Has the new update altered the sound quality of calls?
Since the new update yesterday when my wife phoned me we noticed a considerable update in quality of voice calls, we were calling it Call-HD at one then on other calls it would return to normal.
We also noticed a reduction in background noise, similar to when your on a VOIP call to a call centre and when the stop speaking the call goes almost dead as the noise is cut out behind them and then their voice shatters the silence again.
Has the update alter the voice calls on the S4 mini do we know?
Also I'm a Vodafone UK user if that helps.
