Samsung Galaxy Note Edge clearly does not have an edge when it comes with speaker sound quality. Fortunately XDA has made a surround sound patch that improves speaker sound quality to some extent. This mod will activate your earpiece speaker along with rear main speaker for playing music, watching movies, shows, you tube and so on – creating an illusion of surround sound effect.
This surround sound patch modifies the mixer_path.xml file in you system/etc folder. You are a rooted Galaxy Note Edge with clockwork mod recovery or TWRP installed. Here are the steps you need to follow:
1. Download the MOD from here and place them into the root of your Samsung Galaxy Note Edge android phone.
2. Boot into recovery by holding and pressing the Volume Up + home button.
3. Navigate to the file placed earlier in step 1 and press power button to flash it. Wipe Dalvik Cache ONLY. Now wipe Cache ONLY. Now wipe both Dalvik Cache and Cache. If this worked for you, you will now be able to wipe caches without mounting errors. Begin from scratch and re-root your phone.
