Everything works fine with my OnePlus 6t. I suppose someone would get in touch with me if my phone would not be supported by a certain kind of apps.
Oxygen & Android are both 9.xx.
So I think at one point misinformation came into play here.
Huawei will get trouble, but as stated before, they all come from China. Even Apple & Samsung buy there. Else a S10 would likely be 1500€ and the iPhone maybe 2500€?!
