Fix on the screen the controls

Hi everyone, I’m making a platformer game for Android. But I have a problem, I can’t fix the touch controls on the screen. Even using the anchor functionality doesn’t work. I did a test level and tried to create a test game and tried to click the button to manage the character but as soon as the character moved on the controls would pop out of the screen. How can I solve the problem?

Put your control buttons on another layer, so they won’t move with the camera
