How do you check if android phone has a virus?

I was just playing a new game on my phone, one of those clickbait addictive games, my screen suddenly went white with loads of text and a countdown saying my bank details will be leaked when the countdown ends. Im not really freaked out because my phone is new and I dont have any information on it yet, I deleted the app and ran a Google play protect thing and it said everything's fine? Did I just accidentally press a dodgy app or something?
