I have some bluetooth speakers that works fine with every other phones but when I connect my fairphone2 on it for music, the maximum volume is very very low.
I’ve tried to connect the phone to the speaker with a jack-cable but the music isn’t louder.
I’ve seen on other posts (this one) that some volume parameters can be set differently through engineer mode, but i can’t access the topic yet. Is it possible to know how I could change the maximum volume setup?
Thanks for your help!
