+## Kiosk Mode (Device Owner) Setup
+
+To use the **true Kiosk Mode** (Lock Task Mode) without system confirmation prompts, the Schnappix app must be set as the Android "Device Owner". This requires connecting the tablet to a PC via USB and using `adb`.
+
+**Prerequisites:**
+1. The Android tablet must have no other accounts (like a Google Account) configured. It is highly recommended to start with a factory-reset device.
+2. Developer Options and USB Debugging must be enabled on the tablet.
+3. The Schnappix APK must be installed on the tablet.
+
+**Setup Command:**
+Run the following command in your terminal/command prompt while the tablet is connected:
+
+```bash
+adb shell dpm set-device-owner de.orfel.schnappix/expo.modules.kioskmode.AdminReceiver
+```
+
+If successful, the terminal will output `Success: Device owner set to package de.orfel.schnappix`. You can now safely disconnect the tablet and toggle the Kiosk Mode in the app's Admin Dashboard.
+
+*Note: Once set as Device Owner, the app cannot be uninstalled normally. You must either factory reset the device or implement a programmatic way to remove the active admin status.*

 ## Photo Frames — Setup Guide

 Schnappix supports custom photo frame overlays. Frames are transparent PNG images that are layered on top of photos before saving or printing.
