Hi, i have an issue with display backlight on my F7PROs. It occasionally stops working and after some time starts back on working again.
I havent figure out any dependencies why does this happen. Once in a while it just stops working and it is not possible to trigger the backlight on (not by pushing the button nor touch the screen nor hand gesture). After some time (few hours to several days) it just starts working again. Its happening among several fw updates, soft and hard resets, all related system settings checked. I have no other issues with this particular device.
Any suggestions how to deal with that? Or is it a clear HW issue?
