Well the good news is that there is a mod out there that will help rectify the situation, and in some cases could give you an “almost surround” sound experience. Basically what the mod does is that it activates the front earpiece of the Galaxy Note Edge to allow it to be used as a secondary speaker for the phone.
However it seems that this mod is only applicable to the Galaxy Note Edge and not the Galaxy Note 4 at this point in time, although it is unclear if the mod will ever make its way onto the Galaxy Note 4. While we have yet to try this mod out for ourselves, its creator sshafranko has described the effect as an “almost surround sound type of effect”.
There are three different variations that users can choose from regarding its volume, ranging from a default volume level all the way until a high volume level. For those who are interested in checking out this mod, you can head on over to the XDA Developer forums for the details. It should be noted that it also requires users to have a rooted Galaxy Note Edge.
