iPhone users complain about annoying errors after updating iOS 27
(Dan Tri) - Some iPhone users report that the touch screen is sometimes unresponsive, the device lags, and is less smooth after updating iOS 27. Apple has not yet confirmed the cause of this situation.
The screen sometimes does not accept operations
After iOS 27 was released, some iPhone users began reporting issues related to touch screen responsiveness and interface smoothness.
According to TechRadar, complaints appeared on Reddit and several online forums. The most annoying problem is that the iPhone screen sometimes does not accept touch operations.
Some users reported that the iPhone still works normally most of the time, but sometimes the screen does not respond to touch operations in some areas of the interface.
In case the error appears while using the app, some people say returning to the home screen and reopening the app can get the touch working again.
Restarting the iPhone is also shared by many people as a temporary solution. However, this method does not completely solve the problem because the problem may reappear.

Besides the touch error, some iPhone owners also reported a lack of smooth interface after the upgrade. Animations can be choppy when swiping or switching between screens.
Notably, a Reddit user discovered this phenomenon on their device seems to be related to the number of app icons on the home screen.
When a page contains about 30 icons, the animation becomes less smooth. After dropping down to about 20 icons, the condition improved. However, TechRadar notes that this is only a solution discovered by users, there is no evidence that the number of icons is the general cause of the problem.
The cause is unknown
Another possibility is that the iPhone is still performing background tasks after upgrading the operating system.
After major iOS updates, it may take time for the device to complete data indexing and other tasks. During this time, performance or battery life may temporarily differ from normal.

Currently, Apple has not confirmed that this is an iOS 27 error, and has not announced the specific cause or patch.
Therefore, it is not possible to determine the exact scope of impact or which iPhone models are more susceptible to problems. The feedback on the forum is not enough basis to conclude that the error appears on all devices running iOS 27.
What should users do?
If you have upgraded and the touch screen is not responding, you can try restarting your iPhone. If the error only occurs in one application, exiting to the home screen and reopening the application can also help temporarily fix it.

With post-update lag, users can wait longer for the device to complete background tasks and update applications to the latest version.
However, errors are only being reported from a portion of users. In case the problem originates from the operating system, users may have to wait for the next update from Apple for a more thorough solution.
