No Android 10 on mine here in Canada w/rumors stating Q2 2020 buuuut... considering mine has only received a single update (January's security patch) since purchasing at launch wouldn't hold my breath on this one. And LG is keeping pretty tight lipped on the subject of support as I've only gotten song and dances when they reply back to my questions on these subjects.
In my opinion it's a great device for the price, nope by no means perfect yet very capable and that DualScreen add considerable functionality if utilized. In saying that though, support (as already mention) isn't looking good not at all. Been just 6+ months sure but a very poor showing out of the gate imo so hard to recommend for that reason alone.
