Randomly works...or not I had an S5 and it worked flawlessly. Since upgrading to an S6 and now S7  it sometimes works and yet maybe it won't. Bottom line...I can no longer trust it to turn ringer off automatically and still have to check manually. I thought the new smart manager might be disabing the app  so turned it off for the app and then off altogether (for all apps)  to no avail. It's unfortunate because this app used to be perfect.
