Disclaimer: This
worked on my smartphone, and it should work on yours too. But do not
experimente because you could damage your speaker. If sound is too loud,
decrese it by Volume Down button while in middle of phone call.
Requirements: You will need a phone with MTK (Mediatek) chipset. If you are not
sure, google your smartphone and search for information under CPU or CHIPSET. I
do not know if it works with other chipsets.
