If you're using it as a secondary WhatsApp, then uninstall the original WhatsApp.But if you want to use Fmwhatsapp as your primary messaging app, you can't uninstall it like a regular app because of dual WhatsApp.
To remove FM WhatsApp from android phone, just go to the play store and search for Clean Master or any other cleaner app (the free version will also do).
Now simply open that cleaner app and select FM WhatsApp in its process list(See the second screenshot below).
After selecting, click on the clean button. (Note: All you r chats, photos, etc. WILL BE REMOVED ). We can see immediately that Louvre was the most popular in the world with around 8 million people. This was followed by a marked increase to around 9 million in 1995.
Over the next five years, the figure decreased to under 8,5 million. However, this trend proved negligible as the viewing figure then rose again. It reached a peak of 9,5 million in 2015.
