# How to lockdown your devices onto Digital Signage Kiosk

Digital signage kiosk helps in addressing people at airports, malls, streets, and other public places in an easier way. It transforms your Android devices into images/video streaming screens, which enables you to play the media files in loops.

You can also trim, mute, and add custom background music to your videos. Transmission speed and animations can also be added, which helps in transforming your ideas into virtual reality. Moreover, you can change/remove the display content anytime using Hexnode.

 Notes:- The supported formats for media files are **JPG & PNG** for **images**, **MP4 & Matroska (MKV)** for **videos** and, **MP3 and OGG** for **audio**.
- The dimensions for the video files should not exceed ***1920×1080*** pixels (recommended).
- This feature is supported on **Android 5.0+** and **Android TV OS 5.0+** devices.
- Digital signage for Amazon Fire OS supports only streaming the image files.

- This permission should be granted for the Hexnode UEM during enrollment.
![Mange All Files permission on Hexnode UEM app](https:2020/05/Manage-All-Files.jpg "Manage All Files")[](https:2020/05/Manage-All-Files.jpg)

- When the Hexnode UEM/Hexnode for Work app is updated, ‘Manage All Files’ permission may not be granted. Hence, to avail file management and distribution functionalities, user should grant this permission when the Hexnode UEM app prompts while opening the updated app.
![Manage All Files Permission during update](https:2020/05/Manage-All-Files-grant-access.jpg "Manage All Files grant access")[](https:2020/05/Manage-All-Files-grant-access.jpg)

- If the screensaver or digital signage is configured with the kiosk policy and the ‘All Files Access’ is denied to the Hexnode UEM app, kiosk activation fails. To activate kiosk mode, you need to grant permission when the prompt ‘Kiosk Activation Failed’ appears on the device.
![Permission to activate kiosk mode](https:2019/01/Kiosk-activation-failed.jpg "Kiosk activation failed")[](https:2019/01/Kiosk-activation-failed.jpg)

- Alternatively, you can also give ‘All Files Access’ for the Hexnode UEM app from the device settings page.
