Bluetooth Not Working On iPhone 8 Plus? The Fix!

David Lynch

SEPTEMBER 25, 2017

Your iPhone 8 Plus won't connect to Bluetooth and you're not sure why. Bluetooth makes it possible to connect wirelessly to other Bluetooth-enabled devices such as AirPods, headphones, speakers, and more. This article will explain how to fix the problem when Bluetooth is not working on your iPhone 8 Plus!

Before You Can Pair Your iPhone To Bluetooth Devices

Your iPhone 8 Plus can only connect to other Bluetooth devices when Bluetooth is turned on. Go to Settings -> Bluetooth and turn on the switch next to Bluetooth at the top of the menu.

Your iPhone also needs to be "in range" of your Bluetooth device before they can connect. "In range" typically means about 25 feet — if your devices are further apart than that, they may not pair!

Try Pairing Your iPhone To A Different Bluetooth Device

When you have trouble connecting your iPhone to a Bluetooth device, you can diagnose whether the problem is coming from your iPhone or the Bluetooth device by attempting to pair your iPhone with a different Bluetooth device. If your iPhone connects to one device but not the other, then you've identified that the connectivity issue is being caused by the particular Bluetooth device, not your iPhone.

How Do I Try Pairing My iPhone To A Different Bluetooth Device?

  1. To pair your iPhone to a different Bluetooth device, make sure your iPhone has Bluetooth turned on and your Bluetooth device is in pairing mode.
  2. Open the Settings app on your iPhone.
  3. Tap Bluetooth.
  4. Under My Devices, tap the Bluetooth device you want to connect to.
  5. If the Bluetooth device and your iPhone paired properly, your original connectivity issue was being caused by the other Bluetooth device.

Forget The Bluetooth Device

When your iPhone forgets a Bluetooth device, it will be as if the two devices were never connected. Next time you pair the Bluetooth with your iPhone, it will be like pairing the devices for the first time, giving the connection a fresh start.

  1. Open the Settings app.
  2. Tap Bluetooth.
  3. Tap on the blue "i" next to the Bluetooth device you want to forget.

  6. You'll know the device has been forgotten when it doesn't appear under Devices in Bluetooth.

Reset Network Settings

When your iPhone connects to a Wi-Fi or Bluetooth device for the first time, it saves information about how to connect to that network or device. If something changes with that process, it may cause connectivity issues.

Deep software problems, especially with network settings, can be difficult to track down. Rather than trying to track an issue down, we're going to reset all network settings and give your iPhone a fresh start.

How Do I Reset Network Settings?

  1. Open the Settings app.
  2. Tap General.
  3. Scroll down and tap Transfer Or Reset iPhone.
  4. Tap Reset.
  5. Tap Reset Network Settings.
  6. Enter your passcode if prompted.
  7. Your iPhone will shut down, reset, and turn itself on again when the reset is complete.

DFU Restore Your iPhone

A DFU restore has the potential to fix software problems by completely erasing the code which may be causing your problem. The code is rewritten as if your iPhone is brand new, so the software problem may get solved.

Think of it like a house that has cracks in the foundation. Rather than try and fix the cracks, we are building an entirely new foundation.

If you can, back up your iPhone before completing a DFU restore. Any time you do a restore, it erases everything from your iPhone. However, after the restore is completed, you restore all your backed up data back onto your iPhone.

Repair Your iPhone With Apple

Apple repairs iPhones at the Genius Bar in Apple Stores and through their online mail-in repair service. Apple repairs are high-quality, but out-of-warranty repairs can be much more expensive than third-party solutions. If you're looking to save some money you're not covered by Apple's warranty, you may want to check out our other recommendations.

How Do I Repair My iPhone With Apple?

How To Repair Your iPhone With Apple's Mail-In Service

  1. Visit Apple's support website to begin the online mail-in repair process.
  2. Alternatively, call 1-800-MY-APPLE (1-800-692-7753) to set up a repair.

How To Repair Your iPhone At The Genius Bar Inside Your Local Apple Store

  1. Visit Apple's website to make a Genius Bar appointment before you go into the store. Apple Stores are extremely busy, and if you don't have an appointment, you may have to wait for hours or end up being turned away. (Editor's note: I'm a former Apple tech and we're not exaggerating — please, do yourself a favor and make an appointment first!)
  2. When you arrive, go to the Genius Bar to check in for your appointment.
  3. Genius Bar appointments always include free diagnosis. If you're under warranty, many repairs can be done on the spot, but it all depends upon which parts are in stock. If you're not under warranty, the Genius will give you a quote for the cost of a repair.

I am able to connect my iPhone 8+ to my uconnect in car but messaging is not working through my uconnect. It worked fine with my iPhone 6. Is there a way to turn this functionality on?
