If you're an ATT subscriber who pre-ordered a Galaxy S5, you may be met with some disappointment upon receiving your phone shipment through the mail if you were looking forward to the Download Booster feature. The feature, which Samsung openly praised and talked up during the MWC event in February is apparently completely absent on ATT models of the device. This was discovered by some customers who were already beginning to receive their phones and found the feature to be missing. While this may not be a problem for some, there will likely be some users who were actually excited to have this feature built into their device.
For those who are unaware, the Download Booster feature takes your LTE and WiFi connections and utilizes both of them to download files when you are downloading anything that amounts to over 30MB in size, provided you have the feature turned on of course. If you do, then essentially downloading an app that is a couple hundred megabytes in size would cause the Download Booster to kick in, and portions of the app files would be downloaded on each connection type, resulting in a largely faster download due to each connection picking up some of the slack. This takes all of the work off either connection. Customers would rightfully be more than a little upset about not having a certain feature that was advertised to them, but whether ATT had anything to do with their carrier model of the phone not having the feature or not, an update will probably come down the line that allows for it to be introduced.
It's worth noting that carrier models of the HTC One M8 were also missing one of their big features, which was the Ultra Power Saving mode, however the Sprint variant of the device had received it during an OTA update this week, so there's a really good chance that the ATT Galaxy S5 will end up with it's own update pretty soon that brings along Download Booster for the ride. If you were looking forward to picking this up on ATT's network specifically for this feature, it seems like you might have to be patient and wait for the update. If you really want the quicker download experience though you could resort to downloading an app like Super Download Fast, or Advanced Download Manager Pro, both which offer similar functions to Samsung's download booster feature.
