To all,
I am also having "echo" problems with all my calls on `the other` end with a brand new (~1 week old) Samsung Galaxy S5 w/Verizon. Even the rep at the Verizon store, with whom I upgraded from a Samsung Galaxy S3, acknowledged he had the echo "...a little bit...". I tried de-selecting Noise Reduction and Voice Privacy with no effect. Even a call from this phone to a land line, recipient had the echo on their land line phone. No known problem with the Samsung Galaxy S3. I liked it enough to want to upgrade. It seems that the problem is more pronounced on long distance calls. I plan on taking it back to the store for a "fix" to mine or a replacement. This problem is VERY real to the point that it's UNUSABLE for long distances. Date: 29-July-2014.
