You can add the shortcut of a WhatsApp chat (contact or group) to the home screen of your Android device and here’s how:
In the “Chats” tab, tap the chat you want. In case, if you don’t have a chat for the contact you prefer in the “Chats” tab, then tap on “New chat” icon at the bottom and then tap on the contact you prefer.
Now, tap the overflow menu (three vertical dots) at the top.
Tap “More” which you can find beneath “Wallpaper.”
Hit “Add shortcut” which you can find beneath “Export chat.”
In the “Add to Home screen” popup, tap “Add.”
That’s all. Now, you can see that the chat shortcut is added to the home screen of your Android device.
Tap on it to open the chat directly.
