Low volume after firmware update to 01.02.18

Hello guys, 

back with the original firmware i had the same problem when choosing the Europe region as my location, so i read about changing it to “Rest of the world” which worked fine back with the original firmware.

since i’ve updated my firmware yesterday theres no difference when i’m changing regions, and the far more annoying problem is that even though my region is set to “Rest of the world”, changing the volume from “normal” to “high” doesnt effect anything!

has anyone got a solution? it’s frustrating! i’m not using the device wearing headphones, it’s plugged to my car stereo…
