My wife has a Google Nexus 4. Guess what, there isn't a native call recorder on that either. I'm not sure what difference it makes whether or not it matters an app is from MS or not. There are SEVERAL timer + stopwatch apps. There are also some folder lock apps and gallery lock apps. On the Google Nexus 4, there isn't a native gallery lock either.
Maybe there are "missing" features on WP8, but there is an app store you can use to find apps for these functions. I really don't understand these types of threads. Other than the call recorder, there are apps for the other mentioned "features." What's the big deal?
