Hello,
Thank you for contacting us again.
This is a known issue that seems to come from the Android's browser itself. We found that problem logged in their tracking system - 1 and 2. In order to workaround that problem please add the following lines of code before the declaration of the RadAsyncUpload. Disabling - FileApi, Silverlight and Flash modules the control will upload the selected files at once (not on chunks).
Greetings,
Plamen
