U.S.-based Internet search giant Google Inc. seems to be on a roll. A day after it released an update, 4.0.2, for the LTE version of the Galaxy Nexus, the company formally announced an advanced version, 4.0.3, for mobile users and developers, within the next few weeks. The announcement comes after Samsung Nexus S users (on GSM networks) have also been told to expect an update to Ice Cream Sandwich.

Going forward, we'll be focusing our partners on Android 4.0.3 as the base version of Ice Cream Sandwich, Xavier Ducrohet, the Android SDK Tech Lead, wrote in a blog on Google's Web site on Friday, adding, The new platform will be rolling out to production phones and tablets in the weeks ahead, so we strongly encourage you to test your applications on Android 4.0.3 as soon as possible.

The forthcoming upgrade includes bug fixes and performance improvements for smartphones and tablets. Some of the new upgrades are improved calendar optimizations and video stabilization for camera applications. The key improvement features an upgrade from the current API 15 to a new social stream API, allowing users to view streaming data of connections in real time by linking social media sites to contacts.

Google also promises enhanced content accessibility and status/error reports for text-to-speech systems. It also sports upgrades in graphics, database, spell-check and Bluetooth.

Finally, developers can get a taste of freshly released versions of the DK bugging tools, along with the r7 NDK tool and the Eclipse plug-in for developing Android applications.
