I have a Moto X (2013), I tried a default thing that the motoX have, the one that discover if you are driving, in a meeting or sleeping. The problem is that it didn't stop the vibrations and sound from other apps like WA or FB, only the calls. Also I would like to be able to choose some contacts in order to bypass this setting, I think it have by default the stared contacts, I am not sure If I can choose those or are based in how often I call them. (Its a new phone, I didn't had time to explore it deep)
