Has anyone else noted that their main button underneath the screen on front is losing its 'click'? Mine is sort of squishy now and there is almost no 'click' feel when pushing it so that I know I have. Am sure it will be a warranty-covered item but hate to go through fully restoring all the settings on my Note 4 (but also not willing to root and Titanium etc.) Juts wondering if anyone else is experiencing this? Given that my USB connector is kind of losse-fitting now too it might be time for a refurb replacement from VZW....
