The Moto G 5G Plus, Motorola's most affordable phone at the moment, is getting an exclusive new app called Multi-Volume.
The app allows a user adjust the volume on a per-app basis and even mute some of them too. The app also automatically mutes some apps based on your usage patterns. There's also a slider in the volume pop-up on the right side of the screen for the app in the foreground and a user can adjust the volume of the notifications and calls separately.
XDA-Developers say that the app can't be side-loaded to other Motorola devices, but for now there's no word from the company whether the feature will be made available to the other phones.
