How to clear the Bluetooth cache on your phone or tablet to fix issues with your connection

• You can clear the Bluetooth cache on your smartphone or tablet to fix issues with your Bluetooth connection.
• On an iPhone or iPad, clear the Bluetooth cache by unpairing all your Bluetooth devices and then restarting the device.
• On an Android device, you can unpair your devices, but you can also clear the cache more thoroughly through the Apps menu.

If you're having trouble pairing a new $4 device, or staying connected to one you've already paired with, it might mean the Bluetooth cache on your device has been corrupted.

Luckily, clearing the $4 cache is easy to do, and should solve common connectivity issues. Here's how to do it on your iPhone, iPad, or Android device.

How to clear the Bluetooth cache on an iPhone or iPad

1. Open the Settings app and tap Bluetooth.

2. If you're having trouble with a specific device that's already paired, find it in the My Devices list and tap the "i" icon to its right, then tap Forget This Device.

3. If your problem with Bluetooth is more general - for example, you can't pair any new devices - forget every Bluetooth device in the My Devices list. (You'll need to re-pair them again later.)

4. $4 or $4 to clear the associated cache.

After your iPhone or iPad restarts, the Bluetooth cache will be cleared and you can re-pair your devices to use them again.

How to clear the Bluetooth cache on an Android phone or tablet

1. Start the Settings app.

2. Tap Connections and then tap Bluetooth.

4. If your problem with Bluetooth is more general - for example, you can't pair any new devices - unpair every Bluetooth device in the Paired Devices list. (You'll need to re-pair them again later.)

There's also a more thorough way of clearing the Bluetooth cache by going through the Apps menu.

1. Open the Settings app, or go back to the main settings page.

2. Tap Apps.

3. Tap the menu icon and then choose Show system apps.
