I got this to automatically raise the volume for my car's Bluetooth without having to endure the volume warning from the system. Occasionally it only raises it to the pre-warning volume, meaning I still need to turn it all the way up manually.
Great for car / headphone pairing. Also reads text messages as speech
Connected BlackBerry DTEK 50 to BMW 2002 E46 Car Bluetooth.
Has no effect on volume on Pixel/Nougat. When enabled, the notification pops up alerting the connection - and prevents MusicBoss from automatically opening on my Pebble. Either way, regardless of settings chosen, it's clearly running yet volume is back at 50% every time I connect.
Should be basic Android functionality Now when bluetooth connects to my car I can hear it without fiddling with the volume and accepting the silly message, for the thousandth time, about loud volumes being dangerous for headphone use.
Excellent app that works very well. Totally free with no ads. Running Moto G3 with marshmallow 6.0 this app works very well. It has separate volume presets for media, alarm, notif, and call. It toggles the volumes when the Bluetooth is connected or disconnected to allow you to have special settings to work with your device and return to normal status afterwards. This helped me to improve weak call volume settings in my speakerphone . As a bonus this app even turns on Pandora. Note that this is not a volume booster. It can only go to max volume. It can't go to 11.
