Vanced microG is an app installed with other apps such as Vanced or Vanced Music. This app consists of a modified Google Mobile Services (GMS) so the Vanced app can work correctly with your Google account. With the app, you can sync your account with the modified app and save information such as your history, subscriptions, or where you left off watching a video.
As the name implies, Vanced microG is based on the microG project. This project consists of reimplementing Google Play Services without Google being present. This means you can use apps that require Google services on devices that don't usually support it.
You can modify various parameters from the app settings, such as choosing the Google account you want to use, deciding if you wish to enable Google device registration, or disabling the double Cast icon that may appear by mistake.
If you want to enjoy Vanced on your smartphone or tablet and you don't have a rooted device, downloading the Vanced microG APK is a must. If your device is rooted, you do not need to install microG for Vanced to work.
