Android 7 Developer Preview 5 just hit the interweb and one new addition is application source indicator. The app info page now has an option right at the bottom that will show you if the app was installed from the Play Store or sideloaded using an APK. We have to admit, it's not a hugely useful feature, at least not to most users, but it's a small bit of additional info that is now available should you wish to know. Via
