Recently, users discovered that with the new versions of Opera-mini and even the old versions, pictures, videos, apps and files that are below 15 MB could no longer be downloaded; not that the download feature doesn’t come up it does, but then, after the download feature is clicked, it only shows file downloading but never downloads the file.

After a deep research I got the solution to this problem and even on how to download files more that 15 MB with Airtel social bundle on opera-mini
