Hello forum,
Okay, solved this OP upon thinking.
The OP answer is just "any" of many "launchers" for the android touch phone interaction *interface"
that obfuscate the device.
There are many launchers that don't reveal aspects of the device. Familiarity will likely see device users that simply just use "as is"....... the device.
These launcher interfaces are free & designed specifically for non-holistic interacting. Just one dimensional User focused. ("as is"----device)
"Text launcher" is such or "ap15" ....and one "hides" any pathways to system underlying's (settings)
(non required app interacting)......"play store"
1) minimalistic obfuscating Launchers.
https://play.google.com/store/search?q=text%20launcher&c=a2) also pinning an app to the screen......screen can't CHANGE at all....without the PIN CODE to unpin
(any droid above ver 5.0)
Human Computer Interface (design) HCI
thx
