User might be caught in a Guided Access page with error like this when they trying to leave Guided Access. Please pardon me for shotting a photo with phone to show this condition, because I can't even get a screenshot with home button and power key pressed together. I can't lock the screen with power key or by the magnet sensor, can't get back home page with home button. The ways to exit is waiting for the exit button might could use, or the screen shutdown, or enforce the device to shutdown. After exit the Guided Access without rebooting the system, the Guided Access would be freezed for minutes, noticing the Guided Access can't be used. In iPadOS 26, since, I can prove confidently, 26.5beta1 even earlier, could discover that issue. The problem could happen several times in a day. I have raised that issue since April 25th and the ID is FB22608734, which has more than 10 similar reports. To say something beyond the issue, actually I guessed that my device, iPad mini 5th, might can't get the update of iPadOS 27, so I hoped that Apple Developer Teams could at least fix those annoying problems. Actually there is a long list in Chinese with problems summarised by some Chinese User I waited for a long time for a miracle in WWDC 27. But that's a miracle.
