S7800 is the first JXD’s model features a Rockchip RK3188 ARM Cortex-A9 quad-core processor, 2GB of RAM, 8GB of storage, and a 5000mAh battery.
It comes with front and rear cameras, stereo speakers, HDMI port and a series of buttons (dual analog joysticks, a set of four navigation keys on the right and four-way controller on the left, two analog triggers and two shoulder buttons )—all are designed for gaming. The touch panel smacked in between the buttons. Although many Android games are designed for touchscreen controls — and you can us the 7 inch touchscreen to play if you’d like. Games that support physical controls, however, you can use the D-pad, analog sticks, shoulder buttons, and others.

Unfortunately, in the few days’ review, the feelings of touch is not so good—I must press heavily when opening apps. And the screen is not sensitive when gaming. Maybe, the physical buttons compensate for the touch panel.
PERFORMANCE
It features a 7-inch IPS with a gorgeous resolution of 1280*800 and provides large viewing angles, saturated colors. The pixel density reaches 216PPI.

Game
It is a gamepad more than a tablet. Testing out the S7800 with a handful of games that include such as Shadowgun, Asphalt, NBA 2K13, Samurai2( all are run smoothly on S7800). Instead of using those pesky touch controls, S7800 frees things up – giving me enough real estate to enjoy the action on display.
For first person shooters, I am able to rely on the dual-analog sticks for precise controls. The delay between inputs on the gamepad to the actions performed in the game were nonexistent as every input resulted in an immediate response. Even better, the various main buttons, shoulder buttons, and analog triggers help to make it simple to operate. In short, FPS benefits a lot from the S7800.

It is pleasant when I playing racing games on S7800. Moving around the sticks, frankly, feels better than touching on the screen. Also, I can see the whole picture instead of blocked by fingers.

JXD also points out that the tablet can run a series of emulators that let you play classic games for the PS1, Gameboy, and other consoles. And I have tested the classic game that once popular on PSP—Street Fighter

CONCLUSION
Frankly, it is more like a PSP that shipped with Android, and it can run most games smoothly. If you love playing games,but annoyed by the way of control, maybe, S7800 is a good choice.
