Power button issues reported above should be solved on version 24.04beta14.
Now after shutdown via menu, to turn it on again, for all devices, it's only necessary to hold power button for 1 second.
Yup. That solved it for me.
I own 2 Amigos. One of them has this weird power bug & one doesn't. When powering on the Amigo that DOES have this bug, the device always does a strange flash of light from the back (is that a flashlight below the rear camera, or is it just a bright LED?). It used to flash a blip of white light, and then nothing. Now, with your fix, it flashes with a blip of white light from the rear of the device, and then powers on. When powering on my other Amigo which DOESN'T have this bug, it just powers up - there's no flash/blip of white light from the back of the device.
Oh, and nice, you've added a screensaver since I last updated (or maybe I just haven't left my Amigo running idle). It's been sitting on my desk as I type this, and the screensaver just came on. Well done. The option to Wipe Device is a nice addition too.
You're doing such great work. Krux is fantastic.
