It seems like Google's Android 4.0 Ice Cream Sandwich was kicked into the pit of oblivion when Android 4.1 Jelly Bean landed on the circuits of Android smartphones. That's not really the case for Samsung Galaxy Tab 10.1 GT-P7500 users who have not yet received the official Android 4.0.4 Ice Cream Sandwich. It's never too late especially for an official Ice Cream Sandwich update.

Users were craving for Ice Cream Sandwich and now the official update is finally here for the Galaxy Tab 10.1 GT-P7500. It's just a bit late, but it still brings along some goodness that's worth tinkering with, such as improved performance, longer battery life, Face Unlock, and even more.

Want to give it a try?  You can manually flash the firmware update for Android 4.0.4 Ice Cream Sandwich build XWLP6.  This particular distribution is for the Poland region (which includes Austria, Belgium, France, Germany, Hungary, Italy, Spain, and the United Kingdom) and reportedly works for tablets from other regions.
