    My loudspeaker doesn’t work and when I receive a call my mic doesn’t work, but as soon as the person hangs up and calls back the mic works . I bought a new loudspeaker assembly but have yet to install it.

  • Thanks when I cleared the mic hole it worked perfectly.

  • I have a Note 2 where the mic works during a call, but no one can hear me while on speakerphone. Any ideas??

    • Your Secondary MIC might be having problems, as when you switch to speaker phone your secondary mic becomes active. I also recommend that you should try your hands free first and check whether you are having similar issues or not.

  • Does the note 2 and note 3 use a different mic for speakerphone? Me and my friend are both having the same issue with our phones. He has the Verizon note 2, I have th T-Mobile note 3. Mic works in speakerphone mode, and in sound record. But in regular calls, nobody can hear a thing.

    • Yes the problem is your Mic rubber cap is displaced from its original location or it is damaged. Refix Mic rubber cap and check or if it is damaged then change it. This is surely going to solve your problem. This problems arises due to that.
