Based on their selling price. So far, Huawei have exclusively put VH in "flagship" phones, based (only) on the Kirin-960 chipset. The cheapest VH phone have probably been the Honor 9 at about €400.
The phones you mention are in the $140-180 range, well below half the price of the currently cheapest phone Huawei have opted to use VH in.
For their midrange phones with stabilizers, Huawei have instead kept on using Morpho so far (leading me to believe VH gets more paid per unit than Morpho), while phones in the price range you mention here, have not yet had any stabilizer as far as I've seen.
So my guess is that if these run a stabilizer, it is probably Morpho MovieSolid4.
