How to disable the "waterdrop sound" played when locking or unlocking the screen I am running Android KitKat 4.4.2 on a Samsung Galaxy SIII Neo. I have installed the Screen Lock Pro app which allows you to log off by clicking a home screen icon or tapping on a notification drawer entry.

Now I would like to know whether I can leave the sound volume on, but disable the sound that is emitted when the user logs out / logs in.

I presume this can be done by renaming a sound file somewhere using a similar trick as can be done with the camera app.

Thank you for your replies.



NOTE: This question I am asking is the same as this one for Windows 7 PCs, but relates to Android devices instead.
You don't need to edit any sound files as the Screen Lock app has provided this as an inbuilt feature to disable/modify lock and unlock screen sounds.

Open Screen Lock app and open Settings, scroll down to the bottom and you will be able to find the option to uncheck and turn off the sound when locking and unlocking the screen using the widget or notification bar.
