I'm running 1.0.6 apparently. It simply didn't occur to me to update it, since it's not connected to the internet and worked fine out of the box for me.
I'd consider the performance quite good given the low price. Sure there are faster printers out there, but with the default profile in orca slicer it can do a benchy in ~50 minutes which is good enough for me. And quality wise the prints seem to be on par with what other people are producing with much more expensive printers.
What's missing are some comfort features: no runout sensor, no failed print detection and no network connectivity mean that printing is a relatively manual process and it's "risky" to do long prints unsupervised, because this thing will happily produce spaghetti until the gcode is done.
On Android it likely will, I have done exactly that before. Kinda looks weird to see a ethernet symbol where the WiFi icon usually is
