Have you ever experienced any issues with the top MIC after using v4a?

In my last 2 phones, Note 5 and S9+, when being on loudspeaker in a call, the other side would hear me poorly, it's almost as if once I install v4a, something happens to my top mics.

So although I want it now on the s21u, I am kinda scared. And I know it makes no sense as logically v4a is not supposed to touch the mic but.. :/
Hello. I've tested it using voice recorder, they seem to be working fine. I set the recorder to stereo mode, spoke to top and bottom mic. I played the recorded voice, I can hear my voice panning without distortion or voice getting weaker. So I assume they are fine.

Or your problem occurs only when on a loudspeaker in a call?

    Sadly my issue seems to be in the top MIC regardless of the situation. It's there even when performing the sound loop test. So I would assume either my mic is damaged or it got full of dust somehow. Probably it is just a coincidence that it happened and has nothing to do with v4a.

    Thanks though!

    Thats something i wanna know too,couldnt get it to work with the new patch😑
    @zidane02 posted these steps on the previous page, and it worked for me.. You will need a root file explorer.. the SH file you need is also on page 6, post #102, you will need to download that first, then follow the instructions below.

    Install in order

    Viper4androidFX via Magisk
    Reboot
    Audio Modification Library via magisk
    Reboot
    Push the file to data/adb/modules/ViPER4Android/ that i have uploaded and set permission 644
    (it should now be data/adb/modules/ViPER4Android/post-fs-data.sh)
    Reboot
    Open viper, set to legacy mode, then check if status is now normal

    Thats what i did when i can't make it work. the .sh file did the trick.

    Hello! Does this rom works with SM-G998N version?
    Thank you.
    N must be the Single Sim Korean version of the phone?

    In this case it will most likely work, but it would be best to get a confirmation from the Doc.

    A while ago I got a Korean Note 9, which I flashed with a standard B version ROM and it works flawlessly.

    The N and B are practically the same, other than maybe just the single sim..?

    I think so too. G998N is Korean Single-sim phone so i hoping it could work.
    I think i will wait till Doc confirms.

    I don't know if due to stock ROM or this ROM but... In landscape mode in camera app press "more" button in shoot modes will force close camera app...
    Only me or general bug?

    But that's very weird. You said you had that problem on your 2 previous phones. 3 phones in a row (including your S21U). Maybe some software conflicting the mic? I can't assume. The best way to test is perform a factory reset. Install v4a only and its related modules then test. If mics work, then some of your software probably is the culprit. I doubt that your mic is damaged or caught a lot of dust since it is new.

    I have tried, same problem....

    How was it? Did you manage to resolve your issue? Is it present when you were still on Stock ROM?

    No no the issue is only on my previous 2 phones. The s21u is fine but i have not yet installed v4a due to my fear haha :D

    The v4a being a culprit was just a theory. It seems more likely that the top MIC of the 2 previous phones got clogged with dust and maybe humidity reinforced the clogging. From steam in the shower to 60-70% humidity in the air where I live, could all be related. I would assume that the hole leading to the top mics is narrower than the hole on the bottom mic so that is why the bottom mics work fine overall :D Too many theories haha

    I see. Then you can try installing v4a now, you can just undo everything related to viper if things gone bad.
