Tool tip not gone in mobile when touch on the screen

I used hint with bootstrap dropdown menu and It worked fine in desktop mode , but when I have tested it with my cellphone browser (chrome , safari) or my tablet I see a tool tip still on screen .

scenario : when I press on button(dropdown button or href link which appear bs menu) hint act as a hover and bootstrap menu dropped bythetime I touch on button again bootstrap menu closed but tool tip still on the screen , when I touch on free space on screen the tool tip still alive on screen .
