I have an android device that has no battery/accu. It gets powered by poe
There is a button on the side of the device to turn the device OFF (and ON)
However in my project I need to turn the device OFF by cutting (removing) the power.
How can I make the device immune to power failure/writing errors. What can I do to prevent disk failures ?
Is there any option similar to Linux (readonly root with overlayFS or livesystem) ?
