I have a Samsung Galaxy P610 Tab S6 Lite and when I reboot it (via Android option or reset keys - Power + Volume Down) it does not power back up.
It can take hours to days where whatever is the issue discharges or clears and the device will power back up. The screen is black when it is malfunctioning and with the USB power connected or not the device will not respond. A reset via Power + Volume Down will not bring the device back up until a discharge or clear (or whatever is causing this issue) occurs internally. Eventually if I connect USB power and when pressing the Power button I see the battery status on the screen (as it should do when the device is powered down). At this point I know the device will power back up.
This is a known problem on the Internet for this device. (On guy on the Internet was going to turn his device into an expensive cutting board and then his device suddenly starting powering up - similar to what I have described.) Some have blamed it on a firmware crash. I am current on firmware.
I have had both Samsung and Asurion look at the device and they have determined nothing is wrong.
The best solution I have come up with is to install a reset button for the battery ground connection that would allow me to "disconnect" the battery in order to return the device to functionality.
Does anyone know of someone who would be willing to consider adding a reset button like this that would allow me to disconnect the battery when needed?
