This is the problem not only with Lenovo. Many mobile apps try to collect as many information as possible (for example, GPS location or WiFi station ids) and save to their servers. There should be a law explicitly forbidding secret collection of information especially if it is not required for app functioning. I also remember similar case when chinese smartphone manufacturers preinstalled adware on the devices. It was showing ads above browser window to make it look as if it was a part of a webpage (and used Google ads by the way).
