The Android GX user interface is missing the upper right hand screen on/off functionality. There does not appear to be a way to turn off the screen using the device. The display timeout settings do something different - they return to home page on timeout and do not set the screen off timeout. Further, the physical tablet device you use also has its own timeout that turns off the screen. Unfortunately, it means you have to mount it with a holder that allows access to the power button to bring it back to life. The OS loaded on the tablet does not appear to have any tablet-specific settings that can be used. Ideally I would like the screen to time out on a setting (ie: 30 seconds, 1 minute), and wake up if you touch the screen, or to immediately turn off if you hit an icon, or tap the upper right area like the touch 70 device has.
Any other suggestions on making this more usable from a timeout and wake-up standpoint?
