so far after upgrading the M1 Air we have at home. It's just not as smooth as before, even with reduced transparency.
My M4 Air has been fine after the 26 update. I haven’t noticed any difference in responsiveness.
