Hello. My mobile phone turned on vibration and sound, but it still didn't vibrate when I called. What is the reason?

Samsung mobile phones generally recommend the following operations:

1. Try to adjust the vibration intensity of the incoming call to an appropriate volume.

2. Standby-Phone-Menu-Call Settings-Call Prompt-Answer Vibration is checked.

3. Try to turn off the phone and restart it.

4. Check whether incompatibility may be caused by installing third-party software.

5. If the problem still exists, it is recommended that you back up data (such as contacts, text messages and photos) and restore factory settings (Settings-Reset-Restore factory settings).

6. If the problem still exists after the above operations, please send your mobile phone, purchase invoice and maintenance card to Samsung Service Center for professional inspection. The address information/customer service telephone number of Samsung Service Center can be inquired in the following ways: Please log in to Samsung official website-click on the after-sales service in the upper right corner-click on the search Samsung Service Center-select the product you want to inquire and the province and city where you are located to search.

Tip: If there is no service center in your city, please contact the after-sales service centers in neighboring cities first and ask if you can check and repair by mail or express delivery.
