How is the speakerphone and call volume on the Note 4? My Note 2 was loud enough and clear, but my Note 3 was not as loud. I actually had to downloaded a volume app to make the phone louder. I read that the Note 3 speakerphone volume was lower because there was a channel the sound had to travel through to come out of the speaker at the bottom of the phone. Other people had complained about it on different forums. I use the speakerphone a lot and like it loud. Thanks.
