Have you encountered the problem of your iPhone screen or display not turning on during a phone call? This problem is not specific to a particular iPhone model, and some users experience it after recent software updates. In this article, we will suggest four troubleshooting steps that you can try one by one.
The first troubleshooting step is to go to the Settings app, navigate to Accessibility, and tap on Touch. Scroll down a little bit to see “Prevent Lock to End Call,” a newly introduced feature in iOS 16. This feature terminates the call when you press the power button once, preventing disconnection of the call when not connected to any Bluetooth headphones or headphones. Try turning this feature on or off and then check whether you can access the home screen when you press the power button while on a phone call.
If the problem continues, you can try the next troubleshooting step, which is performing an all settings reset. Navigate to Settings application, tap on General, and scroll down a little bit to access “Transfer or Reset iPhone.” Tap on Reset and then perform “Reset All Settings.” This step will not delete any data but will perform a reset of any settings changes.
The next important troubleshooting step is checking the proximity sensor. If the top section of your iPhone got hit by any chance, a proximity sensor hardware-level failure could have happened. You can check whether the proximity sensor is working perfectly or not by placing your finger at the top section on the Face ID system area during the phone call. If the display goes off and comes back on when you remove your hand, the proximity sensor is perfectly working fine.
The next important setting change you need to do is enable the tap to wake function. This feature is available in iPhone 10 and above models, allowing you to simply tap on the screen once to turn on the display.
Lastly, you can try removing any tempered glass or screen protectors that could result in poor proximity sensor performance. If the problem persists after trying all the previous troubleshooting steps, you can visit the Apple service center for hardware diagnosis and performing an iOS restore.
In conclusion, we hope these tips helped you resolve the problem of your iPhone screen or display not turning on during a phone call. Don’t forget to try these troubleshooting steps one by one and remove any screen protectors that may affect your iPhone’s performance.
