Tablet settings
Your tablet has several power saving features which causes the screen to dim or switch off. To prevent this,
- Deactivate the Adaptive brightness feature to control the screen brightness yourself.
- Settings > Display > Adaptive brightness
- Increase the screen timeout.
- Settings > Display > Screen timeout > 10 minutes
- Enable "Stay Awake" while charging mode.
- Settings > About Tablet > Software Information
- Tap the Build Number 7 times in a row until you see the message "Developer mode has been turned on."
- Go back to the main Settings menu and select Developer options (at the very bottom).
- Find the Stay awake toggle and turn it on
