How to troubleshoot iPhone 8 that won’t pair with Bluetooth devices

Before you troubleshoot, make sure both your iPhone and Bluetooth device are within range. Unlike Wi-Fi, Bluetooth connectivity is based on proximity between 30 feet to 100 feet (new Bluetooth versions). Also make sure that your Bluetooth device is turned on and in discoverable mode. The Bluetooth device must also be compatible with your iPhone 8 and the iOS platform. Most importantly, verify and ensure that Bluetooth is enabled on your iPhone. If you’ve got all the requisites checked and yet your iPhone 8 still won’t pair or connect to your Bluetooth device, try these methods.

First solution: Soft reset/restart your iPhone 8.

If you haven’t restarted your iPhone after the iOS update installation, there is a chance that some functions including Bluetooth are glitching. Should this be a minor software glitch following an update, a soft reset is usually enough to fix it. That said, reboot your iPhone 8 with these steps:

  1. Press and hold the Side/Power button until the Slide to Power Off command appears.
  2. Drag the slider to the right to turn your iPhone completely off.
  3. After 30 seconds, press and hold the Power button until the Apple logo appears and then release.

You don’t need to back up files beforehand because a soft reset/restart doesn’t affect internal data stored on the phone memory.

Second solution: Reboot the Bluetooth device.

It may not be enough to restart your iPhone only as it’s also likely that the Bluetooth device is experiencing minor software malfunctions. To clear this out, reboot your Bluetooth device as well. To do this, simply find the Power button on your Bluetooth device then press on it until it powers off. After 30 seconds, press that button again until the device turns on. Doing so clears any minor firmware errors that may have prevented the device from communicating with your iPhone.

Third solution: Turn Bluetooth off and then back on.

Another simple solution to minor errors affecting Bluetooth function of your phone is by turning Bluetooth off and then on again. It’s another way to refresh the Bluetooth system and clears any erratic caches that may have spoiled the supposed to be simple pairing process. There are different ways to turn Bluetooth on and off your iPhone but the usual procedure is through the settings menu. Here’s how it’s done:

  1. Tap Settings from the Home screen.
  2. Tap Bluetooth.
  3. Then tap the switch next to Bluetooth. You will know when it’s off if the switch is gray.
  4. After a few seconds, tap the switch again to turn Bluetooth back on.

The Bluetooth switch then turns green, which means Bluetooth is enabled and that your iPhone is all set for pairing again.

Fourth solution: Forget Bluetooth device on your iPhone 8.

The new platform transition may have caused some of your iPhone’s Bluetooth information to become corrupted and thus the feature isn’t working as intended. A possible solution to this would be to forget or delete the Bluetooth device from your iPhone’s memory and then set it up again. Here’s how:

  1. Tap Settings from the Home screen.
  2. Tap Bluetooth.
  3. Tap the blue “i” or information icon next to the Bluetooth device you want to forget.
  4. Tap the option to Forget this Device.
  5. If prompted, tap Forget Device to confirm.

The device will then be erased from the Bluetooth list.

  • To check if the device has been successfully forgotten, go to Settings-> Bluetooth-> My Devices menu. It shouldn’t show up in there.

After forgetting your Bluetooth device, reboot your iPhone to dump errant cached files. Once your iPhone has rebooted, enable the feature, keep your Bluetooth device near your iPhone and then start pairing them again. At this point, your devices will attempt to pair as if it’s the first time they do.

Fifth solution: Reset network settings on your iPhone 8.

If your iPhone 8 still won’t pair or connect to your Bluetooth device up to this point, you may now consider performing software resets. First you can try a network settings reset to clear any possible network errors inflicted by the new iOS update, which may have eventually troubled the iPhone’s Bluetooth functions. To reset network settings on your iPhone 8, follow these steps:

  1. Tap Settings from the Home screen.
  2. Tap General.
  3. Scroll to and tap Reset.
  4. Select Reset Network Settings from the given options.
  5. If prompted, enter your passcode to continue.
  6. Then tap the option to confirm network settings reset.

Your device will then instigate the network settings reset and when it’s done, it’ll restart automatically. After the restart, you will need to set up your network connections, enable Bluetooth, then re-attempt pairing your iPhone 8 with your Bluetooth accessory. If the pairing is successful, then your problem is solved. Otherwise, you can take chances from a master reset or iOS restore through iTunes.

Before you proceed with an iOS reset or restore though, you can try pairing your iPhone 8 with other compatible Bluetooth devices you have. If it successfully pairs with your other Bluetooth devices, then obviously the problem is on the previous Bluetooth device you’re trying to pair with. In that case, you may attempt to consult the device manufacturer for other recommendations.

Other options

Aside from a network settings reset, there are also other software resets you can try, if your iPhone 8 still won’t pair with or connect to your Bluetooth device. Should the problem is inflicted by more complicated system errors, then you can try a factory reset or master reset. Or you can also carry out an iOS restore via recovery mode or DFU mode, if necessary. To perform an iOS restore, you will need to use a computer with the latest version of iTunes software installed. Both factory reset and iOS restore result to data loss, hence creating a backup is necessary beforehand. You may opt to restore your iPhone 8 to previous iOS backup or downgrade iOS in DFU mode. While downgrading iOS is discouraged, it may be your last best hope. If resetting and restoring iOS aren’t you’re preferred solutions, then you can just take your iPhone to the nearest Apple store and have it diagnosed by an Apple technician instead.
