Common Bluetooth Issues After Updating to iOS 12
Please note that the Bluetooth iCon has been removed in iOS 12. This is the familiar icon that used to be located at top of your screen in iOS 11 versions. This is not a bug but a feature change in iOS 12.
Most of the symptoms reported center around the following issues:
- After updating the iPhone to iOS 12, the iPhone is unable to discover the third party Bluetooth device
- When connecting to the Bluetooth device, it merely spins forever while attempting to connect and doesn’t resolve
- A crackling voice on the speaker or headset of the Bluetooth device after updating iDevice to iOS 12
We will highlight a few tips and tricks that have proven useful in the past when dealing with Bluetooth problems.
Before proceeding to troubleshoot, you may want to make sure that there are no interference conditions as highlighted in this Apple White paper that could be causing your Bluetooth problems.
If you face any of the Bluetooth issues mentioned above, try each of the following steps until the issue resolves. For stubborn problems that won’t go away, you may need to back up your iPhone or iPad and restore it using iTunes.
Bluetooth not Working after iOS 12 Update, How-To Fix
The best place to start troubleshooting Bluetooth issues is with your iPhone or iPad. Before proceeding further, test if you can connect the Bluetooth accessory with an iPad that’s on an older iOS version to see if it works.
You can also test by connecting a friend’s iPhone, running iOS 12, to the Bluetooth accessory to see if it works. This will give you some ideas around whether the problem is with the Bluetooth accessory, or if it localized to your device running iOS 12.
- Quick Reset– The first and foremost thing to do following a successful installation of the iOS 12 update is to do a quick forced-restart of your device. On the older iPhones, you will do this by pressing the Home and on/off button together for 10 seconds or so till you see the apple logo appear. Release the buttons when you see the logo and let your iPhone startup. If you are using iPhone 7/8/X models, please check our iPhone reset guide for the steps.
- Toggling Bluetooth mode– If you are having issues with discovering your Bluetooth device on your iPhone, sometimes a simple toggle can do wonders. Tap on Settings > Bluetooth and turn off your Bluetooth. Next, Switch off your device and turn it back on followed by enabling the Bluetooth in the settings. Check and see if your Bluetooth device now shows up under ‘MY DEVICES’ in the Bluetooth settings. Please make sure to toggle the Bluetooth using the Settings app and not via the control center.
- Reset Network Settings – Start by tapping on Settings > General > Reset and choose ‘Reset Network Settings.’ Please note that you may have to re-enter your Wi-fi name and credentials once the reset process is done.
- Pair and unpair the Bluetooth Device – If you can see your Bluetooth device on the list under ‘MY DEVICES’ in settings, but you are experiencing connectivity issues, you can reset the Bluetooth device. Tap on the ‘i’ on the right-hand side of the row and choose ‘Forget This device.’ Switch off and restart your iPhone and then try connecting again to the Bluetooth device to see if it works for you.
One tip that seems to be working for some users is to unpair the Bluetooth device by following the above step and then reset all Network connections before attempting to pair the Bluetooth device again with the iPhone. Give it a try and see if that does the trick for you.
If you are still having issues and have tried connecting your iPhone to other Bluetooth devices without any results, you may want to consider backing up your device and performing a clean restore of your iDevice.
iPhone Bluetooth Not Working in Car with iOS 12, Tips to consider
If the Bluetooth issue primarily happens with connections to your automobile, you can read Apple’s guidelines around how to deal with this issue.
Apart from the guidelines from Apple in the article link, you can also check and see if your car has settings to add and delete devices to CarPlay. If you have the feature, you may want to remove your iPhone from your Car’s memory and then re-add it back to see if the issue gets resolved.
We removed the Bluetooth profile for the car from the iPhone Bluetooth settings ( Under My devices), as well as removed the phone’s profile from the car’s Bluetooth. Restarted the iPhone and then connected without the Contact sync feature of the car’s Bluetooth. The issue was resolved!
One important tip is when you are re-pairing your iPhone with your Car’s Bluetooth, skip the step when it comes to allowing contacts to be synced.
Quick Workaround for Car Bluetooth Issues with iPhone
When we had bluetooth issues, where it randomly would stop and then re-connect, manually disabling and enabling bluetooth settings on the iPhone did the trick, however, while connecting to the car, the BT issues showed up again. What worked is to remove the iPhone from the car’s bluetooth settings, added it back again and disable the contact sync feature of the car’s bluetooth. We are hopeful that this issue has been fixed with the latest iOS 12 Update.
We didn’t see as many CarPlay issues when testing with iOS 12 Beta. Hopefully, the problems that were seen in iOS 11 have been resolved.
