The ZTE Blade A2 was launched back in June last year. It came with Android 5.1 Lollipop-based MiFavor 3.2 out of the box. However, now it looks like the device will get the Marshmallow update soon, as an Android 6.0-powered Blade A2 has been spotted on GFXBench.
Sadly, there's currently no information on when exactly the update will be rolled out, but given that it has started appearing in benchmarks, it'd be reasonable to say that the roll out shouldn't be too far away.
I bought in China and sold one month later. Decent phone for the price but I just can't simply freakly use it.
Correct my friend, I just bought a Cubot note s with marshmellow out of the box, duel sim and 4, 150mah battery and love it, all for £68,puts my old note 3 to shame, Chinese the way to go :-)
Most good-looking phones are from China.
