Note 10+ making clicky noise when space bar back and home button pressed

[wawa24]

I have noticed tonight when I press the space bar and the back home buttons my phone makes a clicky noise.. and when I get a message the vibrate has changed I wonder if something is loose and if its going to be a major problem? 

Thanks

You've got keypress sounds on in the settings.

Go to - Settings- sounds and vibration - system sounds and vibration and there you can turn off the key sounds (which is the clicking you hear).

I usually have the sound of my keyboard on. I have tried turning my phone on to landscape and its doing the same as I originally thought if I have dropped my phone and caused this.. but when I get a notification the vibrate noise has changed. its much more faint now but then it sounds like a rattle vibrate noise.
