I have a moto G 3rd gen, with Android 6.0 my Bluetooth devices are all very low in sound. It's extremely hard to hear. I Have tried several sound booster apps. They do nothing. Most just give me another way to move my volume rocker. Being able to hear is crucial to a phone. I'm at a loss on what to do next. Please help. devices are... headsets (2), 2015 Chevy vehicle.
