Hello, 

There is a annoying bug in minecraft beta when using the keyboard and mouse in Android, Shift+Space and Ctrl+Space does not let you run and jump when the spacebar is released. Instead you just stop in place and have to press the keyboard combination again. 

This bug might be interfering with the keyboard shortcut of Samsung's "Change language input" keyboard shortcut.

But I tried turning the shortcut off, yet the bug still exists.

I'm running on Android 11 with a Samsung S20+ phone.
