Problem uploading files with the Android browser

When I upload files from a phone with Android though the default web browser, the process of uploading is satisfactory, but the file is not accesible. If I use for example Chrome, all ok. I´ve Elgg 1.8.10 and tested in two smartphones.

Thanks in advance.
