I’m old enough to remember those Black Flag commercials from the early ’80s with the slogan “Roaches check in, but they don’t check out.” Today, the smartphone variation of that could be “Apps get installed but don’t get uninstalled.”

While unwanted apps may not be as disturbing as unwanted cockroaches, they can be more harmful by not only taking up precious storage space but by impacting performance, reliability and – potentially – your phone’s security.
