Open Developer Options Tab on Sonim XP5 XP5s or XP3

Open Developer Options on your D-pad devices to enable a Vysor connection, to sideload, and to send bug reports.  Since there is no touchscreen display available on the Sonim XP5 or XP5s, you cannot use the shortcut to open the Developer Options.  Instead you must use the telephone, and dial: *#*#2387#*#*

The device will then open the Developer Options tab. Ensure the "Take bug report" option is enabled, and that USB debugging is also enabled.

You may also add a menu button to the Power tab for future access to this feature.

Other Sonim devices allow access to Developer Options via the settings menu, reached via the device's soft keys.
