ok, from the beginning, i got something on my phone yesterday (only on the screen) so i wiped it off with a damp paper towel and maybe i wiped past the speaker/microphone, im honestly not sure if i did. the phone was fine. well today when my phone rings or makes any kind of noise, it is super low and you can barely hear it! YES, the volume is all the way up. im just not sure what to do at this point. i've read up on all the moisture points and ive checked them out and nothing looks like its indicating water damage. my phone is out of warranty, i've had it about a year and a half. im not sure if it would be worth it to drive all the way up to the apple store just to have them tell me i need to buy a new phone. any suggestions?
