The Sony Xperia Z is a smartphone for all those who use phones in extreme conditions. It is a water-resistant beauty. While being invulnerable to water is a great quality that all of us might want to have on our phones, it also stems an issue and that is low volume on external speaker. Sony has used very small speakers in its latest flagship and that might also be a reason for the low volume issue.

However, blaming Sony alone for the volume problem will not be justified as most Android devices have it. I have Galaxy S3, S4, Note 2 and HTC One and low volume seems to an universal issue with them all. Keeping the wish of users to have louder volume on their Android phone, we always keep digging for some working solution to increase volume for a range of devices. In the past, we have done some tutorials on boosting speaker volume on Galaxy S3, S4, Note 2 and Nexus 4 and now we bring another volume boost mod that can let Sony Xperia Z users enjoy louder volume on external speaker and headphone.

The Extra Volume Boost mod has been developed by ZeroInfinity from XDA and works of most Sony Xperia phones with Android 4.1 Jelly Bean or above and Qualcomm processor. The volume boost mod has been tested and found working of the following devices:

  • Xperia Z
  • Xperia ZL
  • Xperia SP
  • Xperia T
  • Xperia V

If you have any of the phones listed above with Jelly Bean, you can install the mod via a custom recovery like ClockworkMod or TWRP. Needless to say, the mod only works on Xperia devices with root access.


The volume boost mod for Xperia Z and other devices comes in 3 versions. Download one that corresponds to your device’s ROM. If you want really louder volume, try the super loud mod.

How to Install:

First of all install a root file browser on your phone. Go to System/etc/snd_soc_msm folder and copy “snd_soc_msm_2x_Fusion3” file to your phone’s storage so that you might revert back to original sound effects in case you do not like the volume hack.

  1. Copy the volume boost zip file that you downloaded from above to your phone.
  2. Now turn off the device and boot it into CWM or TWRP Recovery.
  3. Select “install zip from sdcard” or “Install” option (in TWRP).
  4. Select the zip file and confirm installation.
  5. Finally, reboot your phone.
  6. Done!

When your phone boots up, you should feel the difference and louder volume on it. Enjoy!
