Troubleshooting a problem on your iPhone 7 incoming call delay after iOS 13 update

Adverse symptoms that are suddenly transpiring after a major system transition are usually due to some minor flaws on either apps or system functions. To eliminate all possible triggers, perform each of the following solutions, then place a test call afterwards to find out which of them is able to fix the problem. Note that this would be a trial-and-error procedure since the underlying cause is yet to be determined.

Before you begin, check your network signal status on the phone and make sure the signal is stable. If it shows an unstable signal bars, then signal issue could be the root cause and therefore must be resolved firsthand or contact your network service provider to find out whether or not a temporary outage is transpiring. If there’s no problem with the network signal and yet you’re still troubled with incoming call delay on your iPhone 7 iOS 13, then you can go ahead and start troubleshooting.


First solution: Quit the Phone app then restart your iPhone.

Like any other apps, stock applications including the Phone app can also succumb to some random flaws following a major system transition. When this happens, different types of errors could occur while using the application. To make sure this isn’t causing incoming call delay on your iPhone 7 in iOS 13, follow these steps to force close the Phone app on your iPhone 7:

  1. Double-press the Home button to pull up the Apps Switcher or Multitasking screen. This screen contains the previews/cards of all applications you’ve recently used and left running in the background.
  2. Tap and drag the Phone app card/preview to the top-corner of the screen to close or end individual applications.

Follow the same steps to end all other background apps to prevent them from causing conflicts with any app you’re using on your device. Just follow these steps to proceed with a soft reset on your iPhone 7:

  1. Press and hold down the Side (Power) button for a few seconds until the Slide To Power Off appears.
  2. Drag the slider to the right to power off your device completely.
  3. After 30 seconds, press and hold down the Side (Power) button again until the Apple logo appears.

When your iPhone is finished rebooting, wait for it to re-establish network signal and once the signal has stabilized, use another phone to place a test call to your iPhone 7 and see if the incoming call notification alert is still delayed or not anymore.

Second solution: Disconnect all Bluetooth devices.

If you’ve got any saved Bluetooth-enabled devices that your iPhone was previously paired with, a system glitch could trigger your phone to automatically connect to any of these Bluetooth devices (intermittently) and thereby results in an unstable audio output rendering. To eliminate this from the possible culprits, disable Bluetooth on your iPhone 7, then try placing a test call.

  • You can disable it through Settings-> Bluetooth menu and then toggle the switch to turn the feature off.

Alternatively, you can toggle the Bluetooth icon from the control center to disable Bluetooth on your iPhone 7. 

If Do Not Disturb feature is enabled on your phone, try to disable it too and then place a test call to see if the problem is gone. When enabled, DND can also stop or delay incoming call notification alerts on your device.

In iOS 13, you can disable Do Not Disturb through these steps:

  1. Open the Control Center by swiping up from the Home button on your iPhone 7.
  2. Then long press  (use a 3D touch) on the DND (crescent moon) icon on the control center to turn the feature on or off.

You can also access and manage Do Not Disturb through Settings-> Do Not Disturb menu and then toggle the switch next to Do Not Disturb to disable it.


Third solution: Utilize the Airplane Mode toggle to fix your iPhone problem on incoming call delay after iOS 13 update.

Another old trick that’s been proven to work wonders when it comes to resolving wireless connectivity issues including those affecting an iPhone’s calling functions is the so-called Airplane mode trick. And here’s how it works:

  1. Tap Settings from your Home screen.
  2. Select Airplane Mode.
  3. Toggle the switch to turn Airplane mode on. This disables your iPhone’s wireless radios and relevant functions.
  4. While Airplane mode is enabled, restart your iPhone.
  5. After it reboots, go back to Settings-> Airplane Mode menu then toggle the switch to turn Airplane Mode off again.

Performing this trick is like giving an instant refresh to wireless features of your iPhone and thereby eliminates random flaws. Just don’t forget to re-enable, Wi-Fi, cellular data and other wireless functions afterwards so you can use them again on your device.

Fourth solution: Reset network settings on your iPhone.

Network-related issues including those affecting incoming calls can also be remedied by a network reset. This is usually needed if the recent update happened to ruined your phone’s network configurations. Performing this reset does not affect any saved information but will delete all network settings, saved Wi-Fi networks and Bluetooth connections. 

  1. From your Home screen, tap Settings.
  2. Select General.
  3. Scroll down to and tap on Reset.
  4. Select the option to Reset network settings.
  5. Enter your device passcode when asked to proceed.
  6. Then tap the option to confirm that you’d want to reset network settings on your phone.

After the reset, your phone restarts on its own and then loads up the default network values and options. To get back online, you’ll need to re-enable cellular data or reconnect to your Wi-Fi network.


Fifth solution: Use iTunes to restore your iPhone to its factory defaults.

Resorting to a full system reset is also another option if the previous reset doesn’t solve the problem. This should eliminate complex system errors that might have ruined the normal incoming call system of your phone. But before you continue, be sure to back up all critical data stored on your iPhone to your iCloud account or to iTunes. Once you’re all set, follow these steps to start wiping and restoring your iPhone in iTunes:

  1. Open iTunes on your computer, if you haven’t already.
  2. Connect your iPhone to the computer with the USB cable or Lightning cable that came with it.
  3. Wait for iTunes to recognize your device and when it does, you should see your iPhone’s icon in iTunes.
  4. Click to select your iPhone 7 when it appears in iTunes.
  5. Then navigate to the Summary section.
  6. Click on the Restore [iPhone] button.
  7. If prompted, click on the Restore button again to confirm.

This should prompt iTunes to start erasing your device and then installs the latest version of operating system available. As soon as your iPhone is done resetting and restoring its factory default settings, you can use the start-up wizard to proceed with the initial setup.

Is your iPhone 7 still facing the same problem on incoming call delay after iOS 13 update?

Escalate the problem to your service provider/carrier if all the above solutions failed to fix it. Doing so will help eliminate network and account-related factors from the underlying causes. If necessary, your carrier will determine whether or not to push a new carrier update to offer permanent solution. You can also report the problem to Apple Support. Considering that the symptom had instigated from the recent update makes it very possible that an iOS bug is the trigger and therefore needs to be addressed.
