m-sat Skype did not check, not installed. But it should work, it's obvious. Why then the front camera and microphone? In general, I like the tablet more and more. I installed SPB Shell, the desktop became comfortable, everything flies, and the connection is amazing, that 3G, that Wi-Fi. Funly opens autocad files. The screen is good, but immediately I advise you to remove the factory film, it is very thick, with it there is no sensitivity. Pleased with the speakers, the sound is very decent. The USB sockets are inconveniently made, under a hard-to-open lid, I think this is protection against splashes and dust (where are we just not using our devices). And the ON button is inconveniently located, if you buy a third-party cover, you need to watch so that the mount does not press this button, otherwise the tablet will constantly turn on itself.
