speakerphone or that can arise if the sound from
the speakerphone or headphone leaks into the

processing power, which might slow down other
applications.
The recommended setting is On.
Automatically adjusts the microphone volume
level so that the other party does not hear the

microphone input or too low volume (due to too
low input level). The recommended setting is On.
