My Samsung Galaxy S5 received the Marshmallow update (6.0.1) and Build number MMB29M.G900VVRU2DPF4 and Message (Version 6.3.3), the phone does not vibrate for incoming text messages. When I go into the sound menu (either through theside volume buttons or under Settings> Sound and notifications, the Notifications and System volume control options are grayed out. Also under Sound and notification the Vibrate when ringing option is checkmarked and green but also grayed out. I have been onmultiple websites and forums researching this proble, checked setting inside of the app, system, and sound and am still having this issue. I have also cleared the cache from the recovery menu as well. Is there a resolution to this issue? I have missed multiple messages and notifications due to this "glitch"!
