How you change the speaker? Anyway clean the hole from where the ringer sound came from or post more details on what you try & not.

Sorry

Changing the speaker is just to take it out and put the new one , I don't see anything to clean here . I though the vibration was from the fromt board but was not the case, I tried to isolate the speaker to the front board but atill the same .

Cheers

check the uem and upp, possible that its faulty or there's dry joint
try to maybe give light rework if its not glued!

Good luck

try also changing the AF AMP, think circuit ref, N150 (not too sure thou), but yes AF AMP, if still no, then UPP

i had one with same problem, i replaced the buzzer by cutting the frame open inside, and put back a other one and glue it back again ;-) takes some time, but is ok if you don't find the frame ;-)
if you cut in the inside side of the frame , nobody will see this from outside the phone...
