''The following guide aims to describe in detail the settings and usage options of microG as implemented system-wide in VollaOS.''

VollaOS is a privacy-focused operating system based on Android, which integrates microG as an optional alternative to Google Play Services. This guide is intended for users who want to understand and optimally use microG’s features while maintaining privacy. It takes into account the specific integration in VollaOS, where microG can be enabled or disabled as needed.

= 1. Introduction to microG in VollaOS =
VollaOS is a “de-Googled” Android operating system that does not come with proprietary Google services (Google Play Services) pre-installed. Instead, it offers microG as an open-source alternative to run apps that require Google services without the privacy drawbacks of Google Play Services. microG is designed to provide only the necessary APIs, send anonymized data, and consume fewer resources.

In VollaOS, microG is integrated system-wide but disabled by default in the system settings to ensure maximum privacy control. Users can enable and configure microG via the settings to enable features such as push notifications, location services, or compatibility with specific apps.

'''Key features of microG in VollaOS:'''
* Privacy: No tracking of user activities, unlike Google Play Services.
* Modularity: Individual components (e.g., location, push notifications) can be enabled/disabled.
* Compatibility: Enables the use of many apps that require Google Play Services (e.g., banking apps, messengers).
* Resource-efficient: Lower battery and memory consumption compared to Google services.

= 2. Prerequisites =
Before configuring microG in VollaOS, ensure that:
* Your Volla Phone is running the latest version of VollaOS.
* You have basic knowledge of the Android user interface.
* You know which apps require Google services (e.g., banking apps, WhatsApp, YouTube).
* The Aurora Store is up-to-date to obtain apps compatible with microG.

'''Note:'''
Since VollaOS integrates microG system-wide, no manual installation is required, unlike other custom ROMs (e.g., LineageOS for microG). You only need to adjust the settings.

= 3. Enabling microG in VollaOS =
To use microG, you must first enable it. Follow these steps:

'''Open the Settings:'''
* Go to the “Settings” app on your Volla Phone.
* Scroll to “Apps” and then to “Manage microG” (depending on the VollaOS version).
* Enable or disable it using the toggle button.

'''Find the microG Settings:'''
* In VollaOS, there is a dedicated menu item under “System > microG Settings.”
* Open the “microG Settings” app, which is pre-installed system-wide.

'''Enable microG:'''
* When opening the microG Settings for the first time, you may be prompted to grant permissions (e.g., access to location, phone status). Confirm these.
* Enable the main component “microG Services Core” (GmsCore) by setting the toggle to “On.”
* Optional: Enable “Google Cloud Messaging” and “Google Device Registration” if you need push notifications (see Section 4).

'''Perform Self-Check:'''
* In the microG Settings, there is a “Self-Check” section.
* Tap it to verify that all necessary components are correctly installed.
* Ensure all checkboxes are ticked. Typical points:
** System supports signature spoofing: VollaOS supports this by default.
** microG Services Core installed: Should be present.
** UnifiedNlp registered: For location services.
** Permissions granted: Ensure all permissions are granted.
* If a checkbox is missing, follow the app’s instructions (e.g., manually grant permissions).
