No, there's no way that you can recover your bitcoin though, since you have lost your phone already. It's hard to guess what phrase are you missing.
In any case, I feel sad and dishearten to hear you lost 19
BTC in an instant. Not to rub it in, I myself lost early but I can't do anything about it so I just move on in my life and treat it as a expensive lessons to learn in crypto sphere.
And unfortunately that is the only thing that can be done right now, he needs to move on with his life, I know that my life would be way easier if I had 19 bitcoins in my wallet and this is probably the very same thing for the one that created the thread but he is never going to recover those coins, I know it is painful to hear and it is something that he probably doesn't want to hear but it's the truth, anyone offering the possibility of recovering those coins is probably thinking about scamming him.
