My new iPhone 12 is skipping over Bluetooth while others work fine

Bluetooth interference can potentially cause connectivity issues due to the disruption of the wireless communication between devices. Bluetooth operates in the 2.4 GHz frequency range, which is also used by various other devices such as Wi-Fi routers, microwaves, cordless phones, and even some baby monitors. When multiple devices are operating nearby and using the same frequency band, interference can occur.

To mitigate Bluetooth interference issues and reduce stuttering:

1. Minimize the number of active Bluetooth devices near each other. Switch off or move away devices that are not in use or causing interference.
2. Increase the distance between your Bluetooth devices (e.g., your iPhone and Bluetooth speaker/headphones) to reduce the impact of interference.
3. Keep your devices' firmware up to date, including your iPhone and any Bluetooth accessories. Manufacturers often release firmware updates that can improve the performance and stability of Bluetooth connections.
4. Objects like walls, furniture, or large metal surfaces can obstruct Bluetooth signals and contribute to interference. Ensure a clear line of sight between your devices to optimize signal strength.
5. Some Bluetooth devices allow you to manually switch to different channels within the 2.4 GHz range. Check the user manual or settings of your Bluetooth accessory to see if you can change channels to find a less congested one.
6. If your Wi-Fi router supports it, consider using the 5 GHz frequency band for Wi-Fi connections instead of 2.4 GHz. This can reduce potential interference between Bluetooth and Wi-Fi signals.

By implementing these steps, you can help minimize Bluetooth interference and improve the overall performance of Audio.

   1. When you reset network settings, previously used networks and VPN settings that weren’t installed by a configuration profile or mobile device management (MDM) are removed. Wi-Fi is turned off and then back on, disconnecting you from any network you’re on. The Wi-Fi and Ask to Join Networks settings remain turned on.
   2. To remove VPN settings installed by a configuration profile, go to Settings > General > Profiles & Device Management, select the configuration profile, then tap Remove Profile. This also removes other settings and accounts provided by the profile. See Install or remove configuration profiles on iPhone in this guide.
   3. To remove network settings installed by MDM, go to Settings > General > Profiles & Device Management, select the management, then tap Remove Management. This also removes other settings and certificates provided by MDM. See “Mobile device management (MDM)” in the iOS Deployment Reference.
   4. Reset your Network Settings. Tap Settings > General > Reset > Reset Network Settings. This also resets Wi-Fi networks and passwords, cellular settings, and VPN and APN settings that you've used before.

5. If the issue persists, you can try resetting all settings on your iPhone. This will not erase your data but will reset all personalized settings to their default values. Go to Settings > General > Transfer & Reset > Reset > Reset All Settings and confirm the action. Note that you will need to reconfigure your settings afterward. All settings—including network settings, the keyboard dictionary, the Home screen layout, location settings, privacy settings, and Apple Pay cards—are removed or reset to their defaults. No data or media are deleted.

   2. You can return settings to their defaults without erasing your content.
   3. If you want to save your settings, back up your iPhone before returning them to their defaults. For example, if you’re trying to solve a problem but returning settings to their defaults doesn’t help, you might want to restore your previous settings from a backup.
