Answer to: I can't hear my phone calls unless I put it on speaker.Just finished fishing mine out of a sink full of water while in a case.. phone was fully submerged for about five seconds but the case was full of water. Got the phone out of the case, dried it off and it still worked, but had the problem with the sound as above. Blew out the headphone jack, gently inserted some tissue to blot moisture, then blew on the earpiece and swabbed it out gently. I can hear calls now just fine, thank gawd. Also packed it into a bag of rice for tonite, just to make sure the water gets drawn out of wherever it may be hiding. But this trick works....used it a few times now. Cheers!
