I am using teamviewer for remote control and my partner using teamviewer quick support. Our androids are connecting properly but i can only see my partners screen. I cant do any changes or any type of click. I can't open any app etc. A cursor is appears. But it not helps me to use my partners mobile phone whicb is Redmi note 4. What is the problem.
