Some days ago my Note begin to have some strange comportament.
Only when I make a traditional telephone call I can't hear and other person can't hear me, all mute. But whit speaker I hear other person, but he doesn't hear me.
The microphone works well (registration works perfectly), and also the speaker, so we can exclude an Hardware issue.
With other programs like Skype all work great.
The telephone was whit stock firmware (2.3 updated), so I decided to upgrade with Kies to 4.1. The problem remain!
I try with a factory reset, but nothing change.
So I decided to flash another rom, like CM11 and MIUI, but the problem also remain quite the same!! Now I can hear the other people, but he doesn't hear me.
It's so curious.
I can't realize if is a Hardware or Software problem.
Thanks in advance,
