Hi I have had the same problem since I got my phone, it's a LG thinQ 35. My husband and son have the same exact phone and all got them the same time but mine is the only one that has had this issue. I have my phone paired to listen to music in my car and it will shut itself off once before I even get out of my neighborhood and again just down the street from my house. It's is super annoying so if anyone had found an answer why and how to fix it I would be very appreciative! Thanks!
