Chosen Solution
a few weeks ago i replaced my sisters screen that was bought from here(ifixit) and the ear piece isnt working the way it should be the volume is all the way up but sounds like its whispering ever since i replaced it
If your system volume is down, then obvious answer is you need to turn the system volume up, but maybe your speaker got damaged t some point (water, etc.) and will need to be replaced, always a bummer, but what else can you do really?
