As far as removing an annoying emoji app that takes over your phone. You're in luck if you downloaded it from Goggle play store. It took me three days of trying to navigate through the complicated security, device manager etc.. advice I got from this forum... Simply go into google play store check your account for "installed apps" and uninstall it. Voi la !! The annoying little app safe gaurds itself by not allowing you to uninstall it through your app settings
I hope this helps. It drove me bonkers !!!
