I'm using Moto E 1st gen. on Android KitKat. I'm used to listening to FM radio while travelling, but whenever I want to tune-in to other radio station, I have to unlock the phone first because I'm using a pattern lock. I'm also using headset, but there's no control buttons, so I can't change the radio station with it.
Since it's difficult to unlock while travelling (moving) and sometimes takes too many attempts, is it possible to tune-in to next radio station without unlocking? Perhaps a widget on the lock-screen?
