1. RESTART THE PHONE
Like all the troubleshooting processes, begin by restarting your Samsung Galaxy smartphone. That should fix any temporary glitch causing the vibration issue.
2. ENABLE VIBRATION
If your phone doesn’t vibrate when you receive a new call, you must ensure the ‘Vibrate while ringing’ setting is enabled. It’s possible you have disabled the vibration by mistake and forgot to enable it. To do so, go to Settings > Sounds and Vibration. Enable the toggle for Vibrate while ringing. If it’s already on, disable it and enable it again.
Similarly, Android allows you to disable or enable vibration separately for various functions such as touch interactions, keypad, keyboard, etc. You must manually check that the vibration settings for the required functions are enabled. For that, go to Settings > Sounds and vibration > System sound/Vibration control. Enable the required toggles.
3. CHECK INDIVIDUAL APP SETTINGS
If vibration feedback doesn’t work for a particular app, like the Messages app, you should check the app’s settings. Android phones let you customize the notification settings separately for each app. Vibration must have been disabled accidentally for the app.
There are two ways to check it. Firstly, you can open the app settings directly from the app and enable vibration under Notification settings. Alternatively, go to phone Settings > Apps. Tap on the problematic app. Then tap on Notifications.
You will find various notification categories. Tap on the suitable one. In the case of messaging apps, tap on Incoming messages. Make sure to tap on the text and not the toggle. Turn on the toggle next to Vibrate. If it’s on, disable it and enable it again.
4. UPDATE PHONE SOFTWARE
At times, even a software update can be responsible for vibration not working. To fix it, you will need to update your phone to the latest software. For that, go to Settings > Software update > Download and install. If an update is available, install it.
5. RESET ALL SETTINGS
This will reset all the settings on your phone to their default values.
To reset settings, go to Settings > General Management > Reset > Reset all settings.
6. CHECK THE VIBRATION MOTOR
If the above solutions do not help, you will need to test if you have a faulty vibration motor on your Samsung Galaxy phone. Here are the steps:
Step 1: Open the dialer or Phone app. Dial *#7353# or *#0*#. No need to press the call button. The code will activate automatically.
Step 2: A white screen with various options will open. Tap on Vibration.
