Galaxy S3 Cannot Use SD card

For a week or so my Galaxy S3 use, see or format the SD-card. Tried restart, taking SD out etc. but nothing worked. Empty slots for notworking programs are all over the phone. Could not remove the non-existing apps - which is messy and weird.

Log ...
  • Software update - did not help.
  • Reset to factory settings - 
One week later

So far no progress. By now I just use the phone for talk and sms. So not-smartphone. Trying another update.

Found this - it seems that the SanDisk app is the cause of the problem.

Comtrol DSLR camera via USB from commandline in Linux

My first gphoto2 image


Install gphoto2

# sudo apt-get install gphoto2
Run gphoto2 from the commandline. Here are some options:

# gphoto2 --capture-image-and-download

The camera will take a picture, and save it to the active folder.

# gphoto2 --list-device

Will tell the name of your camera.

On my SONY A58 the USB-setting in the menu must be "remote PC".

For samples see the man file, or "Using gphoto2".



After installing gphoto2 you can write a bashscript and call it automaticly via anacron or crontab.

In order to see whether your PC is able to connect to the cam, try this:

# gphoto2 --auto-detect
