As the title says,
I can't make any calls or record any audio because the ear piece speaker/microphone used for calls is no longer working - calls still go through, but I can only hear the call if it's on speaker, and the mic still won't work either way.
I've tried restarting the phone, removing/replacing the battery and a hard reset - still to no avail.
Should I go ahead and send for a replacement?
Nothing significant has happened to the phone to cause any of this - it's not been dropped, gotten wet or anything and the phone was working properly just earlier today.
