There are many ways to fix an unresponsive message iPhone displayed, since the cause of the error is known. Lately iPhones have been susceptible to many security and software bugs. Last month, Apple released iOS 15.3 with dozens of fixes, including dangerous IndexedDB API issue that allowed malicious websites to access users’ browsing history.
Likewise, there are a few errors that seem to reoccur. For example, the “Last line is no longer available” error runs in iPhones since 2018which also happens to be the year that Apple launched its iOS 12. Virtually all iPhone models that come with an e-SIM are vulnerable to the error, but there are several workarounds that can fix it.
A iPhone the screen may stop responding to touch for a variety of reasons, including a software or memory problem, damaged system files, improper placement of a screen protector, moisture on the screen, and more. Fortunately, in most of these situations, users can fix the error. For example, if a iPhone screen not working properly following applying a screen protector, it is best to remove it. Although users can easily remove some screen protectors by pulling from a corner, it is best to have them removed by a technician to avoid possible damage to the screen. Similarly, iPhone screen may not respond to touch due to dirt or moisture on it. In such cases, wiping the screen with a clean microfiber cloth or screen wipe will help resolve the issue immediately. Apple is selling a cleaning cloth for $19 also for all its devices.
Force Restart on iPhone to Fix Unresponsive Display
Several users have linked the iPhone screen error to the unavailability of storage on the device. The underlying assumption seems to be the storage requirement to run an application with all the necessary resources. When storage in an iPhone is turned off, apps may not be able to run properly and they freeze, leaving the device unresponsive. In such cases, freeing up space by deleting unused apps or moving heavy files such as pictures and images to a secondary device can help users. If the problem has begins to occur following an incident of accidental physical or liquid damageby contacting Apple Support for iPhone display error will be the best option.
