When I dial a number from an app like the stock Calendar that requires a conference code after connecting, it automatically dials that code, but very slowly. It's almost a continuous tone as it dials. Takes about 3 seconds for the code to be dialed. It doesn't matter where I dial it from. Stock calendar app, Plantronics App, etc. I swear my previous S4 dialed the conf. code extremely quickly. Is there a setting somewhere that can speed up this process?
