The remote control panel, which indicates that someone is connected via TeamViewer to the device in question, cannot be prevented from popping up, nor can it be hidden completely.
TeamViewer is quite a powerful tool – it allows you to remote control almost any device as if you were sitting in front of it. That is why security is of the utmost importance for us. We want our users to know when someone establishes a remote connection to their device and we also want them to be able to tell at any given moment whether that someone is still connected or not.
I understand that the remote control panel may sometimes seem redundant to you if you only connect between your own devices. However, please bear in mind that it will also protect you from having to worry about someone connecting to your devices without you knowing it.
I hope this helps.
All the best,
