Loudspeaker not working after drop
Today I dropped my LG G2 VS980 while it was in its case. Immediately afterward, the main loudspeaker (near the microUSB port) stopped working. I later discovered, quite by accident, that I could get some sound by holding it vertically and holding the volume up button. From my searches, it seems most likely that the speaker came unseated, however I want to make sure I have been through all of my options before I attempt to disassemble the phone. I have rebooted with no success, and when combined with the fact that audio stopped working the second I dropped the phone (I had audio playing at the time), I doubt that it is a software problem. That said, I can provide software specifications as needed.
Thank you in advance.
