Like Carslog went Chinese a 4 months ago with a Blackview, BV7000 model, as I keep smashing phones and it was getting both irritating and expensive.
Seems to work just fine and for the features, 3/4/5G, dual sim, Gorilla glass, IP68 rating, , dual GPS, long battery life, 64GB memory etc it was very cheap compared with the equivalent Samsungs.
Build and reliability seem good for the price, around 150GBP in this case.
