Final answer:
To enable overlay permission in Android 12, open the Settings app, navigate to Apps, select the desired app, tap on Permissions, go to Advanced, and toggle 'Display over other apps' or 'Appear on top.'
Step-by-step explanation:
To enable overlay permission in Android 12, you must access your phone settings. Start by opening the Settings app on your Android device. Then, go to Apps & notifications or simply Apps, depending on your device's interface. Tap on See all apps, App info, or Manage apps to view all installed applications.
Select the app for which you want to enable overlay permission. Now, tap on Permissions, and go to Advanced or look for Other permissions. Here, you should find an option that says 'Display over other apps' or 'Appear on top'. Toggle this option to enable it, allowing the app to display content over other running apps.
Please note that some apps may not function correctly without this overlay permission, while others may use it for intrusive advertisements, so it's important to grant this permission judiciously.
