Siri mic don’t hear me-front camera static noise/no voice to text

My iPhone 7 Plus mic for Siri doesn’t work -she doesn’t hear me and on the selfie(front) camerA makes a static noise. No audio.

I can’t voice to text .

I also notice on the back camera- if it’s silent, that same noise will be there but if I speak it lowers down almost not there.

My phone calls and voice memo DO work.

I suspect droplets of water may have Caused this issue, I was washing out tie dyes and my phone was right there next to the sink collecting water on the screen.. :-(

Help please!
