Sony Mobile opened up its booth at Mobile World Congress in Barcelona, introducing the new Xperia Z4 Tablet and Xperia M4 Aqua. Sony Mobile Communications's new President & CEO, Hiroki Totoki, also took to the stage to share his vision for Sony Mobile’s future.

"We’re at a point where delivering a better user experience means going beyond what is currently available in the market," said Totoki. "We must redefine how products can enrich our lives with the communications possibilities that they create. And Sony Mobile has the innovators that will take these next steps."

"Our success will come not just from optimizing our core smartphone business – but from new ideas, new business opportunities and new ways of working. So that, no matter what challenges we encounter, we will deliver products and services that excite and entertain. We will minimize our business volatility, in this highly volatile industry."

"Mobile remains an important part of the Sony Group. And the reason for that is quite simple. Smartphones, tablets, SmartWear and mobile services are firmly rooted in our daily lives. They’re often the last thing we see before bed and the first when we see when we wake up," added Kazuo Hirai, President & CEO, Sony Corporation. "Sony has always been about doing what has never been done before. And the next phase of Sony Mobile is all about carrying that spirit forward, and making sure to entertain and ‘wow’ our customers around the world."

The new Xperia Z4 tablet features a bright 10.1 inch 2K display and long battery life (up to 17 hours of video playback). The Android tablet ’s IP68 waterproof and dust-tight rating makes it ideal for everyday use – now with a capless micro-USB charging for added convenience. For a laptop style experience, the BKB50 Bluetooth Keyboard features a dedicated slot for Xperia Z4 Tablet with 0-130 degree tilt for adjustable comfort.

The Xperia Z4 Tablet also includes powerful front stereo speakers along with Sony’s audio technologies. High-Res Audio reproduces high frequency sound in detail. DSEE HX processing upscales the audio fidelity of tracks to near High-Res Audio quality. Xperia Z4 Tablet supports digital noise cancelling for those times when you need to block out background noise. And for high quality wireless music listening, Sony’s new LDAC codec transmits data three times more efficiently than Bluetooth.

Xperia Z4 Tablet comes loaded with a 8MP main camera and a 5.1MP wide-angle front camera. It also comes packed with the Qualcomm Snapdragon 810 octa-core 64 bit processor, Wi-Fi and 4G LTE,connectivity and 32GB internal memory.

Its stamina is sure to impress with up to 17 hours of video playback, as a result of a 6,000mAH battery with Sony’s Battery STAMINA Mode, which turns off background functions when you’re not using them to help extend your battery life.

Xperia Z4 Tablet will launch globally, in 4G LTE and Wi-Fi variants, from June 2015.

The Xperia M4 Aqua is a mid-range smartphone, featuring a 13MP camera powered by Sony’s Exmor RS mobile sensor with a large F2.0 aperture, and ISO 3200 sensitivity. The Superior Auto Mode simplifies your interactions, automatically sensing up to 52 different scenarios. Just as with the rear, the 5MP selfie camera has a super wide-angle lens with an 88° field of view, and Portrait Retouch allows you to add fun finishing refinements.

Sony’s first octa-core 64-bit smartphone is featuring the Qualcomm Snapdragon 615 processor with integrated 4G LTE connectivity and up to two-day battery life.

The Android 5.0 Lollipop tablet has a tempered glass display, with a 136g waterproof (IP65/8 rated) body reengineered for cap-less microUSB charging.

Xperia M4 Aqua will be available in classic White and Black, but also fresh Coral and Silver. It will launch in 80 countries worldwide, across more than 100 carrier partners for around 299 EUR, from Spring 2015.

Sony also introduced the stylish Stereo Bluetooth Headset SBH70, a water resistant wireless headset with fine-tuned sound quality.
