To recover uninstalled apps on Android:
Open Google Play Store. Click your Google account icon near the top-right corner of the screen.
Select Manage apps & device. Then, navigate to the Manage tab.
Change the first drop-down from Installed to Not Installed. It will display the apps you previously used but are currently not installed on your device.
Select the app you want to recover and click the Download icon.
If there are any missing files you want to recover, use data recovery software like Disk Drill, which is also compatible with Android and iOS devices.
