I recent installed IOS 26, with my iphone 15 as a machine. I am experiencing glitch on switching apps, switching users in a specific apps.
Delay is also visible when unlocking the phone, typing, touching the screen, going back to the previous app (clicking the arrow button on the top left). When using a two fingers navigating the phone, the other finger is unrecognizable when clicking on to something.
Overall, UI were elegant and amazing. Please fix the responsiveness and may consider lower versions of iphone when possible.
