On my rooted Nexus 6p with Nougat 7.1.1 it solves the most annoying problem in my first world cupboard of problems - my volume was being reset to 50% every time I connected to a bluetooth media device. This app solves that be automatically raising the volume.
This seems almost perfect for me. Using the "voice call stream" it interrupts the radio (Ford Sync) as a hands free call and reads the text/message, so no missing them when I am not listening to the "aux" mode of the radio where the "music stream" is usually heard. The only problem I have is that the "call" sometimes does not end after reading the message. I have to manually "hang up" (not the end of the world!). Great app though. Thank you.
This APP is exactly what I have needed since owning my android phone. It was soooooo annoying having to adjust my volume when getting into my car, especially if my phone was in my bag. Epic app!
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.
Exactly what I needed for my Moto G4 Play running 6.0.1 and connecting to a Bluetooth to FM converter. Now the volume is at Max when it connects like it should be instead of about 70% volume. Thank you so much to the developer.
Tried a bunch of BT volume controls but this one is the best! Individual device control is very important when you have alot of devices.

Auto Bluetooth will enable Bluetooth on an incoming call and stop it afterwards
