WA Tweaker is a tiny app that can activate all the 'hidden' features in the beta version of WhatsApp. Of course, to use this app you will need a rooted Android device, or almost all of the app's features simply won't work correctly.
Using WA Tweaker is easy. First, close WhatsApp and enable airplane mode. Then, simply open WA Tweaker, enable whatever features you want, and reopen WhatsApp. And that's it! After that, simply sit back and enjoy all your new features that were disabled by default.
That being said, it's important to remember that all the features WA Tweaker can enable are ALREADY in the WhatsApp app, albeit inactivated. In other words, WA Tweaker DOES NOT add any features to WhatsApp that was not already put there by the developers.
Get the most out of WhatsApp with WA Tweaker, the latest version of WA Tweaks (a now outdated app). Not only that, but despite how it may appear at first glance, it's a very easy app to use. It won't even take two minutes to enable all kinds of interesting hidden features!
