There are the following ways to check the warranty period of the cell phone:
1, through the invoice on the purchase time deferred by one year to arrive at (if there is an extended warranty service, you need to add the time of the extended warranty);
2, go to the Settings - System Management/My Device - Customer Service - Electronic Warranty Card - View Warranty Period;
3, go to the official website of the vivo query page, the authenticity page, enter the imei code query. Input the imei code to check, you can check the remaining warranty period, you can click on the specific web link to view;
4, if you encounter no invoice, lost the box, can not be turned on, etc., you can bring the machine to the vivo customer service center to check.
You can go to the Vivo official website/Vivo Mall APP--My--Outlet Inquiry or click on the web link and select the current city to get the address and contact information of the service center. It is recommended to contact them by phone in advance before going there to avoid running empty, plan your trip reasonably and travel safely.
