Reading many of the post on various threads - you guys are far more advanced in usage on Android that I am with my very limited VM phone. The VM phone had limited space so I don't know all of the apps/tricks. I do not plan on rooting my N5. With that in mind, if you can suggest some apps that are "must have" for utilities/programs (briefly why it is a "must") and other cool apps to take full advantage of the N5. Thanks!
