This feature has been driving me nuts. Everytime the phone receives some sort of impact, from a slight shake to a 1ft+ drop, the google voice search activates, each time interrupting whatever it is that I'm doing. I can be biking with the phone in my pocket whilst listening to music, and the voice search will trigger from the vibrations. I stood at a bus station last week and 5 18-wheelers rolled on by and apparently the sound of the engines alone made it impossible for me to use my phone for an entire minute as everytime I would press back, voice search would be triggered again. I have tried disabling google search, I have tried scrolling at the bottom of the apps list and disabling voice search, I have tried unchecking google voice typing, I have tried disabling hotword detection. I factory reset my phone this morning hoping it would solve the problem, to no avail. I have an otterbox case if that matters. How do I get rid of this?
