Norton family (latest) is installed on my son's Nokia G400 android phone. I find the time spent on Apps to be grossly misrepresented. For example, the game Call of Duty shows him spending over 2 hours on the device while he was asleep, and I was in possession of his phone and he clearly didn't use it during that time. Another app that shows this problem include Youtube .
This time spent on Apps is shown on Norton's website accessed via a Windows computer, but on my mobile app it shows zero usage for all apps at all time.
