AT&T, Sprint, Verizon Nix Download Booster from GS5
Samsung's Download Booster, a feature of the Galaxy S5 meant to improve file download speeds, has been removed from the device by AT&T, Sprint, and Verizon Wireless. The companies did not provide a reason for cutting the app. T-Mobile will be the only major U.S. carrier to support the feature. Download Booster splits file downloads between Wi-Fi and LTE in order to create faster speeds. AnandTech reports that Download Booster only works with files from apps such as the Google Play Store, YouTube, Facebook, and the browser that are larger than 30MB. Download Booster's usefulness will vary depending on local network connections.
what a narrow view...
With all three providers having moved toward, or moving toward data limits and caps on their network, none of these carriers are going to support anything that has the potential to put data on their network in that fashion, but more so, why would they wanna get customers complaining that they downloaded over "WiFi" and found that they went over their data cap - there by forcing the carrier to raise their unrealistic low data allotments?
I mean, think about it.
Would have turned off anyway
