crackling loud speaker

[Feldort]

Hi
I bought my Xperia M4 Aqua 11 days ago. Altho I'm not from UK I got UK distribution. 
My problems is that the loud microphone is crackling, sometimes not working. I'm sure it's HW issue because when I tried S U C Kjust a bit speaker grill when speaker didn't work the speaker started work as intended. I grabbed it only twice with wet hands from hot bath. 
Now the phone is in a jar of rice. Should I get a warranty repair?
Thanks

just to clarify, did the phone came in contact with water>? if so the loudspeaker will be distorted for awhile until the water dries up.

are you playing hi res audio in max volume? then try to lower the volume and adjust your sound settings.

if you think there is hardware problem you have to send your device to your local service center Local support

That wasn't a direct contact with water. But it could evaporate some from my hands. But that's three days ago.

I'm not playing hi-res audio. Everything doesn't work. From Android sounds to my music. I have to press the screen in the corner where speaker is or S U C K speaker a bit. But it doesn't last for long. Half a minute maximally.
