12/18/2009 Low Speaker Ringer Sound Volume Blackberry Bold 9000 compared to original settings fix
Not sure if my method was or was not mentioned. As I saw the tape/card methods being thrown around that keyed me to the problem area.
THE FIX: Without taking my phone apart (forgive ME I'm not technical with the phone parts) i found the problem with the low volume was in the light gray part with the flash and the black rivet looking things(the grey flash box is my name for it). at the top of the grey box theres a thin gap (as if u wanted to pull the grey part off from the top) and I simply took a thin object (razor, paper clip or something hard and slimmer than a butter knife) and just BARELY
started moving it around as a song played to see if it affected anything and it did. It needed to be pulled away just a bit so I took a post-it note and follded it til about 4 ply and wedged it.
My phone is back to its normal loud ring
Hope that helps and let me know if it works for you!
