I'd advise skip Blackshark instead. I too have my hopes to Blackshark since its rumors. And since Xiaomi funds this company, I really wanted to get my hands on this. A cool gaming phone that really performs.
2019 came and there are a quite number of issues people are saying that their Blackshark 2 cannot install pubg, some Blackshark Helo got bug a with a feature. It's like a hit or miss and this is quite dissapointing since this is the first gaming phone that came out and yet their phone suffers hit or miss issues.
