Sony has announced today that it’s Tablet P and Tablet S are scheduled to get the Android 4.0 (Ice Crem Sandwich) update at the end of April, just like a host of other tablets. They have also announced that they will be adding certain photo functionalities like the ability to activate the tablets’ cameras directly from their lock screens, edit photos in the gallery application, and take panoramic photos. These camera features were previously found on Sony’s NEX and Alpha series digital cameras. The update also allows Sony Tablet users to watch programs they’ve recorded on their compatible Sony Blu-Ray recorders with a downloadable app. Some of the features are for Japan only right now, but keep checking back for updates.

Also announced is the introduction of “Small Apps.” With these small apps people will be able to open up a small calculator, remote control, or browser window on top of the currently running app. This new feature will probably only be available to apps that the developers have added the support to, but Sony shows this being used with big apps like Youtube and google maps.

Sony has also announced a Wi-Fi-only version of its dual-screened Tablet P, going on sale on April 21st for about $600. Aside from being cheaper and lacking a 3G radio, this is the same as the Tablet P. Also, for Tablet P users looking to add a splash of personalization to their devices, Sony will be offering colored interchangeable front and back covers in gold, pink, and blue for about $60 starting April 21st.
