cursor problem

 I thought there is some staffs for my language because your website's beggining page is written in my language. I can not fluently speak English very well but I would try my best for your understanding. Hope you mind that please.

 I recently downloaded and used your application(Teamviewer) in mobile. And I found that the visible cursor is created on my cell phone's monitor like the way laptop do. I regard it would be disappeared as I delete the app yet it didn't. I wonder how should I do to eliminate this tiny white circle cursor? For your convenient processing, I add my phone model number is TG-L800S.
