If you suspect that someone has installed a hidden app on your Android device, you can follow these steps to find and uninstall it:

- Go to your device’s “Settings” menu: You can usually access this by tapping the gear icon on your home screen or in the app drawer.
- Scroll down and tap on “Apps” or “Application Manager”: This will show you a list of all the apps installed on your device.
- Look for any apps with generic or suspicious names: Hidden apps may have generic names like “Calculator,” “File Manager,” or “System Update.” They may also have names that don’t make sense or seem out of place.
- Check for hidden or disabled apps: Some apps may be hidden or disabled, which means that they don’t show up in your app drawer. To see if you have any hidden or disabled apps, tap on the three-dot menu icon in the top right corner of the “Apps” or “Application Manager” screen, and select “Show system” or “Show disabled apps.”
- Uninstall any suspicious apps: If you find any apps that you didn’t install or that seem suspicious, you should uninstall them immediately. To do this, simply tap on the app and select “Uninstall.”
- Restart your device: After uninstalling any suspicious apps, it’s a good idea to restart your device to ensure that the changes take effect.

That’s it! By following these steps, you can find and uninstall hidden apps on your Android device. It’s important to regularly check your device for any apps that you don’t recognize or didn’t install, as they could be a sign of malicious activity.
