After going through a number of websites, I couldn't found the best way to backup my contacts. I have tried many different methods and tried to use apps such as MCBackup from the Play Store, but none of them was as per my requirements. For instance, MCBackup duplicated my phone contacts and whatsapp contacts. Then, I started looking for any options within my phone without the help of any app. To my surprise, I found the below method, which is easy and doesn't require the help of any app.
