Sony's portfolio of non-Ericsson branded phones has just received two more additions, though they aren't much more than variations than the already-announced Xperia S.

The Xperia P features: a 4-inch "WhiteMagic" display, optimized for viewability in direct sunlight (for comparison, the Xperia S has a 4.3" display). It also features a 1 GHz dual core processor, 8 megapixel camera, NFC, and HDMI connectivity. The Xperia P will also launch alongside the SmartDock, which allows content on the phone's screen to be streamed to a TV.

The Xperia U is similar, but offers a nice alternative for those who aren't interested in the recent slew of giant phones. It features a 3.5" Reality Display, 1 GHz dual core processor, and a 5 megapixel camera.

Both devices are running Android 2.3 with a custom skin by Sony, but should both receive an upgrade to Ice Cream Sandwich sometime after launch. Read the full press release below.

Xperia P and Xperia U join Xperia S in the Xperia NXT series - next generation smartphones from Sony

Xperia P delivers outstanding screen brightness using Sony "WhiteMagic" display technology

Xperia U packs powerful Sony entertainment in a stylish and compact design

Sony Mobile Communications today unveiled the latest additions to its Xperia™ NXT series - next generation smartphones from Sony, the new Xperia P and Xperia U. In addition, Xperia S, the ultimate HD smartphone, is now shipping to markets across the globe, with first sales in the Sony Style store in Barcelona during Mobile World Congress. Xperia P and Xperia U will be available to consumers globally in the second quarter of this year.

Xperia NXT series - a connected entertainment experience

Incorporating the best of Sony technology and premium entertainment, the Xperia NXT series is a cornerstone of Sony's connected experience. With easy connectivity, consumers can enjoy and share content on whichever screen best suits them, whether it's their smartphone, TV, laptop or tablet.

With the next generation of smartphone design from Sony, the Xperia NXT series has a look that is instantly recognisable. These smartphones have intriguing design features including the "transparent element", a band that encircles the base of the phone and also integrates invisible antenna components. The transparent element illuminates when receiving calls, texts and notifications.

The new User Interface (UI) follows the same design principles and enhances the Android™ experience - offering rich applications and content with a simple and clean look. A new album, video player and music player will deliver compelling entertainment experiences and the new UI design also allows consumers to access their favourite application direct from the lock-screen.

Xperia P and Xperia U boast Reality Display powered by Mobile BRAVIA® Engine for razor-sharp clarity, along with fast capture to take the camera from sleep to snap in a little over a second with a single key press. Both smartphones come with powerful 1 GHz dual-core processors for super fast performance.

As with Xperia S, Xperia P and Xperia U connect consumers to premium entertainment experiences with access to the Sony Entertainment Network*. Out of the box, consumers can watch the latest Hollywood blockbusters on Video Unlimited or listen to millions and millions of songs** through Music Unlimited.

Xperia P - ultra-bright viewing experience

With a full aluminium unibody design, Xperia P debuts WhiteMagic™ display technology from Sony for the first time on a smartphone. WhiteMagic technology delivers the brightest viewing experience; whether at the beach or on the ski slopes. Smart power efficiency automatically adjusts the brightness of the screen to the surroundings to conserve battery life.

The new SmartDock, exclusively for Xperia P, offers simple connectivity to multiple screens, turning the smartphone into an entertainment hub for the living room. Using a TV remote control consumers can easily navigate their smartphone's media content to watch their HD videos, the latest movies or favourite TV shows on the big screen. With USB support in the SmartDock, they can also use a wireless keyboard and mouse to write emails, browse and post on Facebook or watch videos from YouTube on their TV.
