I’m guessing this is just a white-label tablet being made by a Chinese OEM, and Volla is just adding their software and branding. This looks nearly identical to the Headwolf HPad6, which is on Aliexpress, and I see it for $199 on Walmart.com with 24gb of RAM. Looks identical, and has the same SOC, just has a different screen resolution. Seems like terrible value too. $733 for a G99 SOC. That’s an outdated mid-range chip that comes in very cheap tablets.
From the articles comments, doesn't sound good.
