One day y wake up like normally and make a phone call but y couldn't hear that person then y turn on speaker and then y was able to hear that person. So y went and got my friend phone and call my self from that phone pretty much every thing works fine except the ear speaker the mic work the speaker mode work but when y put it on ear speaker mode no sound come from there. Y went and downloaded and app to test the speaker, and both the normal speaker and the ear speaker work completely fine which means that the ear speaker is working. But it does not work while in phone call, also try on whatsapp and is the same problem.
