Yeah I think the geometry of the original GW charging stand just doesn't work. When I dock the GW3 it works for a few minutes, and then loses contact. I'm able to charge my GW3 with the Samsung charging pad (2018), the duo charger, and of course via PowerShare from my Note 20 Ultra. But not the GW stand. Which is too bad, since it was quite convenient.
Also, why does the GW3 charger not come with an AC adapter? What do you do if you don't have other Samsung accessories laying around? Don't get me wrong, I love the GW3, but this is a minor annoyance.
