My mi5 basically shuts off all his microphones (there are two) and it seems like they arent connected (but they are detected like it) and i tested it with the troubleshoot app in the device info. Less often it broke the earpiece and the audio output by jack: after the audio goes away, the earbud remains as detected also if i remove them
I've not echo problems with earbuds. The problem is only when using the earpiece...I suspect that is something related with the proximity of the earpiece to the noisce cancelling mic. I've tried to disable (by software) the top mic with no luck....
