hello this is my first post so sorry if its not very detailed but yesterday when in a phone call with my dad i put my phone on speaker phone so i could look at something on the mobile browser while talking to him...halfway through the conversation the speaker stopped working and i cant hear anything in call or oout through the speaker.... i had the same issue the day before but i just restarted it and it worked but this time it didnt any help please? ive just noticed that if i put my ear directly over the speaker i cant faintly hear it
