iphone8 - extremely low earpiece volume
phone is about 4 months old, maybe more, not sure, but fairly new. Recently been having trouble with the earpiece volume being too low to hear the other party while in a call.
Searched around apple site, and saw many people apparently complaining of the same issue with iphone6/7, iphone8, 8plus, iphonex, along with nothing but useless 'fixes' or 'tricks'.
Finally I turned the phone off, took the old horse hair acid brush that I normally use to clean circuit boards, after soldering, etc. dipped in denatured alcohol as I would if cleaning a circuit board, and cleaned the earpiece speaker grill. dried it off, then fired up the air compressor and blew out the speaker grill for good measure.
All better now, just like it was when brand new... Issue must be dust buildup in the earpiece speaker grill.
Maybe save someone else the frustration by posting this here, along with another forum I frequent...
Drove me nuts for a couple weeks..., thought I was starting to go deaf!!!
