Do I need to change the Loudspeaker?
I used my phone (sony xperia z) under the water for about 15-20min for taking some photos, after that as usuasl water got in the loudspeaker hole.
Left the phone for about 1-2h to dry and after that sound coming from louspeaker was the same (low, vaguely...) so i tried to take the water from loudspeaker by myself by shaking the phone and hitting it to make the water get out. Water got out but after 2-3 hours i noticed that loudspeaker isn't working at all and when i shake or push the phone on the place where is the loudspeaker (on the sides and back) it sounds again, then it stops and with a little shake start to work and again stops... it's like i disrupted some connection. The loudspeaker by it self it's working it not damaged but some connection or something inside is disrupted (i think).
So is there any way to fix this thing by NOT opening the back cover? or any other suggestion ? Thanks !
