Main Functionality

  • Enable/disable:
    • Screen blanking
    • Secondary display (external monitor)
    • Display of on-screen Lock Override button
    • Resizable and moveable app windows
    • Resizable activity windows
    • Stay Awake mode
    • Screen shot usage
    • Adaptive brightness
    • Automatic screen rotation
  • Set the font size
  • Set the display size
  • Set the screen brightness level
  • Set the display screen timeout interval
  • Set the screen blanking:
    • Signal port
    • Signal polarity
    • Debounce delay
  • When auto-rotation is not used, lock orientation to:
    • Portrait (No rotation)
    • Landscape left (90 degrees)
    • Portrait inverted (180 degrees)
    • Landscape right (270 degrees)
  • When auto-rotation is used, allow orientations:
    • All (0, 90, 180, 270 degrees)
    • All except portrait inverted (180 degrees)
  • Select screen resolution on an external monitor when a device is connected to a workstation cradle

Auto-rotate On/Off

This is the On/Off switch for automatic screen rotation, which automatically rotates the display based on orientation of the device.

Note: On devices running Android 8.x (Oreo), disabling this feature using StageNow causes the device to switch to Landscape mode if Landscape was the selected orientation when Auto-rotate was enabled.

Status: On devices running Android 13 and later, this feature can be accessed through StageNow and compatible EMM systems, or using Android Device Policy Manager (DPM) APIs.

Parm Name: Autorotate

Allowed Orientations

Used to select which screen orientation(s) to allow when auto-rotation is enabled on the device. Selecting "All except portrait inverted (180 degrees)" (option 2) prevents the screen from flipping when momentarily pointing the device downward, for example, to scan a barcode below waist level.

Note: Supported only on devices running Android 10 or later. Android 11 requires MX 11.3 or later.

Shown if: Auto Rotate is set to "Turn On"

Primary Locked Orientation

Used to select the orientation the device should remain in when its screen orientation is locked (i.e. when auto-rotate is turned off).

Note: Supported only on devices running Android 10 or later. Android 11 requires MX 11.3 or later. Some apps that require a particular orientation (e.g. DataWedge, StageNow) override this setting. Opening an app with a default orientation of 'Portrait' causes all other apps to lose any orientation previously configured with this setting. Landscape is the default orientation on tablet devices, and the basis for other orientation references in this parameter.

Lock Override Button Enable/Disable

Controls the on-screen Lock Override button, which (when enabled) allows the device user to override the screen orientation locked by the administrator or an app.

Use Case: When "AutoRotate" is turned off on the device, a "change orientation" button appears briefly whenever the device orientation is changed, allowing the device user to manually override any forced screen orientation. Setting this parameter to "Disable" (option 2) hides that button, removing the ability to override the admin-set screen orientation.

Note: The Lock Override preference on the device can be overridden by the 'full-screen' control found on most media/video players, including VLC and YouTube. Supported only on devices running Android 10 or later. Android 11 requires MX 11.3 or later.

Shown if: Auto Rotate is set to "Turn Off"

Set Screen Timeout Interval

Used to set the length of time the device waits during periods of inactivity (without screen touches or key presses) before turning off the screen to conserve power. Ideally, this interval should represent a balance between battery preservation and user convenience.

Note: Android supports only the display-screen timeout settings shown in the table below. Entering a value between any two supported values changes the setting to the closest supported value. Entered values outside the minimum or maximum shown are ignored and trigger an error in the Result XML document.

Status: On devices running Android 13 and later, this feature can be accessed through StageNow and compatible EMM systems, or using Android Device Policy Manager (DPM) APIs.

Display Size

Used to select the size of UI elements displayed on the device. On devices running Android 13 (or later) with MX 13.5 (or later), this setting also applies to a secondary display connected through a Zebra Workstation Cradle. External monitors are subject to the behaviors listed below.

Devices with Android 13+ and MX 13.5+

  • Settings configured using this parameter are applied immediately on the device. If that device is subsequently placed in a cradle connected to an external monotor, the settings are extended to the monitor.
  • When such a device is removed from the cradle, the monitor's Display Size reverts to the previously configured setting.
  • If a configuration is applied when a device is in a cradle and connected to an external monitor, the Display Size is changed immediately on the device and the monitor.
  • Changes to Display Size through the Android Settings panel temporarily override device and monitor settings previously applied with this parameter; admin-configured settings are restored when the device is removed from the cradle.
  • If a configured Display Size is not supported for the resolution setting of the external monitor, the "LARGEST" Display Size is used, but the configured value is retained internally and considered a custom value.

"Larger" and "Largest" settings are intended for kiosks, tablets and vehicle computers only.

Note: A staging success/failure message sometimes fails to appear on the device when staging increases the display size.
