I recently installed Republic’s latest upgrade to my Moto MG4. Now when I turn my phone on I get an annoying announcement that disrupts everyone in the room. How do I silence this feature?

With the Nougat update, when the G4 starts up, the music and announcement of “Hello Moto” can seem loud. To mute this, open your phones settings, scroll down to Sound and tap on it. You will see an option for Power up Sound. You will be able to turn it off by sliding the button to the left.
