Arguably, it does make sense.
The Xperia Z4, announced not too long ago for Japan as an exclusive (and as the company’s new flagship smartphone), will be renamed for an international launch in June, dubbed the “Z3+”.
But, why not? The only real differences are Android 5.0 Lollipop, a new processor, a 5 megapixel front-facing, and a smaller battery 2,900 mAh (from 3,100 mAh). Other things have been fiddled with, like the new exposed micro USB port, which reportedly does not affect the waterproofing, or the overall design of the phone, which has been cleaned up and refined for slight imperfections.
Still, with Samsung dominating the Android space with not one but two flagships — S6 and S6 Edge — along with Apple’s own iPhone 6 and 6 Plus, the only reasonable strategy for Soyn at this point is to deliver another well-received smartphone, and hold its ground; profit dents aren’t in the cards here.
