Fix: Bluetooth calls not working on Android 12

Android Pie’s Bluetooth is a bit of an issue for many users. In the most basic sense, these devices don’t automatically connect to your phone when you first use it. Additionally, if your device gets too far away from your Android device (or vice versa), calls end and are replaced with only audio.

The “Bluetooth disconnects when incoming calls” is a problem that many Android users have been experiencing for quite some time. The issue has been fixed with the latest update to the operating system, but it’s still worth noting.

Fix: Bluetooth calls not working on Android 12

Given the present state of things, with all major OEMs eliminating headphone connectors like the plague, many people prefer Bluetooth audio. If not for the audible output (which isn’t always equivalent to wired alternatives), then for handsfree calls. It seems that some Android 12 users are having troubles with this, since Bluetooth calls are no longer functioning.

  1. Restart your device.
  2. Firmware should be updated
  3. Remove the headphones/car system and reconnect them.
  4. Disable HD audio.
  5. Bluetooth A2DP Hardware Offload is disabled.
  6. Reset Network Configuration
  7. Restore your gadget to its original factory settings.

In calls, Android 12 disrupted Bluetooth audio.

Solution 1: Restart your phone and delete the cache.

Let’s begin by restarting your computer. Some people reported that activating and then removing Airplane mode solved the issue, so it’s worth a try.

The next step is to activate System services in Settings > Apps > All apps. After that, find the Bluetooth app and delete its cache and data. Reboot your device and try Bluetooth once again. You should also see if there are any improvements if NFC is turned off. Some claim that disabling NFC improves the connection significantly.

Continue to the following step if the problem remains and Bluetooth audio in calls is not functioning or is crackling.

Solution 2: Install the latest firmware.

The next step is to look for any potential upgrades. There have been several complaints of Bluetooth difficulties after the upgrade to Android 12. On Android 11, the concerns were non-existent.

OEMs should have fixed the issue with updates, which is why you should keep your device up to date. In Settings > System, check for updates and install any that are available.

Solution 3 – Disconnect the headphones/car system and reconnect them.

It’s difficult to determine the particular origin of the problem, however removing and re-pairing devices frequently solves the problem. Remove the problematic device (whether it’s wireless headphones or a vehicle system) from the list of linked devices and attempt pairing again.

To delete and re-pair your Bluetooth device with your phone, follow these steps:

  1. Open the Settings menu.
  2. Bluetooth is a good option.
  3. Open devices that have been paired. To get the option to Unpair on various Android skins, you’ll need to be connected to the audio device. Turn on Bluetooth and connect to the headphones/car system if this is the case.
  4. Unpair may be tapped.Fix-Bluetooth-calls-not-working-on-Android-12
  5. Restart both your phone and the device with which you wish to link it. After that, go back to Settings > Bluetooth and link the audio device with it.

Solution 4 – Make phone calls possible

A toggle to allow or stop phone calls on a certain associated Bluetooth device is also available from some OEMs. Check to see whether Phone calls are enabled on that specific device.

This is how to make sure that a Bluetooth device can make phone calls:

  1. Open the Settings menu.
  2. Bluetooth is a good option.
  3. On the Paired devices list, choose your device.
  4. Toggle the phone calls on/off switch.Fix-Bluetooth-calls-not-working-on-Android-12

Disable Bluetooth A2DP Hardware Offload (solution 5)

Alternately, you may go a step farther and change the Bluetooth Developer settings. There are a number of parameters that you may simply set to System default. You may also change the codec to AAC and switch to AVCRP version 1.6 instead of the default 1.4.

Bluetooth A2DP Hardware Offload is the most significant and the one that generally solves the issue. That option must be disabled.

Here’s how to go to the Developer menu and change your Bluetooth settings:

  1. Go to Settings > About phone on your phone (or System).
  2. Seven times tap on the Build number.
  3. Return to Settings and look for the Developer options.
  4. Toggle off Bluetooth A2DP Hardware Offload by going to Disable Bluetooth A2DP Hardware Offload.

Reset Network Settings (Solution 6)

If none of the preceding procedures worked and your Bluetooth calls on Android 10 are still not functioning, you should reset your network settings. Keep take mind that this will wipe out any SSIDs and Bluetooth connections.

To restore Network Settings to their default settings, follow these steps:

  1. Open the Settings menu.
  2. Select between system and general management.
  3. Restart by pressing the Reset button.
  4. Then choose Reset Network Settings from the drop-down menu.
  5. Confirm your choice.

Solution 7: Restore factory settings to your smartphone.

Finally, if changing Network Settings does not solve the problem, the only option is to factory reset your smartphone. This won’t revert your smartphone to Android 11, but it should fix any difficulties that arose with the Android 12 OTA upgrade.

Here’s how to restore factory settings on your Android device:

  1. Make a backup of your data from your computer’s internal storage (photos can be saved to Google Photos, other media can be saved to an external storage or a PC).
  2. Select Settings > System > Reset from the drop-down menu.
  3. Choose Reset factory data (Erase All Data).1637858236_415_Fix-Bluetooth-calls-not-working-on-Android-12
