放大锁定屏幕上的文本 -- lock-screens 领域 和 fonts 领域 android 相关 的问题

Is there a way of enlarging the text displayed on the lock screen? Specifically, I want to enlarge my music player's "notification" to see what track is playing and its info (I use Poweramp).

I tried an app called "Big Notifications", but it doesn't do what I want (it makes them bigger, but only on the Notification Area of the status bar). I would like to increase the size and visibility of the text on the notifications that appear when the phone is locked.

Thanks!
