If your OnePlus 13 has gone silent, missing vibrations for calls and notifications, it can be easy to overlook important alerts. This is a common hiccup, especially with new software like OxygenOS 15, and the fix is usually straightforward.
Force Restart Your Phone
Before diving into settings, give your device a quick refresh. Press and hold the Volume Down button and the Power button together for about 10 seconds. Release them when you feel the phone vibrate and the OnePlus logo appears.
This simple reboot clears out any temporary software glitches that might be stopping the vibration motor. I'd start with this one, as it often resolves the issue in seconds.
Verify Your Sound and Vibration Profile
Your phone might be in a silent or "Do Not Disturb" mode. Swipe down from the top of your screen twice to open the Quick Settings panel. Look for the sound mode icon, it might say "Silent," "Vibrate," or "Ring."
Tap it to cycle to "Ring" mode. For more control, go into Settings > Sound & vibration and check that "Vibrate for calls" is toggled on. Also, ensure "Do Not Disturb" is not active, as it can silence vibrations.
Check the Vibration Intensity Settings
The OnePlus 13 lets you fine-tune how strong vibrations feel. If the intensity is set too low, you might not notice it. Open Settings > Sound & vibration > Vibration & haptics.
Here, you'll find sliders for "Call vibration," "Notification vibration," and "Touch feedback." Slide each one up to a higher level and test it out. Sometimes a recent update or app can accidentally lower these values.
Inspect App-Specific Notification Settings
If vibrations work for some apps but not others, the problem is likely in the app's own settings. Go to Settings > Apps > [App Name] > Notifications.
Make sure notifications are enabled for that app. Then, tap into the specific notification category (like "Messages" or "Incoming Calls") and check that the "Vibrate" option is turned on. Messaging apps like WhatsApp or Telegram have their own vibration settings buried here.
Update OxygenOS
Early software builds can have bugs that affect hardware functions like the vibration motor. OnePlus is typically quick to release patches. To check, go to Settings > About device > OxygenOS version > Check for update.
If an update is available, download and install it. It's a good practice to keep your OnePlus 13 updated anyway, as it improves stability and battery life. Make sure your phone is connected to Wi-Fi and has at least a 50% charge before updating.
Test in Safe Mode
This step checks if a recently installed third-party app is causing a conflict. To boot into Safe Mode, press and hold the Power button until the power menu appears. Then, long-press the "Power off" option on your screen.
Tap "OK" when prompted to reboot to Safe Mode. If your vibrations work normally in this mode, a downloaded app is the culprit. Restart your phone to exit Safe Mode, then try uninstalling apps you installed around the time the problem started.
Review Accessibility and Battery Settings
Certain accessibility features can alter vibration behavior. Go to Settings > Additional settings > Accessibility. Look for any features like "Turn off all vibrations" or "Vibration & haptic strength" that might be configured incorrectly.
Also, check battery optimization. Go to Settings > Apps, select the app, and open its battery usage settings to manage battery optimization. While you generally shouldn't disable optimization, see if any key apps (like your phone dialer or messaging app) are being aggressively restricted, which could delay or prevent vibrations.
Reset App Preferences
This resets all your app notification settings, permissions, and default apps without deleting any personal data. It can clear up conflicts. Navigate to Settings > Apps > See all apps > Menu (three dots) > Reset app preferences.
Tap "Reset apps" to confirm. Afterward, you'll need to re-grant notification permissions for your apps, but it often resolves quirky issues like this.
Check for Physical Damage or Case Interference
While less common, a physical issue is possible. Remove your phone case and see if vibrations return. A very tight or poorly designed case can sometimes dampen or completely stop the motor's movement.
Think back to any recent drops or exposure to water. The vibration motor is a small physical component that can be dislodged by a significant impact. If you suspect physical damage, this points toward a hardware repair.
Perform a Factory Reset (Last Resort)
If all else fails, a factory reset will wipe the phone back to its original software state. This will erase all your data, so you must back up everything important first. You can back up to your Google account or use OnePlus' built-in backup tool in Settings.
To reset, go to Settings > Additional settings > Back up and reset > Reset phone, then tap Erase all data. Follow the prompts. After the reset, set up the phone as new without restoring a backup immediately to see if the vibration works on a clean system.
