Hi
I'm trying to embed a generic Android tablet (4.4) into a console. Since it's physical power button is on its side and this area won't be accessible I need to find a different method to power on / off the device and provide the power button functionality from outside.
I initially thought about installing an outer button, disassemble the tablet, and solder the wires instead of the current button but there must be a different option.
The tablet has its usb socket. Is there a way to utilize that in order to connect a button through USB and using it?

to bring all android tablets to recovery mode, there are some buttons like power+volume keys or home and etc, but this tablet, Kouziro FT103, 21.5 inch, has only power button, usb ports, mini usb port, HDMI port and mini-sd card port,only these!
how can I bring it to recovery mode to reset this tablet?

I've got a Chinese tablet that boots properly up to the unlock screen, where if I'm quick I can unlock, I can see wifi is connected, etc. but around that point it completely freeze, even the power button doesn't turn off the creen and I have to reset it by long pressing the power button.
I tried all combinations of keys to bring up a recovery (power + volumes) without luck so far. If I press any volume or back key while powering up, the tablet doesn't power up and stays black. adb isn't finding the tablet. I opened the tablet, there are pins to connect a rx/tx serial. I could do connect a serial adapter to it if that could be of any help.
Actually, at this point I don't care much about the tablet but that could be a good opportunity to start learning a bit more about Android hardware development, just don't know exactly where to start.
Any tip?
We'd like to power up off-the-shelf (rooted?) Android tablets without using the power button. Can it be done externally, through the USB port? We have the tablet connected to a control box that provides charging/running power to the tablet. We want to ONLY have to turn on the control box to get the entire system up and running. Assume battery in tablet is dead, too. Thanks in advance!
My JY HU has no physical clicky buttons, just touch sensitive buttons. On the rare occasions where Android crashes, it needs to be rebooted which cannot be done without turning off the ignition as the front power button just puts it to sleep.
To get around this, I want to install a physical power switch interrupting the accessories / ignition power feed but I've reached a stumbling block as there are different types. Can anyone advise me which type I need to buy? Do I need an SPST switch or SPDT switch?

You need a SPST. Cut the yellow wire fixed 12V. Keep the switch on for normal operation. Turn off momentarily
for reset.

@CARRisma - if you hide the SPST switch, you will gain the added bonus of being able to disable your head unit when you take your vehicle in for any work or when you need to valet park.
Here's a link to a good switch to hide that I've used on many installs:

Yes, that's exactly what I'm thinking too. I've bought this one:-

When plugged in it shows the battery percentage at 99% but I can't seem to get it to power on via the power button.
If you can't find a button remapping app that will allow you to use a volume button to turn it on, plugging it into a pc usb port turns it on. The power button ribbon might not actually be damaged. It could have either slid out of position, or that area could just need cleaned. Its not overly complicated to open it up
