You put your iPhone 13 to your ear when you receive a call and bam, the iPhone 13 goes black during the call for the rest of the call. What gives? How to resolve this iPhone going black during call issue? Here is how to fix the iPhone 13 that goes black during the call and what to do if iPhone goes black and the screen becomes unresponsive during the call.

Part I: Reasons Why iPhone 13 Screen Goes Black During Calls

The first time it happens, it might come as a surprise that the iPhone 13 goes black during call. Even more surprising could be that it never comes back to life until the call is over! Why does that happen? Here are some reasons why the iPhone 13 goes black during the call.

Reason 1: Proximity Sensor

Your iPhone 13 features a proximity sensor that is designed to shut the screen off when it detects the iPhone to be in close proximity to your ear. This is so that your face does not accidentally trigger a touch response on the screen, although the iPhone is very well configured to not register accidental touches, and also to save battery life since you would not be using the screen anyway when talking with the screen to your ear.

Reason 2: Dirt Around Proximity Sensor

If your iPhone 13 goes black during call and does not come back to life easily even if you take it off your ear, then it is possible that the sensor is dirty and is not able to operate properly. You cannot clean the sensor since it is hidden behind glass, but this only means that you can clean the screen so that the sensor can 'see' clearly and operate efficiently. If there is dirt on the screen, or if the screen is, say, smeared with something that makes a film on top of the sensor, it is likely to not operate efficiently and reliably.

Reason 3: Faulty Proximity Sensor

If you find that the iPhone does not come to life even if you take the iPhone off your ear, then there is a chance that the sensor is faulty. If the iPhone is in warranty, as your new iPhone 13 is going to be, then it is best to take the iPhone to a service center.

Part II: How to Fix iPhone 13 Screen Goes Black During Calls

Fortunately, proximity sensors do not really develop faults that way for the life of your device, and there are a few things you can do to see if that helps the issue before you figure that the sensor might have developed a fault and you need to take it to a service center.

Tip 1: Restart The iPhone 13

For most issues on iPhone, a restart usually fixes things on its own. If you are facing issues with iPhone 13 going black while calling or even after calling, a restart is one of the first things you should attempt. Here's how to restart iPhone 13:

Step 1: Press and hold the Volume Up key and Side Button together until the slider appears

Step 2: Drag the slider to turn the iPhone off

Step 3: After a few seconds, turn the iPhone back on using the Side Button.

Tip 2: Clean The Proximity Sensor

Cleaning the screen is the only way to 'clean' the proximity sensor. If there is any film developed on the screen that you may or may not be able to see but is interfering with the proper operation of the proximity sensor, this is going to cause issues such as iPhone 13 going black all of a sudden. That's because the proximity sensor erringly registered the presence of your ear when it was just the film development on the screen. Here's how to clean the gunk from your iPhone 13 screen:

Step 1: Take a soft cotton swab

Step 2: Take some isopropyl alcohol

Step 3: Dab and moisten the swab in the alcohol

Step 4: Gently, in circular motion, clear your iPhone 13 screen.

Do not use any detergent or other abrasive chemicals on your iPhone. Isopropyl alcohol is the same liquid that you use to clean and sanitize a wound. It is gentle and non-reactive.

Tip 3: Use The Power Button to Wake iPhone

It is possible that the iPhone screen might not wake during call if you press the volume buttons. The better way to bring the iPhone screen to wake up when iPhone went black after the phone call is to press the Side Button to power the device.

Tip 4: Remove iPhone From Case

If you are using a knock-off case, it is possible that the case lip might be interfering with the iPhone 13's sensors. Remove the iPhone from its case and see if that resolves the issue.

Tip 5: Remove Screen Protector

If you are using a screen protector on your device, remove it, even if there is a cutout for the sensors. At this juncture, you want to eliminate all possible reasons. Although, most likely, this is the reason - some screen protectors, especially for iPhone 13, do not feature a cutout for the sensors since the earpiece on the iPhone 13 has been pushed up to align with the edge of the chassis, allowing protectors to not require any cutouts. Remove any screen protector and check if that resolves the iPhone 13 goes black during call issue.

Tip 6: Reset All Settings

Sometimes, issues can be helped with resetting all settings. To reset all settings on your iPhone:

Step 1: Launch Settings and tap General

Step 2: Scroll down and tap Transfer Or Reset iPhone

Step 4: Tap Reset All Settings

Step 5: Punch in your passcode and let the iPhone reset all your settings.

Tip 7: Erase All Settings and Reset iPhone

If the above did not work, the other option is to erase all settings on iPhone and reset the iPhone altogether. Doing this will require a little planning at your end since this will delete all your data from the iPhone. App data that exists in iCloud will not be deleted, but data in some apps such as, for example, if you have downloaded some movies to watch in VLC, those will be deleted if they are on your iPhone.

Before resetting the iPhone entirely, it is advised to backup all data. You can do this with iTunes or macOS Finder, or you can also use third-party tools such as Dr.Fone - Phone Backup (iOS) to back up your iPhone easily and intuitively, in a beautiful software interface. What's more, it allows you to do something that you cannot do if you use iTunes or macOS Finder - selective backup. Using Dr.Fone - Phone Backup (iOS), you can choose what to back up easily, thereby getting more control on your data.

Conclusion

It is annoying when you want to interact with your iPhone during a call and the iPhone screen goes black during call, totally unresponsive to touch. Such an issue can be either a software bug or an issue with a screen protector or a case or could be that the screen is dirty, or it could be that the proximity sensor itself is faulty and needs repair. It could also be a firmware corruption that could be fixed by restoring iOS again. Before you visit an Apple Store, you might want to try all the methods listed to save yourself an unnecessary trip. Note that resetting all settings and erasing the iPhone will wipe your data from the iPhone, so backup your data first either through iTunes and macOS Finder or through third-party tools such as Dr.Fone - Phone Backup (iOS) that let you choose what to backup, giving you granular control over your backups. Then, you can use the same Dr.Fone suite and choose the System Repair module to fix your iPhone 13 screen going black and unresponsive issue completely.
