Bluetooth on the Galaxy A54 5G fails in the usual ways: a stale pairing, an accessory that is flat or connected elsewhere, and a software fault after an update. Turn Bluetooth off and on, forget the device in Settings, Connections, Bluetooth and pair it again, and make sure the accessory is charged and in pairing mode. For a car, delete the phone from the car's list and pair again. If music stutters, move away from busy 2.4 GHz Wi-Fi and keep line of sight. The A54 can connect to more than one device and uses Dual audio on some accessories; if sound goes to the wrong device, check the audio output in the media player.
Restart the phone and update the software, and, if the problem is persistent, reset Wi-Fi, mobile data and Bluetooth settings under Settings, General management, Reset. The A54 is a mid-range phone with a standard Bluetooth 5.3 radio, which is fine for headphones, car kits and watches, so the radio itself is rarely the problem and the accessory or the settings usually are. A pairing that keeps dropping after you move rooms is a range limit, since the radio's reach through walls is only a few meters. Wearables such as Galaxy Watches pair through the Galaxy Wearable app, and a watch that will not connect should be re-paired there rather than in Bluetooth settings.

Before you touch a setting
Record this first — changing settings destroys the evidence

- Whether the Galaxy Wearable app lists it as connected
- The A54's software version and the date of the last update
- Whether the break-up happens near a router or in an open area
Try in this order
0 of 9 completedReconnect through the right app
ReversibleFor a Galaxy Watch or Buds open the Galaxy Wearable app and reconnect there; other accessories use Settings, Connections, Bluetooth.
Forget the accessory and pair it again
ReversibleTap the gear beside its name, choose Unpair, put the accessory into pairing mode and select it from the list of nearby devices.
Clear the Bluetooth app's cache
ReversibleSettings, Apps, Show system apps, Bluetooth, Storage, Clear cache, then restart the A54; this wipes stale connection data and keeps your pairings list.
Resync earbuds with their case
ReversiblePut both buds in the case, shut the lid for ten seconds, then open it beside the phone to reconnect them together.
Delete old phones from the car
ReversibleOpen the car's Bluetooth menu, remove earlier phones to free a slot, and pair the A54 again.
Cut 2.4 GHz crowding
ReversibleMove the router's devices to 5 GHz or sit closer to the accessory if music stutters during calls.
Use the right app for Samsung wearables
ReversibleOpen the Galaxy Wearable app to reconnect a Galaxy Watch or Buds, because they manage their own connection.
Check the accessory's own app
ReversibleMany headphones have an app that updates their firmware, which cures dropouts.
Test with another phone
ReversiblePair the accessory with a different phone to find which side is at fault.

Stop boundary
When this stops being a self-service repair
- !If Bluetooth cannot be switched on at all after clearing its cache, take the A54 to Samsung
- !If only a single brand of headphones fails, update that brand's firmware before blaming the phone
- !A car that still refuses after a fresh pairing may need a software update from the carmaker
