How to disable Easy Voice Recorder from displaying info on locked screen?

[acsurfer]

Hi,

After I press Record on Easy Voice Recorder app, then I leave it in the background running. When I lock the phone, a message displays Easy Voice Recorder appears (see screenshot) on the main locked screen.

How can I prevent/disable the Easy Voice Recorder message?

I do not want any message of Easy Voice Recorder to be displayed.

I am using Samsung Galaxy S4, Android 5.0.1, Easy Voice Recorder 1.8.1

Thanks a lot.
