The Hisense Sero 8 runs Android 4.4 KitKat on a 1.6 GHz Rockchip RK3188T quad-core CPU with 1GB RAM, 16GB Flash storage, a microSD card slot, Wifi, Bluetooth, and a pair of unimpressive cameras.
The 8" screen is based on an IPS display with a screen resolution of 1280 x 800, and it has a cheaper 5 point capacitive touchscreen.
So far as I can tell no one has put their hands on it yet so it's not possible to draw any conclusions about the tablet, but if I were to hazard a guess I think the Sero 8 is probably going to have a cheaper build quality than the Sero 7 Pro.
The Sero 7 Pro had a more expensive CPU and better cameras than the Sero 8, suggesting that Hisense is going for a cheaper market segment. The VGA and 2MP cameras on the Sero 8 make me think of the bottom of the market tablets found at $99 price point last year, and not the better quality Hisense Sero 7 Pro, which retailed for $149.
In any case, I am expecting to see this tablet released in the US in the next couple months. I am looking forward to the reviews.
