Seen the download booster in newer Samsung devices? Not only on newer devices, old devices, such as Galaxy S4, Note 2 that already got updated to lollipop, can use the download booster. Download booster is hidden in Settings, but it is available (haven't test it. Wifi at my house is broken). But you need to install Nova Launcher (or other apps that can add app shortcuts/activities.
Steps :
1. Install Nova Launcher
2. Tap and hold until Widgets button appears
3. Add Activities
4. While at Activities selection screen, scroll down until Settings
5. Expand it, and search for Download Booster
Done! Your phone will have download booster without having to buy S5, or newer devices. You can even use the hidden Private mode, and Greyscale Power Saving mode (not ultra power saving mode).
Hope this helps!
