UPDATE 7 : MAGISK Module updated to match latest AQG5 Firmware and Camera Version. Fixed Camera Recording Issue

UPDATE 6 : MAGISK Module updated to Template v4 for Magisk 13.x

UPDATE 5 : v3 uploaded with better balance
between earpiece and main speaker. Gain adjusted to prevent crackle. This mod best combine with Dolby Atmos Module, use around 50-60% volume.

UPDATE 4 : Magisk Module for the Mod added - for you who are in stock and still wish for OTA, use it instead so that u can have the mod systemless way
UPDATE : New zip for dual speaker with increased gain added
UPDATE 2 : ORIGINAL file added, in case people forget to back up
UPDATE 3 : BOTTOM ONLY BOOST zip added

As all we know, our phone only has one speaker at the bottom,

So just like the rest of similar mod for other phone (ex : my Oneplus 3)

Here's the file mod you can use to make the earpiece (the one near your ear) of your phone to act as secondary speaker

Download attached file,

Place it in /system/etc and change permission to 644

Reboot

OR, download the ZIP file and flash via TWRP

For SYSTEMLESS METHOD, use Magisk version zip and install it through Magisk Manager

Try and report

If you need to adjust the gain yourself, find these lines in mixer_gains and adjust the 35 or 40 value to your liking :

<path name="gain-media-speaker">
<ctl name="HPOUT3L Input 1 Volume" value="35" />
<ctl name="HPOUT3R Input 1 Volume" value="35" />
</path>

<path name="gain-media-headset">
<ctl name="HPOUT2L Impedance Volume" value="107" />
<ctl name="HPOUT2R Impedance Volume" value="107" />
<ctl name="HPOUT2L Input 1 Volume" value="40" />
<ctl name="HPOUT2R Input 1 Volume" value="40" />
</path>
ORIGINAL MOD CREDIT goes to @MichaelGroth

Flashable TWRP & Magisk ZIP by me.

Thank you @silvercat who brought this info on another device thread, and to @topjohnwu who made the systemless method for this mod possible through his Magisk creation.

Too bad the phone has to be rooted. Used this on my s7 edge and it was an excellent mod :) Happy to see this brought to the s8, too bad I cannot use this :)

Any chance of a volume mod for only the bottom speaker? Dual is nice but don't wanna risk a blow out.
There is no risk of a "blowout". The earpiece speaker is a sort of tweeter so not that loud, and the bottom speaker is the loud woofer. I have used this mod for the s7 for a year and now using it for the s8 , no blowouts here! go for it mate its all good.

i had it also on my s7 edge and loved it! i would much like additional confirmations from others. would ultimately like a bottom speaker only mod with lvl 3 as zubis or dual with lvl2. prefer lvl3 with bottom only if anyone can help me out plz
