Just came back from local Verizon store. I ran multiple speed tests on both 928 and Icon which sit 5 inches from each other and both have 3 out of 5 LTE signal bars. The 928 (with black update) only has around 5mb/s download and 3mb/s upload while the Icon has 50mb/s and 10mb/s. I live in New York so the AWS network should be well deployed according to report. Then the only reason I can think of is the 928 is not AWS enabled.
