I recently received a Samsung Galaxy Tab 2 7.0 with Android 4.1.1 on it. This is the 8GB model. I am curious to know, how much disk space does the Android OS take up? I did not think about 3.5GB was needed for the OS. Is this true? I ask only because my disk space available says I have 4.49GB left.

There's a difference between "how much the Android OS requires" and "how much the manufacturer reserved". Remember, the OS has its own partition (/system), which is mounted read-only during normal operation (just made writable for OS updates), while the user's data goes to /data. Moreover, most manufacturers add their own "presents" (also known as ) to the /system partition.

So while the actual Android system usually fits into less than 1 GB (considered there are devices shipping with less internal storage), your device's manufacturer might have decided to reserve more space for future updates and his own add-ons.

    Just to clarify, examples of these add-ons are bundled software (facebook, customized calendar app etc.), customized user interface/launcher (TouchWiz) and the whole S Pen software. – onik May 8 '13 at 6:34
  • how would I check how much the manufacturer reserved. I'm just trying to figure out why I only have 4.49GB of space left – bob Glenn May 8 '13 at 20:26
  • Either use adb shell or a Terminal app (e.g. Android Terminal Emulator, and run df. The "reserved area" is mounted at /system. There are other partitions like e.g. /cache which are not directly accessible to you; "userland" is /data, where you should find your 4.49 GB. – Izzy May 8 '13 at 22:41
