Dual front- facing speaker on your phone will give a whole new audio experience while listening music, watching videos and playing games, but unfortunately, only a few well-made smartphone manufactures, such as HTC, Motorola and Sony are making dual speakerphones. LG Nexus 5X has dual front-facing speakers on it, but one is used for audio and other one is used as earpiece.
You can activate both speakers on your Nexus 5X for better audio experience. The ‘Surround sound’ mod for Nexus 5X activates both speakers on your phone while listening music watching videos and playing games. Note that this mode will not give the same experience as a dual speakerphone gives, but you will definitely have a good audio experience.
Just like any mode, the Surround sound mod has also required a rooted phone. You can install the mode in a couple of ways, either by manually pushing the required files to system/etc and set permissions to rw r r, or just flashing the zip files via custom recovery.
This guide is going to assume that you are already pretty savvy with tweaking Android OS and that you have got TWRP installed on your Nexus 5X and root access.
