Earlier last month, Samsung has unveiled 5.7-inch 1080p Galaxy Note 3 which became available on September 25th. However, it looks like Samsung should test the phone little more as the Sprint version of Galaxy Note 3 comes with some serious issues.
According to Sprint's own customer service forums, there are plenty of complaints about call quality issues. It looks like the problem is with poor audio quality while some users are experiencing dropped calls. The affected users have also run into the same problem with headsets, Bluetooth headsets and their speakerphone.
What is interesting is that VoIP calls sound fine and the problem is only limited to Note 3. Sprint has confirmed the issues and said that they are working on a fix.
