What is the problem on JXD S5110's joystick? The joystick is not ture. It is connected with D-pad not seperated. For the WiFi, I think it is OK. You can connect it well.
I think JXD S5110 has a better d-pad and buttons controls on gaming comparing with Droid x360. But Droid x360 got a better screen.
Both of them can support the main emulator such as PSX, NES, GBA ect.
