What is the system of mango å—¨Q H2?

This is a screenshot of the machine (it has been upgraded to the official firmware). The original one did not care about what the machine forgot to forget.

A variety of channels to understand, including asking the official after-sales, should be yunos, but the settings can not see the shadow of yunos, after the box upgrade firmware did not have Taobao, etc., this time there is no trick in the yunos event, specially asked after-sales, after-sales Said that this time the deletion of software this machine is not affected, I am a little confused. Is it that the manufacturers took Ali's subsidy but secretly violated the rules and changed Android firmware?
