Comment iPhone 4S speakerphone quality... (Score 2) 239
The fact that the A5 processor incorporates some fancy noise cancellation technology goes beyond enhancing Siri voice recognition, and explains the startling difference in speakerphone and handset call quality I have noticed after upgrading from the iPhone 4. The 4S is easily one of the best sounding smartphones I have used in recent memory.
Not that iPhone 4 call quality is terrible, it's just that the 4S is that much better.
