The development was very successful and gave rise to TeamViewer GmbH, which today operates as TeamViewer Germany GmbH and is part of TeamViewer AG. The IT service provider wanted to avoid unnecessary trips to customers and perform tasks such as installing software remotely.

Rossmanith GmbH released the first version of TeamViewer software in 2005, at that time still based on the VNC project. TeamViewer is the core product of developer TeamViewer AG. It has been installed on more than two billion devices. TeamViewer is proprietary software, but does not require registration and is free of charge for non-commercial use.

It was first released in 2005, and its functionality has expanded step by step. TeamViewer is a remote access and remote control computer software, allowing maintenance of computers and other devices. Windows, macOS, Linux, Android, iOS/ iPadOS The idea seams to be that the user of the iPhone controles the iPhone locally as usual, but another person can watch from remote what is displayed on the iPhone - and give advice by telephone or another chat-tool, but in any way NOT controlling the iPhone remotely.15.29.4 / 26 April 2022 6 months ago ( ) ġ5.29.96 / 26 April 2022 6 months ago ( ) ġ5.29.1 / 4 May 2022 5 months ago ( ) In the picture you supplied you can see that the actual screen of the iPhone is displayed on your PC - so it works.

The message „Dieses Gerät kann aufgrund von Firmware-Einschränkungen nicht gesteuert werden“ is correct: you cannot control the iPhone from your PC - thats it. Depending on the settings it changes within 30 seconds to standby. The other point was that according to the product description no remote action is possible: no clicks in my PC-Teamviewer will be transported to the iPhone and therefore the energy-saving count-down on the iPhone is not interrupted. So I propose for further tests to disable all energy-saving options and take care that the iPhone screen is illuminated. I guess, the reason was that during the operation to connect to the iPhone, the energy settings caused in the meantime a change to standby-mode which, in turn, cuts the connection.
