Don't buy any Blackview phone. It is a scam, they will make a full of you. Why. I have bought a Blackview bv8000 pro. It was the best mobile phone I ever had. But it come a softwer update, first, second, third... and no problem with updates. And than - last update - the lock pattern just stop to work. It show "wrong pattern". Ok, I start to google and I found a blackview forum with a bunch of BW owners that have the same problem, more even the owners that used pin protection had the same problem "wrong pin". The Blackview answered that they are familiar with problem and it will be resolved soon. I wanted to write that I have the same problem but after all writting I had to write captcha (6 numbers) to show that I am not a robot. But there way no place where to write it. Since that, 4 mont have pased and there is no fix. Second problem - after last softer updste the phone became slower at least 5 times. Yes, 5 times, no exaggerating. I have decited to do full factory reset. I did it but it is still 5 times slower, every 1 to 2 minites it frezzes totally for 10 -20 second and you can do nothind but to look in screen. The phone is now totally uselles.
