Phones posessed ?

[AC Question]

Hey smart people, can somebody help me out ? Ive had my s6 edge + for little over a year now. In the time period, it has made a noise, * similar to an old creepy door opening, like in a scary movie *, a few times. Notbsure what it was. But now, i closed out of my Gmail app, & a weird guys voice, * described like steven hawkings / the talk voice thing on computers you used to play with in school * , i read a similar article about a guys wifes phone doing it, but talking about cars & driving. I couldnt tell what mine said, but i know it wasnt like maps or whatever. Any ideas guys? ( my phone has no voice thingies on/enabled, again, its never made that one before ).
