I have a Xiaomi phone. The hardware is pretty nice and I enjoy using it. But I don't trust it and find it creepy as hell.
The built-in file browser shows ads related to random conversations I've had(not related to searches or my general interests) way to often for me to consider it a coincidence.
I'm seriously considering getting an iphone again, just because I trust Apple a bit more(and only a little).
But there would be no way in hell I would do sensitive work on Huawei or Xiaomi laptop.
