Thanks everybody about this! I happened to solve this problem( it's not really a bug). If you are one of those people out there who have the same problem, here's how to solve it. So if you have this problem, go to settings, go to keyboards( or search ' keyboard' on settings) and see your keyboards. If you have G- board, it doesn't work. So you either delete it, or keep it. There's this other way ( that sometimes doesn't work) there should be.a thing that looks like an old-fashioned caculator and tap on it. That's how you should solve the problem. Since I ( we) solved the problem, this topic will just.be a place to discuss your projects and the bugs you encounter. THANK YOU EVERYBODY.
