2.Cleaning with double-sided tape
3.Cleaning with air sprayer
If the sound from your phone's speaker is too low, or if your voice is low while talking on the phone, this may be due to one of the following.
1.Clogging of the speaker grille or microphone hole by dust, dirt, cotton wool or the like
2.Oxidation of parts after contact with liquid, moisture
3.Breaking of the microphone or speaker socket due to the impacts
You can eliminate the first problem with the methods we explained in the video. However, for other problems, a technician must intervene and replace the damaged part.
