So now to the actual device. I do not want to mention again all the previous speakers have already written everything here. I can only agree with that actually. In my Android 4.4.4 was already on it.
I think for the price you get a very good piece of hardware that is very well protected with Gorilla Glass, and on top of that has the latest system version. The update on Lollipop announced whether it will have to see.
For me, a strong buy recommendation !!!
