When you've enabled that feature, back out and try to install the app again, and it should work. In earlier versions of Android, such as Nougat, you'll have to manually toggle a global setting that allows installing from 'Unknown sources' in Settings (Settings -> Security -> check the box or slide the toggle for Unknown sources.). Your phone may indirectly ask if you'd like to change that for a given app, prompting you to enter settings and toggle the 'Allow from this source' setting, at which point you can then back out to the installation screen and proceed. In Android 8.0 Oreo and later, this is treated as a per-app permission. That's usually in Settings -> Security, or you can search in the Settings app for 'Install apps' or 'Install unknown apps.' On older versions of Android (Pre-Android 8.0 Oreo - consider upgrading for your own security if your phone is this old), you'll have to manually enable a separate toggle to install apps from unknown sources. Just tap the download notification to begin the process. When you've found the version of the app you need, installing it is sometimes as simple as downloading it from APK Mirror and, well. In Android 8.0 and later (including Android 9 and 10), installing from unknown sources is a per-app setting. That means while you'll be able to uninstall the current version of a given app, you won't be able to re-install an older version manually, and there's no simple workaround.

On Android, reverting an app to an older version is fortunately a pretty straightforward process, and we'll guide you through it here.įor many of our more technically-minded readers, this how-to isn't going to be presenting much in the way of new information, but it's still useful for those new to the platform or troubleshooting with these steps for the first time, especially if you aren't familiar with how Google's app bundles work. Be it because the new one is crashing, has introduced a new feature or option that's broken, or simply because you don't like the latest changes, there are ample reasons to revert an update.

Sometimes, you need to install an earlier version of an app on your phone.
