How to Fix Samsung Galaxy Bluetooth Audio Cutting Out During Calls

Samsung Galaxy Bluetooth audio cutting out during calls is usually caused by a bad Bluetooth profile handshake, aggressive battery optimization, outdated earbuds or car firmware, or interference from Wi‑Fi and nearby devices. The fastest fix is to re-pair the accessory, reset Bluetooth settings, disable battery restrictions for call-related apps, and install Samsung and headset updates.

🤔Note:

If Bluetooth audio works fine for music but fails during phone calls, the issue is usually related to the hands-free calling profile rather than the speaker hardware itself.

Steps

Remove and re-pair the Bluetooth device.

Delete the headset, earbuds, or car kit from Bluetooth settings. Restart both devices. Pair again and test a call before restoring extra audio features.
Reset network and Bluetooth settings.

Open Samsung settings and reset network settings. Reconnect Wi‑Fi and Bluetooth devices afterward. A Samsung bluetooth audio cut during calls often stops after a clean Bluetooth profile reset.
Disable battery restrictions for phone and companion apps.

Set the Phone app, Bluetooth companion app, and wearable app to unrestricted battery use. Galaxy bt call drop problems often appear when background services are paused.
Update phone software and accessory firmware.

Install the latest One UI update and check firmware inside the earbuds, headset, or car system app. Bluetooth call glitch reports commonly involve outdated firmware on only one side of the connection.
Test with Wi‑Fi off and nearby Bluetooth devices disconnected.

Make one short call with 2.4 GHz Wi‑Fi disabled and other paired devices turned off. Interference often causes choppy or dropping call audio.

Common Issues and Fixes

Audio cuts only during calls: Call profile handshake failure is likely. Re-pair the device and confirm the Bluetooth device has Calls enabled, not only media audio.
Calls switch from headset to speaker randomly: Battery optimization or wearable app sleeping is a common cause. Remove battery restrictions and allow background activity.
Problem started after an update: Corrupted Bluetooth cache or changed codec behavior may be involved. Reset network settings and reboot both devices.
Only one car or headset has the problem: Accessory firmware incompatibility is likely. Update the accessory and test with another phone to isolate the source.
Audio stutters in crowded areas: Radio interference is a common cause. Turn off nearby wearables, smartwatches, or 2.4 GHz Wi‑Fi during testing.

Option	Best For	Limitation
Re-pair device	Sudden call drops	Temporary if firmware is old
Reset network settings	Persistent Bluetooth call glitch	Removes saved Wi‑Fi networks
Disable battery optimization	Random disconnects mid-call	Does not fix bad accessory firmware
Firmware updates	Repeat issues on one headset or car	Update may not be available

Quick Tips

Multipoint connections: Bluetooth multipoint can interrupt call routing when a headset is connected to a tablet or laptop at the same time.
Nearby device scanning: Some Galaxy models handle call audio better after turning off nearby device scanning in connection settings.
Signal blockage: Cases and metal dash mounts can reduce signal stability when the phone is in a pocket or mounted deep inside a console.
Call profile focus: If regular music playback works but calls fail, the problem is usually the hands-free call profile, not the speaker hardware.

💡Protip:

When testing a Bluetooth call issue, disconnect other paired devices first and make a short call in a low-interference area. This helps confirm whether the problem is caused by pairing conflicts or radio congestion.

Why does Bluetooth audio cut only on Samsung calls?

Call audio uses a different Bluetooth profile than music playback. A device can stream music normally while the call profile fails or keeps reconnecting.

Can a factory reset fix galaxy bt call drop?

A factory reset can help when system settings are heavily corrupted, but accessory firmware and interference problems will remain. Backup should be completed before any full reset.
