Download booster is a built-in function, work great when we download file more than 30mb from play store but does not work when we download a file via UC browser, why ?
It does not work / has limited support with Third-Party applications.
Have a look at the following article by Samsung on their homepage:
What is the Download Booster and how do I enable it on my Samsung Galaxy Alpha?
It seems like that the download booster is only available when downloading via the integrated Browser / Samsung Apps / Google Apps. See this image for the download browser description: Thanks Samsung for providing this picture
The last sentence pretty much says that third-party applications might not work with the download booster.
I'm quoting the essential part:
- This feature supports Hypertext Transmission Protocol (HTTP) 1.1 only.
So, It can be activated in Play Store, Samsung Apps, Samsung Video , YouTube, Play Movies, Play Games, Internet(S-Browser), Chrome (ChromeBrowser), Baidu, and not all applications.
The feature cannot be used with other protocols, such as HTTPS or FTP.
So, it’s not supported regarding to attached files of E-mail , Streaming service like Dropbox or Twitter
