Hello everyone, i just bought an iPhone 4G to repair and this is the problem : The sound by headphone = ok/perfect The sound by loudspeaker = ok/good The sound by earspeaker = bad So the defaut piece the sound was bad quality and very very low i change the earspeaker (by an iPhone 4S one) and put a new one = no sound at all i change again the earspeaker by an other one (still iPhone 4S) = high volume sound but horrible quality = Sizzling/crackling I don’t get it, what can be ? Thank you very much for your help
Well i found it by myself… Methode = you inverse the normal sens (direction) of the ear speaker to make contact on a new “surface” of the pads and yeah it works perfectly; glad to help you bye.
