Looking for a way to lock files when connected to PC...

[RULINGCHAOS]

The gf has important files and folders on her phone that are sensitive to her job. (and some photos to be honest)

She tells me that even when locked, she plugs it into a pc and all the info pops up for anyone to see.
How can this be prevented?

As a side note: i plugged my locked S3 into my PC and it says "portable media player" under the system. But then i deleted all Samsung software from my PC because it was causing issues. When i plug it in now, it asks me if i wanna install the software.

Hmmm, why is she connecting it to a computer? Is it to transfer files, charge the phone......? Maybe someone can suggest an alternative to using the usb connection.

Both, I think. At work and at home. She is afraid that someone can just steal her phone, plug it into a pc and get access to all her data even if the phone is locked.

I see! Sounds like a pretty stupid design flaw. Maybe she should try to add a file locker app & store the sensitive data in there.
