Step by Step Tutorial: Enabling Pixel Unknown Sources

Before diving into the steps, it’s important to understand that enabling unknown sources can be a bit risky since it opens up your phone to potential security threats. However, if you’re cautious about where you download apps from, this can be a great way to access apps that aren’t available on the Play Store.

Step 1: Open Settings

Navigate to the Settings app on your Google Pixel 4A.
Opening Settings is the gateway to all the customization and control options for your device, including security settings.

Scroll down and find the ‘Apps & Notifications’ option, then tap to open it.
This section houses all the settings related to app permissions, notifications, and special app access.

Step 3: Access Special App Access

Within ‘Apps & Notifications’, find and select ‘Special App Access’.
‘Special App Access’ is a hub for adjusting privileges that apps can have on your device, such as modifying system settings or accessing usage data.

Step 4: Tap on Install Unknown Apps

In the ‘Special App Access’ menu, scroll down and tap on ‘Install Unknown Apps’.
This option specifically controls which apps can install other apps from unknown sources.

Step 5: Choose the Browser

Select the browser you’ll use to download apps from unknown sources, like Chrome or Firefox.
By selecting a browser, you’re giving it permission to install apps from sources other than the Play Store.

Step 6: Toggle Allow from this Source

Turn on the switch next to ‘Allow from this source’ to enable installations.
By toggling this switch, you’re allowing the selected browser to install apps from any source, not just the ones vetted by Google.

After completing these steps, your Google Pixel 4A will be able to install apps from unknown sources. Remember to download apps only from trusted websites to avoid potential security risks.
