[Q] S4 dropped in pail of milk(!) - cleaned but mic works intermittently

[lchiu7]

There is more to this than I can fit in the subject line.

My wife dropped her S4 into a pail of milk (she works in a cafe), We were not able to clean it until the next day and we also stuck it in a bag of rice.

I took it it into a local repair place who removed the board, soaked it in cleaning fluid and the phone restarted okay. But apparently the milk had damaged the digitiser so that no touch was recognised on the lower part of the screen despite their cleaning the contacts etc. So bit the bullet and had a new screen/digitiser installed.

Now my wife tells me and I can confirm this, that when using two of her favourite apps for communication(Wechat and Viber) when she tries to record a voice message the mic stops working. In Wechat the level control doesn't show any bars. Or it will work briefly and then stop. But regular cellphone calls are fine and the called party can hear her. Out of interest I installed a recorder app and that works fine also. I can use the recorder app and then try to use Wechat and the recorder will work, Wechat (or Viber) won't.

It seems like this should be a software issue but everything was working before the milk incident and no software was updated when the digitiser was installed.

I guess we could remove both apps and reinstall them but my wife has long chat conversation threads on both apps which get lost if you re-install and she wants to keep them.

I plan to go back to the repair place to ask if they can see if there are any issues but this doesn't really make much sense.

Thanks

Get the mic module replaced.
@AntaresOne can you throw some light here

I will ask that but it's strange that regular calls are okay (must use the mic) and a digital recorder also works fine.

Erm..if you want to backup all the messages and stuff, try backing up.with helium/titanuim backup.

And reinstall the apps.

Well I backed up her messages (Wechat has a capability to do that), deleted the app, re-installed it and restored her messages. After being able to send about 4 or 5 messages with audio, the audio stopped working again.

It's hard to believe it's a hardware issue when the same mic works with regular calls and a digital recorder but next step is to factory reset the phone and see if the app behaves itself then.
