But some older apps, or smaller apps that might not be able to gain approval for the Play Store for one reason or another, can provide a lot of value to their users.

Our guide below will show you how to enable app installation from unknown sources so that you can install an app from Google Chrome, Google Drive, or a handful of other locations.

Pixel Unknown Sources – More Information

While installing apps from unknown sources can be OK in some situations, it is also a potentially risky decision. Apps that you install on your device can contain viruses or steal your information, which is why the approval process for the Google Play Store is so important. Apps from unknown sources may not update as easily as Play Store apps, so it’s possible that you will need to manually reinstall an app that was installed in this manner. If you are installing an app from an unknown source and it’s important to you to have access to that app in the future, be sure to bookmark the location for the app download. Apps that you install from unusual locations can sometimes be hard to find again, and popular apps can often be targeted by individuals that create copies of those apps and include malware. The ability to install from unknown sources is something that has been a part of the Android operating system for a while. So while our guide is focused specifically on the Google Pixel 4A you can also enable unknown sources through the Settings > Apps & notifications menu on other devices, such as the Pixel 3, Pixel 3 XL, and more. One you have completed this process to enable unknown sources you can navigate to the app location and perform the indicated steps to install the app on your device. When you install unknown apps on your Pixel 4A, they are going to be in the APK file format. This is the same type of file that you use to install approved apps, but many communities that share information on how to install unknown apps often use the term “apk” to indicate an app file.
