Step by step

1. 

   Put the accessory in pairing mode

   The phone reminds you on the Bluetooth page: the device must be in pairing mode to be found. Keep it within about 10 metres.

   Done

2. Restart both devices

   Switch the accessory off and on, and restart the phone.

   Done

3. 

   Forget the device and pair again

   Settings, Connections, Bluetooth: tap the gear next to the device, Forget device, then pair it again from Available devices.

   Done

4. 

   Check Block pairing requests

   Three dots, Advanced settings. Make sure it is off, or new devices cannot pair.

   Done

5. Install the accessory's app

   Some devices, such as Galaxy Watch and Buds, need their own app, for example Galaxy Wearable.

   Done

6. 

   Reset Wi-Fi and Bluetooth settings

   Settings, General management, Reset. Every paired device has to be paired again afterwards. Steps: how to reset network settings on a Samsung Galaxy phone.

About this guide

Most failed connections come from the accessory, not the phone: it is not in pairing mode, it is still connected to another phone, or its battery is low.

The screenshots are from a Samsung Galaxy A57 5G with One UI 8.5 and Android 16. Other Galaxy phones on One UI 8 use the same menus; on older One UI versions a few names and positions differ. Names of nearby devices are blurred. We only looked at these screens on our phone and changed nothing.

Good to know

Bluetooth control history, on the same Advanced settings page, shows which apps switched Bluetooth on or off.

In short: Pairing mode, restart both, forget and re-pair, Block pairing requests off, the accessory's app, reset Wi-Fi and Bluetooth settings.
