Samsung provides us a feature in Galaxy Phones to use two WhatsApp Numbers in one phone without using any third party app. Some of you may already know this, but I am writing this post to tell the people who don't know this feature.
How to use:
1. Open Settings
2. Click on Advanced Features
3. Click on Dual Messenger
4. Enable the WhatsApp Option (Original WhatsApp needs to be installed first)
5. Once you enable, you can see a new WhatsApp icon in your Apps Screen.
6. You can now use Two WhatsApp Account in One Phone without any App!
