I am able to send files vie Bluetooth from my Ubuntu 12.04 laptop to an Android/Samsung phone. So I have set up that phone successfully as a device.
However, I am unable to receive files sent from my phone. For this, I select on my phone my Ubuntu laptop which is listed as present and send the file which results in failure after a few seconds.
Conversely I try to "Select device to browse" on my laptop, but my phone is not shown.
