samsung A127f sound problem solution,main microphone,top microphone and air phone not work solved.

This is a common Samsung problem that occurs after the phone is hit. The main microphone and the top microphone, as well as the conversation sound, are cut off. The reason for this is that the shield on the power chip, which is also the place where the I2C audio lines pass, is broken, which must be replaced after trimming the jumper. #irfix #mobilephone #phonerepair #repair #a127f_no_sound #a12 #sound_problem #jumper #trimming_board #no_mic #a12_mic_way
