First solution: Restart your iPhone 7 Plus and Bluetooth device.

Minor software glitches are likely triggered when implementing new updates. And to make things go back to normal, you need to manually trigger your device to restart. This process is referred to as a soft reset. Aside from rectifying minor system errors, it also helps refresh your device system. So if you haven’t already, give it a try with these steps:

  1. Press and hold the Power button until the Power off slider appears.
  2. Drag the slider to turn your iPhone completely off.
  3. After about 30 seconds, press and hold the Power button again until you see the Apple logo.
  4. Alternatively, you can shut your phone down by going to Settings-> General-> Shut Down menu, and then select the option to turn off your iPhone.

No data will be deleted in the process so backing up files won’t be necessary.

  • On your Bluetooth device, locate the Power switch then press on that until the device powers down. After 30 seconds, press the Power switch until it turns on again.

Retry Bluetooth pairing when both devices have restarted.

Second solution: Turn Bluetooth off and on again.

Turning Bluetooth off and on can help refresh Bluetooth connections on your iPhone. The new update might have caused your iPhone’s Bluetooth functions to become a bit unstable and therefore needs to be restarted. So here’s what you should do then:

  1. Tap Settings from the Home screen.
  2. Tap Bluetooth.
  3. Tap the Bluetooth switch to turn the feature off for a few seconds.
  4. Then tap the switch again to turn Bluetooth on.

Alternatively, you can try turning Airplane mode on for a few seconds and then turn it off again.

Try pairing your iPhone and Bluetooth device afterwards and see if everything is working fine now.

Third solution: Delete/forget saved Bluetooth devices on your iPhone 7 Plus.

Deleting or forgetting Bluetooth removes your Bluetooth device from your phone system so the next time you pair or connect, it’s like the first time for your iPhone to pair or connect to your Bluetooth device. This can also help eliminate any corrupted Bluetooth connections saved on  your phone. So here’s what you should do:

  1. From the Home screen, tap Settings.
  2. Then tap Bluetooth.
  3. Make sure Bluetooth is enabled to view the list of Bluetooth devices.
  4. Tap the information (i) icon next to the Bluetooth device you want to delete or forget.
  5. Then tap Forget This Device.
  6. If prompted, tap Forget Device again to confirm.

If you see other Bluetooth devices saved on your phone, then remove or forget them as well to prevent any of them from causing conflict.

  • If it is a car Bluetooth that you’re having trouble pairing with your iPhone 7 Plus after the update, navigate to your iPhone Settings-> Bluetooth-> Other Devices, then look for the name of your car Bluetooth. Tap on it to Forget or remove pairing.

You will know if the Bluetooth device is already forgotten if it no longer shows under My Devices in Settings-> Bluetooth menu.

Try that and see if Bluetooth pairing works as intended.

Fourth solution: Reset all settings and network settings on your iPhone 7 Plus.

Some updates automatically override or alter your device settings and so it’s possible that your Bluetooth settings are affected. To make sure this isn’t the root cause, you can just reset all settings on your iPhone and re-configure them afterwards. Here’s how to reset all settings on your iPhone 7 Plus:

  1. Tap Settings from the Home screen.
  2. Tap General.
  3. Scroll to and tap Reset.
  4. Select the option to Reset all settings to erase all settings and restore the original or default configurations without affecting your iPhone data.
  5. You can also tap the option to Reset network settings to reset all your current network configurations and restore them to defaults.
  6. If prompted, enter your device passcode then confirm reset.

Your iPhone restarts automatically when the reset is finished. By then you can re-configure your settings and re-enable Wi-Fi and Bluetooth manually.

Fifth solution: Reset your iPhone 7 Plus (factory reset).

You may have to reset everything back to defaults if the problem continues after exhausting all possible solutions. What you’re dealing with could be a complex system issue especially if the new update contains contains some tough bugs. But before you do so, be sure to back up all your important data as they will be erased in the process. Once the backup is secured, follow these steps to reset your iPhone 7 Plus to factory defaults through settings menu:

  3. Scroll to and tap Reset.
  4. Select the option to Erase all content and settings. This will trigger your device to begin wiping everything from the  system including your downloaded contents, apps, and personal data. Bugs and other glitches will be deleted too.

When the reset is finished, your iPhone restarts and then loads everything in factory defaults. By then you can proceed with the initial setup process, enable Wi-Fi, Bluetooth, and other features you need. Then retry pairing or connecting your iPhone 7 Plus to your Bluetooth device.

Alternatively, you can use iTunes to reset your iPhone to factory defaults or restore from a previous iOS backup either via recovery mode or DFU mode restore.
