Bought last year this device and started to use it. In General froze up, but occasionally. Camera the tablet standard. I rarely talk on the phone, so use the tablet as a phone and as a mob. device to be constantly connected.
When there was no Internet, used the tablet as a hotspot to access the Internet. It must be said, very convenient.
Of the shortcomings - awkward system for getting screen captures. Prihodite PTS long press on the power button.
But the essence of what is. This summer I have overheated the children too long raped him. And tablet no longer included. After lying some time, about 2 months, he is unexpectedly raised) it Was for me very pleasant and unexpected event. Yes, now also sometimes freezes, but it WORKS. And this in my opinion is the most important!
Used a couple of times a gps navigation is also a handy thing in a way. Don't need a machine Navigator)
To change the device is not going to!
