Hello, I'm trying to find out, if there's any possible way to control and increase the Facebook Messenger's (FM) in-call volume, with connected headphones (to Asus Zenfone 2 500cl, which I guess is not really important). Besides FM, playing media files, and in-call volume in calls with other applications are loud enough. Does the FM limit the volume itself to a particular level? If yes, is there any option how to change it?
Thank you
Thank you
