... We need more footages of fly modes and range and altitude tests

This sounds like a job for Dr Pedantic!
In the US the altitude limit is 400 ft/121.9m and the range is line-of-sight
The Zino is perfectly capable of exceeding both, I'm sure (my H501S certainly is)
The videos I have seen where features on the X-Hubsan app have not worked are usually due do failure to read the instructions beforehand. Many people would like to see features like waypoint, follow-me and point-of-interest demonstrated, it's true. Hubsan has posted videos on YouTube showing many of these functions in just the last 48 hours.
Another channel that does a very good job of testing these functions on production models is Quadcopter101. He avoids testing prototypes for that very reason. In the past he has tested many Hubsan drones and will usually go back and test again if a particular function does not work for him the first time. In any case production models of Zino have yet to be shipped from US warehouses (as of 4pm eastern time Nov. 27) I'm confident Quadcopter101 will demonstrate everything on the Zino once it makes it out to him
