If you’ve had a smartphone for any reasonable amount of time, you’ve probably installed and uninstalled more apps than you care to remember. Here’s how to access a list of all the apps you’ve installed on your Android phone(s) over time.
This feature is built into the Google Play Store, so you can actually take a peek at the entire list from any device logged in to your Google account. Even apps that you installed on your first Android phone should show up here (assuming they’re still available for download, of course). Also, since it’s part of the Google Play Store, the process will be the same on basically every device.
