I don't see the point of this one for that price when the M10 Tab Plus 3 Gen with much better screen better battery, pen support is available for 190s euros.
Glad that you called out the sorry state of Android support on Lenovo devices.
I know this is a late post, but the main issue of the M10 3rd Gen is that the display seems to have hardware oversharpening applied. While this is great for text, skin will look quite unpleasant.
I've shown it to several people and most of them confirmed that textures seem over-enhanced.
I wouldn't recommend it for photo viewing
