I am experiencing some kind of "clicking" or maybe "skipping" otherwise somewhat through their haptic feedback (vibration), chiefly visible while typing? In favor of me, it's like if there's static within the vibration, if that makes whichever sense, that apparent as kind of a clicking sound. It's just irritating as much as necessary to trouble me while typing lengthy messages as well as email plus such. If others encompass it and it's "usual," I can reside with it. If it's an indication of upcoming vibration breakdown, in that case I'm going to exchange mine out.
