Lubuntu can't recieve files via bluetooth (from android phone)

view story

http://askubuntu.com – I'm using Lubuntu 13.04 on my laptop (Toshiba Satellite L310) and I'm trying to use bluetooth to connect it to my smartphone (Samsung Galaxy S4 mini) I've installed bluetooth manager and I paired my two devices successfully. I've send files from my laptop to my phone without any problems, however when I try to send files in my phone to the laptop, it doesn't work and I wonder why. What should I do? P.S. I've ticked my phone as 'trusted device' in Bluetooth Manager but it doesn't help Thank You (HowTos)
