Accelerometer and a G-Sensor typically refer to the same thingJust looking at hardware specifications, the two platforms are very similar. However, ZT180's software implementation is way behind that of Telechips TCC8902 in the E7002. You can treat the E7002 as an Augen Gentouch really just from the specifications, except that since it is in an Apad shell, it has a lack of buttons. The news on the market right now is that no Telechips TCC8902 devices have the g-sensor working properly. I've seen of the E7002 operating show the screen rotating the wrong way.
