Connect JUST as charging With ICS my phone now ALWAYS mounts my SD card as an external drive when I plug it into a computer. Sometimes I just want power, especially if I am trying to play a game that's on my SD card.
Under the previous version I had the option to connect JUST for charging, without talking to the computer at all. Is there a way to get this functionality back w/ an ICS device?
Answer

With Android 4.0 ICS, charge only mode is no longer available.

Unfortunately there's no app to deal with this issue AFAIK.

You can try, but I believe that this isn't possible with your phone, but for future readers, placing the phone in "media transfer mode", allows access to SD cards on both phone and computer.



Further into this matter

One can always disable the "automount" feature from the host OS:

Windows 7


Click "start";
At the search box type "autoplay";
Select "AutoPlay" from the search results list, should be under "Control Panel";
Find the "Mixed content" option and select "take no action" from the selectbox.

This will effectively disable Automount for devices like mobile phones. By my tests, the phone doesn't ask to "turn on USB storage" either.


Ubuntu


Using GUI:


Access the "Software Center";
Search for "dconf editor";
Install and after, open it;
Navigate to "org" -> "gnome" -> "desktop" -> "media-handling";
Un-tick "automount" and "automount-open".

Using Command Line:


Open the terminal;
Type gsettings set org.gnome.desktop.media-handling automount false.

Use true to enable it again.
