Screen timeout for AMOLED and OLED displays

Last Updated: 12/12/2016

OEMs can remove the 15 minutes, 30 minutes, and Never options from the Screen times out after dropdown in the Lock screen settings screen.

This is recommended for phones with AMOLED and OLED screens to prevent screen damage.

                         Description="Use to remove the 15 minutes, 30 minutes, and Never options from the screen time-out option in the Lock screen settings screen."

                         OwnerType="OEM"> 
    
      <Static>  
        <Settings Path="LockScreen">  
          <!-- Set the value to 1 or 0x1 to remove the 15 minutes, 30 minutes, and Never options from the lock screen settings screen -->
          <Setting Name="ScreenTimeOut" Value="" />  
        </Settings>

    </ImageCustomizations>
