Using KB+M on Android, mouse doesn't work

I can not move the camera using the mouse, only the keyboard works and not my mouse has no defect, i enter the game to try to use the keyboard and mouse, but when i inter i realize that it is not working after i inter my world, but still the same bug, this is really annoying because this bug is a long time in the game, i want to play using keyboard and mouse because it has an option within the game, i hope you solve this as soon as possible.
