Buying a high-end smartphone isn’t easy, because there are so many to choose from, but that decision becomes even more difficult if you want a high-end smartphone in a small package; almost all of them now come with displays at least 5 inches big.

But not anymore, thanks to the Sony Xperia Z1f. It combines high-end specifications with a 4.3-inch display to provide a cutting-edge device that easy to operate with one hand and hardly noticeable in your pocket.

While the iPhone has been slowly making its way to carriers all over the world since its release in 2007, there are still a number of major operators that are yet to offer it. One of those is China Mobile, the world’s largest carrier with over 800 million subscribers; and another is DoCoMo, a Japanese carrier that serves almost half of the country’s mobile market.

But DoCoMo isn’t at all concerned, even though it’s losing customers to other carriers that do offer Apple’s device. A company executive has acknowledged that the iPhone is an “attractive” device, but points out that it also comes with some disadvantages, and insists that the latest Android-powered offerings are just as good.

The Sony Tablet S could soon have a successor.

Specifications for Sony’s upcoming Xperia Tablet Z were leaked on Wednesday, and we were looking forward to seeing the slate’s grand unveiling at Mobile World Congress in Barcelona next month. But according to one Japanese carrier, Sony’s new flagship tablet will be unveiled on the company’s home turf on January 22.
