1. To find deleted apps on an Android device, you can follow these steps:

    Google Play Store: Open the Google Play Store app on your device. Tap the menu icon (usually three horizontal lines) in the top-left corner, then select "My apps & games." Here, you'll see a list of apps you've previously installed, including those you've uninstalled.

    Play Store Library: In the "My apps & games" section, switch to the "Library" tab. This tab shows a comprehensive list of all apps you've ever installed using your Google account, even if they're no longer on your device.

    Settings: On some Android devices, you can also check in the device's settings. Go to "Settings" > "Apps" or "Applications" (the name may vary depending on your device manufacturer). Here, you might find a list of "Disabled," "All," or "System apps." Look through these lists to find any apps you've previously installed.

    Google Account: You can also check your Google account's activity. Visit the Google Play Store website on a computer or mobile browser, log in with the same Google account used on your Android device, then navigate to the "My apps & games" section. This will show you a list of previously installed apps.

    App Backup Services: If you've used any app backup services or solutions, such as Google's built-in backup or third-party apps, you may be able to restore deleted apps from there.

    Keep in mind that you can only reinstall apps that you've previously downloaded and installed through your Google account. If you've installed apps from sources other than the Google Play Store, they may not appear in these lists, and you might need to find them through alternative means.
