While the Google Play Store has a very large selection of apps that you can download to your Google Pixel 4A device, it does not contain every app that you might want or need to use on your phone.
If you have ever tried to install an app from outside of the Play Store then you may have encountered an issue where your phone was blocking you from doing so.
This is a security measure that is meant to protect your device, other apps, and personal information from potentially harmful applications that haven’t been verified through the Play Store.
But you can enable installation from unknown sources on a Pixel 4A by going to Settings > Apps & notifications > Advanced > Special app access > Install unknown apps > then choosing a source and enabling it.
Once you have completed those steps you will be able to go back to whatever location you were trying to install an app from and hopefully be able to successfully complete that installation.
Our guide below continues with more on using this unknown app installation process so that you can get the apps you need which may not be available in the Google Play Store.

Unless you know that you are going to be installing a lot of apps from unknown sources on your Pixel, then you may want to turn this setting back off when you are done.
If you have Google Pixel unknown sources enabled then you can go back to the Special app access menu and turn off app installation privileges for whichever app you have previously allowed.
When you install an app from an unknown source on the Web then it’s a good idea to save a link to that download location somewhere in case you need to install the app again in the future or install an update.
Since the Google Play Store traditionally manages app updates for the apps that you install from that marketplace you are going to be on your own when it comes to installing the updated version of apps that come from unknown locations.
The app files that you download and install on your Google Pixel smartphone are going to have a file extension of .apk.
The steps in this guide were performed on a Google Pixel 4A in Android 11, but many other Android devices and versions also have this ability. So even if you have a Google Pixel 2, Google Pixel 3, or one of the XL versions, you will still be able to adjust this setting on those devices if you need to install an app from outside of the Play Store.
