[Deprecated] The newest update to Android 4.1.1 (PadFone-10.2.4.1-0) lets user to easily remove SD card icon from status bar.

Android 4 stock ROM for Asus PadFone puts permanent SD card icon into status bar. You can't turn it off and if accidentally clicked Android unmounts the sd card...

I have found workaround for unrooted phones to disable sd card notification till next system reboot:

1. Expand status bar

Alter

2. Hold down your finger on SD Card notification until "App info" option appear. Click it.

3. You will see informations about "System UI" application. Tap "Force Stop" button to shutdown this app. Get back to home screen.

Alter

4. Here you are. Notification should disappear till next system restart.

If you have rooted your android you can try uninstalling "System UI" application but I don't know how this will impact on system stability.
