If not, follow these methods below to rule out software-related issues on your iPhone XS Max that may prevent it from setting up a secure Bluetooth connection.

Solution 1: Restart your iPhone XS Max

If you haven’t already restarted your phone after the update, there is a chance that some of the apps or system functions are misbehaving. This is very normal after a system update. To halt adverse symptoms, you should restart your iPhone XS Max to clear junk files from the memory as well as refresh apps and system functions. Here’s how to get it done:

  1. Press and hold the Power button and one of the Volume buttons simultaneously for a few seconds.

  3. After 1 minute, press and hold the Power button again until it reboots.

This process will not affect any saved data, so it won’t cause permanent data loss.

Solution 2: Toggle Bluetooth OFF and ON again.

It should also be important to refresh your Bluetooth connection as the update might have ruined it. To do so, you can disable Bluetooth for a few seconds and re-enable it. You can also try the Airplane Mode trick to restart wireless functions. Start with the Bluetooth restart by following these steps:

  1. Head to Settings-> Bluetooth menu.
  2. Toggle the Bluetooth switch OFF.
  3. After 10 seconds, tap on the switch to enable Bluetooth back on.
  4. Wait for the Bluetooth device to appear in the list of available Bluetooth devices and then choose it to start pairing.

If it doesn’t work, you can try the Airplane Mode trick next. To do so:

  1. Navigate to Settings-> Airplane Mode menu.
  2. Toggle the switch to enable Airplane Mode. This will also disable the wireless radios like Wi-Fi and Bluetooth connections.
  3. Once Airplane Mode is turned on, restart your iPhone XS Max.
  4. Next, return to Settings -> Airplane Mode menu and disable Airplane Mode again to re-enable wireless functions.

After disabling Airplane mode, you should then enable Bluetooth connection and then retry pairing your phone with other Bluetooth devices. After that, check if it’s working already. If not, move on to the next methods.

Solution 3: Forget Bluetooth connection on your phone.

The existing Bluetooth connections can be affected due to an update bug. When it occurs, adverse symptoms could happen from random Bluetooth errors. You need to unpair your phone from Bluetooth devices to fix it. To delete pairing, you can use the Forget Bluetooth option on your iPhone XS Max:

  1. Tap on Settings from the Home screen.
  2. Choose Bluetooth and enable Wi-Fi.
  3. Select the Bluetooth device you want to forget.
  4. Tap on the “i” icon next to the name of the Bluetooth device.
  5. Select Forget this Device option

Solution 5: Restore your iPhone XS Max using iTunes.

The last option to fix tough system bugs is restoring your iPhone through iTunes. However, it’s only possible if you have already had a previous backup on your computer before updating. You can restore from the backup until Apple releases a fix patch to resolve the recent update bug. To restore your iPhone in iTunes through recovery mode:

  2. Once it’s connected, quickly press and release the Volume Up button.
  3. Do the same with the Volume Down button.
  4. Press and hold the Power button and continue holding as it restarts. Don’t release the Power button when you see the Apple logo since you need to boot it into the recovery state.
  5. Release the  Power button when the Connect to iTunes logo shows up on the screen.
  6. On iTunes software, you will see a message saying that your connected iPhone is now in recovery mode and you will be prompted to update or restore.
  7. Click on Restore option to erase everything from your iPhone system and then restore the firmware through iTunes.

The process could take 15 minutes to be done. You will need to wait for iTunes to complete downloading the latest software and then complete the system restore. Simply follow the onscreen prompts in iTunes.
