Steps to Install Apps from External Sources
Enable Installation from Unknown Sources:
Open Settings: Go to the Settings app on your Android phone.

On older Android versions (pre-Android 12): Go to Security or Privacy - Install Unknown Apps or Unknown Sources.
On Samsung devices: Go to Settings - Apps - Menu (three dots) - Special Access- Install Unknown Apps.
Select the App: Choose the app you’ll use to install the external app (e.g., a browser like Chrome, Firefox, or a file manager).
Allow Permissions: Toggle on Allow from this source for the selected app. You may need to confirm this action.
