[HARDWARE MOD] [EXTERNAL SPEAKER] Increase your Xperia Z external speaker volume Mod*
Yesterday while playing with my phone and after becoming a victim of the low speaker volume post dipping in water, I just found out that the external speaker's volume can be increased* on par with other competitor manufacturer phone by this method.
*Note: You WILL lose the waterproofness feature of the phone by doing this. Do this only if you're sure that you're not going to dunk your phone in the water the next time you want to show off. You have been warned.
So for this mod, all you need is a tiny sharp pin, gentle hands and patience.
I do not have any pictures to post at the moment but I guess this is a fairly simple task and anyone can perform it.
Using the sharp pin, pry out the shiny plastic frame just at the end of the external speaker. Only pry out the length of the speaker and not any longer because it's unnecessary. Then, you can find a tiny strip of micro porous membrane. This is what protects the phone from water ingress at the speaker output. Carefully peel out the membrane ensuring that it's not being damaged while you do this.
Just to confirm that this mod actually does help, you can perform your own test. Play your favourite song in Walkman, and peel and unpeel the membrane and notice the difference in sound output.
This mod will also help people who have very low volume after dipping the phone in water. Just peel the membrane a bit and then reattach it properly ensuring its properly sealed. This should solve your low volume problem. Press the frame material by applying force at the speaker area to seal the frame properly.
There you have it, it's not that the speaker is crap or the volume is too low in this phone. Things have been kept to a maintain a balance between durability and function.
Please do let me know if you like this mod and if it has helped you, hit the thanks button.
