IOS 27.1 touch response issues and laggy contact searching

iPhone 16 with iOS 27.1 becomes unresponsive to touch to execute a command in any application. It usually occurs frequently, appears all of a sudden, and sometimes it takes too long to search for a contact from the saved list. When the contact is found, we can't make a call because the call icon bar does not register touch input; the only option is to go back to the home screen by swiping. This is a bug that needs to be addressed in the next update.

What troubleshooting steps have you performed? You may just want to contact Apple Support.


Please have Apple perform diagnostics on your iPhone. It can be done in person at an Apple Retail Store or at an Apple Authorized Service Provider. You can also contact Apple Support and request remote diagnostics.

Same exact issue since iOS 27. Phone isn’t even a year old either. So sick of regression like this.

The small number of complaints indicates a rare combination of circumstances.


For example do you have two or more accounts turned on for Contacts in Settings, Apps, Mail, Accounts?

While I have sympathy for your problem, keep in mind that is is a problem with your iPhone specifically, not with hundreds of millions of other iPhones, so you need to troubleshoot the problem (or contact Apple to help).


It would be helpful if you describe your issue specifically, because “same exact issue” is meaningless, as there have been several issues discussed in this thread. And also describe the troubleshooting steps you have taken, so other helpful users in this community can provide guidance that doesn’t overlap with what you have tried.
