Hello, I would like to report a compatibility issue that appeared after updating to iOS 27.
I am using an iPhone 17 Pro Max. After updating to iOS 27, when accessing a specific third-party video website through a VPN, accidentally tapping a video thumbnail causes a gray loading bar to appear. Once the loading finishes, a video preview immediately pops up, after which the entire device becomes completely unresponsive and can only be recovered by force restarting the iPhone. The issue can be reproduced approximately 8–9 times out of 10 attempts.
This issue did not occur before updating to iOS 27. I also have an iPhone XR and an iPad, and the same website works normally on both devices without automatically displaying the video preview.
On the iPhone 17 Pro Max, I also tested the website using other browsers, and the device still became unresponsive. However, I have not encountered the same issue when testing other video websites so far.
Relevant websites:
https://up.9p58b.com/ (accessible directly in mainland China)
https://91porn.com (requires a VPN)
I am a user in mainland China. Due to the sensitive nature of these websites, I would prefer that other users not be asked to visit them specifically for testing purposes.
At this point, I cannot determine whether this is an issue specific to my device, a website compatibility issue, or an issue with iOS 27 itself. I hope Apple can investigate and record this issue.
If this is confirmed to be a known iOS 27 or system compatibility issue, I hope it can be addressed in a future software update. If it is determined to be an issue with the website’s own compatibility, it would also be helpful to know that, so that the source of the problem can be better understood.
I would appreciate it if someone could respond to this post and let me know whether this issue has been encountered by others or is already known to Apple.
Thank you.
