How do I stop a Samsung phone from playing a repeating dial tone sound?
Answer
A repeating dial tone on a Samsung phone usually comes from call or system sound settings, Do Not Disturb / repeat callers options, or audio leaking from a Bluetooth headset or car connection. Check Sounds and vibration first, then turn Bluetooth off to see if the tone stops.
Before you start: stop right away if…
- Stop before factory resetting unless you have backed up photos and accounts and understand what will be erased.
Follow these steps
Review Sounds and vibration
Go to Settings > Sounds and vibration. Check ringtone, notification sound, system sound, and keypad tones, and change or turn off anything that could play a dial or call tone.
You should see: Unusual call-like tones are turned off or replaced with normal sounds.
Check Do Not Disturb and repeat callers
Turn Do Not Disturb off temporarily and open its exceptions. If repeat callers or similar call allowances are enabled, turn them off and listen again for a few minutes.
You should see: The repeating dial tone stops, or it continues with DND off.
Disconnect Bluetooth audio
Turn Bluetooth completely off and remove nearby earbuds, car audio, or speakers. Wait a few minutes to see whether the tone was coming through a paired device.
You should see: The tone stops when Bluetooth is off, pointing to a connected audio device.
Test in Safe Mode
Restart the Samsung phone in Safe Mode using your model’s button method, then listen for several minutes. If the tone stops in Safe Mode, a third-party app is likely involved.
You should see: The sound is gone in Safe Mode, or it still happens with only system apps running.
Update software and the Phone app
Install any available system update and update the Phone app from the Play Store or Galaxy Store, then restart normally and test again.
You should see: The repeating dial tone no longer plays after updates.

Extra tips
What to look for: A repeating outgoing dial tone or call-progress sound with no active call on screen, especially after connecting Bluetooth devices or changing sound settings.
Before you change anything: Note whether the sound happens only with Bluetooth earbuds, a car kit, or the phone speaker. Avoid a factory reset until sound and Safe Mode checks are done. Update the Phone app only from the Play Store or Galaxy Store. Never share account passwords or codes with unexpected callers.
