I have a Samsung phone and a hp pavilion laptop. I am trying to import photos I have taken on my phone to picasa 3 on my laptop. Perversely, the laptop will import photos copied from facebook but not those I have taken myself on my phone. The laptop recognises that my phone is plugged into a usb socket. Is there some phone unlocking process I must go through or is there a problem with my security software on my laptop (Kaspersky)?
