As a basic privacy concern, what permissions your phone’s apps have is a pretty important one. More recent versions of Android (6.x and up) let you control what your apps can access. Here’s how it works.
Back in the old days—we’re talking Android Lollipop (5.x) and below here—you basically had two choices when it came to Android permissions: accept all permissions an app requested, or don’t use the app. It was that simple. Regardless of whether or not there was a good reason for an app needing access to a specific permission, it wasn’t something you had much control over.
