unlike other download managers on my android that have high speed downloads on my 3G network,only opera mini has the slowest speed.it uses 2G speed(between 20KB/s and 50KB/s)for downloads even while am on 3G high speed network.i also cant download files above 15mb (download error).i just cant understand why this happens.
