Sony had come into Mobile World Congress 2015 with high expectations. While their smartphones and tablets are never the first devices to be talked about in the Android community, they are always there – and have become one of the most reliable names in the personal and mobile computing industries. This time around, the company didn’t jump out and introduce a handful of devices that would be confused or misinterpreted by consumers. Instead, they delivered two devices that stood out from the crowd.

Sony announced the Xperia Z4 Tablet that would set out to be the lightest and slimmest tablet that measures at least 10-inches. Even more impressively, the 10.1-inch display measures in at 2K – that also makes it the brightest that has been seen to date. The Xperia Z4 is shipped with a 64-bit Qualcomm Snapdragon 810 processor. Combine that with a 6000mAh battery, as well as Sony’s Battery STAMINA Mode, and what you are left with is a device that can really deliver for entertainment. While this likely won’t be the first choice for anyone who is looking for work functionality, this will undoubtedly be the first choice for those who are looking purely for entertainment. That is not to say that the device wouldn’t function incredibly well as a work device; it just doesn’t lend itself to being that first, and foremost.

Then there is the Sony Xperia M4 Aqua, as its name suggests, it is waterproof. The screen quality isn’t over the top on this device, but again, it’s almost to a point now where screen resolutions are so good that the naked eye has a hard time distinguishing between different options. Combine that with the fact that it has got a 5-inch display, a 64-bit processor made by Qualcomm, which all leads to this device being incredibly responsive and fast. The biggest question for this device though isn’t whether the waterproofing will hold up, but rather how this device performs over the long haul. It is running a Snapdragon 615 processor that is fast – especially with the software that Sony has put inside, but it isn’t quite as responsive as the Snapdragon 810 processor.

However, with the challenges that Samsung had with the Snapdragon 810 processor in testing, this could end up being a significantly good move if the overheating issues that were present in some Snapdragon housed phones, end up having the experience and battery issues that were found in some manufacturer’s tests. In all, it would be hard to call this launch a failure, by any means.
