Method 2
In this particular method, this feature is pre-built with the WhatsApp app itself, quite different from method 1 above.
To make this work using method follow the settings below…
- Open WhatsApp messenger
- Go to settings >> Select Accounts >> Privacy
- Turn off read recipients by checking the box.
NB: If you turn off read recipients, you won’t be able to see read recipients from other people. Read recipient are always sent for group chat.
This trick works well on Android and iPhone, BlackBerry users can give this trick a try as well. I believe with the two methods explained above you should be able to read WhatsApp messages without your recipients knowing at all!
