The last Xperia C device was the Xperia C5 Ultra – a 6-inch phablet with extremely slim side bezels. It would make sense if the C6 actually tops that with a display that curves over its sides and creates the bezel-less appearance. That aside, the C series is where Sony's “selfie” phones reside. The company was among the first major manufacturers to produce a smartphone with more focus on its front camera performance, catering to the self-snapping youth of the 21st century — that was the Xperia C3, back in 2013. That aside, the handsets are usually equipped with midrange hardware and priced accordingly, so that the target audience of aspiring social media stars could see them as a viable purchase.
As far as hardware goes, here's what sources are saying – allegedly, Sony will limit the amount of Ultra models it produces this year, so the Xperia C6 may return to the 5.5-inch display diagonal that the C3 and C4 had, instead of inheriting the C5 Ultra's gargantuan 6-inch screen. The leaksters say that the display will have a 1080 x 1920 resolution, which will give it a pixel density of 424 PPI – more than enough for a perfectly crisp image. The processor humming underneath will reportedly be a MediaTek – the 64-bit, octa-core Helio P10 (a.k.a. MT 6755). No word on how much RAM would be on board, but if we had to guess, we'd say 3 GB, seeing as that's slowly becoming the norm even for midrange smartphones.
And that's all we can tell you about this semi-mysterious handset at this time. The Xperia C5 Ultra was announced in August, 2015, so we'd normally expect a refresh of the line to come after a few months. But who knows, seeing as Sony loves to play around with its smartphones' life cycles, we may just see this alleged Xperia C6 announced at this year's MWC, in February.
