Overview
If your device vibrates on incoming calls but does not produce any ringtone even though volume settings are at maximum, it typically indicates a notification permission, sound mode, or device-specific configuration issue. This guide will help you check and fix the problem.
Troubleshooting Steps
✅ 1. Verify Silent or Do Not Disturb Mode Is Off
-
On Android:
-
Swipe down from the top to open Quick Settings.
-
Make sure Do Not Disturb is turned OFF.
-
Confirm the ringer icon is set to “Sound” (not “Vibrate”).
-
-
On iPhone:
-
Check the Mute switch on the left side of the phone.
-
In Settings > Focus > Do Not Disturb, make sure it is disabled.
-
✅ 2. Check App Notification Permissions
-
Go to:
-
Settings > Apps > EVO Voice (or your calling app) > Notifications
-
Confirm that “Allow Notifications” is enabled.
-
Confirm that Sound is set to ON.
-
✅ 3. Select a Valid Ringtone
-
Go to:
-
Settings > Sound & Vibration > Ringtone
-
Choose a ringtone other than Silent or None.
-
Tap Play to confirm it produces sound.
-
✅ 4. Verify Bluetooth Output
-
If connected to Bluetooth (headset or speaker), calls may ring there instead.
-
Turn off Bluetooth to see if calls ring through the phone speaker.
✅ 5. Test the Phone Speaker
-
Play music or a video to confirm the speaker works.
-
If no audio plays, this is a hardware issue, not a settings issue.
✅ 6. Reboot Your Phone
- Restarting can clear temporary audio routing or notification conflicts.
✅ 7. Reinstall the EVO Voice or Softphone App
- Uninstall and reinstall the app to reset notification channels.
Extra Tip (Android)
On some Android phones, you must:
-
Go to Settings > Apps > EVO Voice > Battery
-
Enable Allow background activity
-
Disable Battery optimization
This ensures ringing alerts can trigger when the app is in the background.
If the Problem Persists
Provide:
-
Your device model and OS version
-
Whether other apps ring normally
-
Confirmation that you tested the speaker separately
Then contact EVO Support for further assistance.
