IM使用Samsung J3 2016使用Android 7.1.1抱歉，如果我有错误，我使用手机。
I was looking in settings, and I saw a weird setting option. In "sounds and vibrations " under settings there something know as
Play a sound when certain items are touched on the screen
Now my question is, how is this useful, what is this, and what items triger this sound?
Im using a Samsung J3 2016 with android 7.1.1
Sorry if I have mistakes, im using mobile.
This option serves as sound feedback when tapping on your screen, for instance on your keyboard, or (usually) when navigating menus/options in the Settings app.
(My opinion : while useful, be wary of not activating that option in public places/transports, as it's usually very irritating for other people to hear your tapping feedback)
