Possible causes of Bluetooth problems on your iPhone 7

First, and one of the common reasons as to why many people are having trouble pairing with or connecting their iPhone to Bluetooth is because the feature is not enabled on either device in the first place. To make sure this is not what’s causing you the same trouble, verify and ensure that Bluetooth is turned on in your iPhone settings. Second possible reason is that the Bluetooth device you are trying to connect to is probably out of range or your iPhone is just way too far from it. Unlike Wi-Fi devices that can connect from anywhere as long as they’re connected to the Internet, Bluetooth devices are only able to communicate with each other on proximity. Typically, Bluetooth range is approximately 20 to 30 feet. To make sure this is not the case, try to pair your devices when they are right next to each other and then see how they do.

There are also some instances when the problem is isolated to a Bluetooth device. Just like if your iPhone 7 can connect to other Bluetooth devices except for a particular device. This denotes that the problem is not your iPhone.

Bluetooth problems can also arise due to random software malfunctions or apps glitches especially when using relevant apps or contents that get corrupted. Faulty updates can also cause the same problem on your iPhone’s Bluetooth connectivity.

Another possibility is that the Bluetooth accessory is not compatible with your iPhone 7 or does not support your iOS device.

In worst case scenario, the problem could be due to a faulty hardware like when relevant components on your iPhone has physical or liquid damage. Your iPhone is designed with an antenna that gives it Bluetooth functionality and when this component gets damaged from a drop or liquid exposure, that’s when problems instigate. If you’re having problems with both Bluetooth and Wi-Fi functions on your iPhone and that there were previous instances when the iPhone was dropped or got wet, then most likely it’s a hardware issue.

Potential Solutions and Workarounds to deal with your iPhone 7 that won’t connect to Bluetooth

Try the following workarounds to figure out why your iPhone 7 won’t connect to Bluetooth and at the same time resolve the underlying cause. Be sure to test your device after performing each step to see the result.

First solution: Reboot your iPhone 7 and other Bluetooth devices.

Rebooting often resolves minor problems that are triggered by software glitches. It’s a simple yet most effective solution you can try on first. If you don’t see positive result after the first reboot, try to do it twice up to five times. So here’s what you should do:

  1. Press and hold the Sleep/Wake button to power off your iPhone.
  2. When the Slide To Power Off appears on the screen, swipe the power icon from left to right to turn off your device.
  3. Wait for about 30 seconds and then turn your iPhone back on by pressing and holding the Sleep/Wake button again until the Apple logo appears on the display.

After rebooting your iPhone, restart your other Bluetooth device and then try pairing them again to see if that has fixed the problem.

Second solution: Toggle Bluetooth switch off and then back on.

This workaround has done good things to some people who were having some troubles connecting their iPhone to other Bluetooth devices at first. Often times in this case, the problem was triggered by minor software glitches that might have prevented the iPhone and Bluetooth device from pairing. Should you wish to try this workaround, here are your options.

Turn Bluetooth off through your iPhone Settings with these steps:

  1. Navigate to the Home screen.
  2. Tap Settings to open the Settings app.
  3. Tap the switch next to Bluetooth. The switch appears gray when Bluetooth is off.
  4. Tap the Bluetooth switch again to turn it back on. You will know if it’s on when the switch turns green.

Alternatively, you can turn Bluetooth on or off through the Control Center. Here’s how:

  1. Swipe up from the bottom of your iPhone screen. Doing so opens the Control Center.
  2. Tap the Bluetooth icon (looks like B). You will know if Bluetooth is disabled or turned off when the icon appears black inside a gray circle.
  3. Tap the Bluetooth icon again to turn it back on. You will know if Bluetooth is on when the B icon appears white inside a blue circle.

You can also turn Bluetooth off and on using Siri. Here’s how:

  1. Press and hold the Home button or say “Hey Siri” to turn on Siri.
  2. Say “Turn off Bluetooth” to turn Bluetooth off.
  3. Say “Turn on Bluetooth” to turn Bluetooth back on.

After turning Bluetooth off and on, try pairing your iPhone 7 and Bluetooth devices again to see if it is already working.

Third solution: Switch pairing mode on or off on your Bluetooth device.

Most Bluetooth devices have a switch or button that is used to turn Bluetooth pairing mode on or off. Locate that button or switch on your Bluetooth device and then press it to take it out of Bluetooth pairing mode.Wait about 30 seconds and then press that button or switch again to put the device back into pairing mode. Try connecting your iPhone 7 to your Bluetooth device again after doing so. Some devices will automatically enable Bluetooth functionality when turned on.

Fourth solution: Unpair or forget your Bluetooth device.

Unpairing or forgetting your Bluetooth device, putting it back in discovery mode, then pair and connect it again, often fix the problem especially if the Bluetooth function is messed up with some corrupted contents or applications. Doing so will consider the other device was never connected to your iPhone 7, thus giving both devices a fresh start when paired. Follow these steps to forget a Bluetooth device on your iPhone 7:

  1. Navigate to the Home screen and tap Settings.
  2. Tap Bluetooth.
  3. Continue by tapping the blue “i” 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.

You will known if the device has been forgotten when it no longer appears under My Devices on your iPhone Settings-> Bluetooth menu.

After forgetting the Bluetooth device, reboot your iPhone and then try to pair both devices again. Make sure that your Bluetooth device is in pairing mode and then perform these steps:

  1. On your iPhone, go to Settings-> Bluetooth.
  2. Toggle the Bluetooth switch to turn the feature on, if necessary.
  3. Place your Bluetooth device in discovery mode and wait for it to appear on your iPhone 7.
  4. Tap to select your Bluetooth device to pair. You may need to enter the PIN or passcode.
  5. Wait until pairing is complete.

If your Bluetooth device pairs to your iPhone and starts working again, then you’re good. Otherwise, try other applicable solutions.

Fifth solution: Reset network settings on your iPhone 7.

Sometimes Bluetooth problems occur due to network connectivity issues caused by misconfigured or incorrect network settings on the iPhone and resetting the network settings often gets the problem fixed. Doing so will erase the data on your iPhone from all of your Bluetooth accessories, Wi-Fi network and VPN settings. As a result, your iPhone will have a fresh start when connecting to Bluetooth devices or wireless networks.

Before you give this a try, be sure to take note of all your Wi-Fi passwords because you will need to re-enter them afterwards to configure wireless network on your iPhone again. Once you got them noted, follow these steps:

  1. Tap Settings on the Home screen.
  2. Tap General.
  3. Scroll to and tap Reset.
  4. Select Reset Network Settings.
  5. Enter your passcode, if prompted.
  6. Wait until your iPhone reset the network settings and reboots.

After the reboot, your network settings have been reset. You may then try pairing your Bluetooth device with your iPhone again. You will be pairing the devices as if they are being connected for the first time because all the Bluetooth device data on your iPhone was erased in the network settings reset process.

Sixth solution: Restore your iPhone 7.

Your last option and potential solution if the problem persists and your iPhone 7 still won’t connect to your Bluetooth device after performing all other applicable workarounds would be a system restore. You can go for the usual restore through iTunes or perform a DFU mode restore instead. Be sure to backup your iPhone before performing a system restore for safekeeping.

To restore your iPhone through iTunes the usual way, you will need a computer with the latest version of iTunes installed. When everything is set, follow these steps:

  1. Open iTunes on the computer.
  2. Connect your iPhone to the computer using the supplied USB cable/connector.
  3. Wait until iTunes to recognize your iPhone 7 or tap the option to Trust This Computer to proceed.
  4. Select your iPhone 7 from the list of available devices in iTunes.
  5. Click the Restore button.
  6. If prompted, select the previous iOS file you want to use.

Wait until the restore process is complete.

Should you wish to go for a most in-depth type of iOS restore, you can go for a DFU mode restore instead. It is possible that the problem is caused by a more serious software glitch which could not be rectified by any of the previous methods but a DFU mode can.

DFU mode restore is the deepest type of iPhone restore usually performed by Apple technicians to fix complex software issues. However, a DFU restore is not recommended if your iPhone has physical or liquid damage. Because doing so will cause your iPhone to brick and become completely dysfunctional since the DFU mode restore couldn’t complete due to hardware damage. If you are certain that your iPhone has no damage to any of its hardware component and that you’re decided to give it a try, then here’s how it’s done:


  1. Plug your iPhone into your computer and open iTunes. It doesn’t matter if your iPhone is on or off.
  2. Press and hold the Sleep / Wake button and the Volume down button together for 8 seconds.
  3. After 8 seconds, release the Sleep / Wake Button but continue to hold the Volume Down button until iTunes says “iTunes has detected an iPhone in recovery mode.”
  4. Let go of the Volume Down button.
  5. Your iPhone’s screen will be completely black if you’ve successfully entered DFU mode. If it’s not, try again from the beginning.
  6. Restore your iPhone 7 using iTunes.


If iOS restores won’t work either, then you should already consider escalating the problem to your device carrier or Apple Support for further assistance and other recommendations. You should contact Apple Support if you cannot turn on Bluetooth on your iPhone because the setting is grayed out, your iPhone 7 cannot connect to any Bluetooth accessories, or when you have confirmed that your Bluetooth device is working properly.
