Today at S7 Fan Club, we are coming up with an excellent guide for Rooted Galaxy S7 SM-G930F and Galaxy S7 Edge SM-G935F, which enables the function of Dual Speakers for Music on your Galaxy S7 or Galaxy S7 Edge smartphone. This mod basically enhances the volume of call speaker and it feels like a surround sound. Dual Stereo Speakers will work and you will feel huge difference in earphones volume.
