Supplier don't answer to me now. I bought 4pcs.External all is good, logo with android placed in back side, metal back side. USB-host is not work, can use only mouse, but don't see any another device - usb-flash (5pcs), hdd, cardreaders...G-sensor also work not correctly, absolute impossible to play in games. Low volume of sound. All other parts worked is well ( wi-fi, as example ), I installed last custom firmware Hibryd 6(beta) - same problems with hardware ((( How I can repair this? Maybe I can buy new IC g-sensor. For this a have question too - in China price of this IC is about 4-5RMB, but in Russia - about 9$ ! why so big differents?And I don't understand, why mouse is worked, but flash-usb not worked (I need help, please...)Oh, yes, about "iRobot"(fake) - LED is orange. USB-hots socket in up, control USB in down.
