Spacebar not working for junping

When i connect keyboard and mouse to my phone everything works normally. But when I use spacebar for jumping it just stops working. When I try to open chat and talk it does work but in-game not. Other than that I can't bind my spacebar in settings. And I have bought 2 new keyboards so it isn't an issue with that. I don't know why it stops but I have to use another key to jump.
