It wasn't all that long ago when China's Meizu unveiled its latest phone, the MX4, but the real flagship is actually what the company announced today. As you can tell from the name, the new MX4 Pro is a beefed-up version of the earlier model, yet it's still priced very competitively and is almost just as comfortable to hold. Most notably, it has a slightly larger 5.5-inch display with a stunning 2,560 x 1,536 resolution -- a tad more than the standard 2K resolution (hence the "2K+" label), thus making this the highest screen resolution for the current smartphone market. That said, this NEGA LCD panel is apparently very power efficient, sipping just 1.05 times the power consumed by the MX4's 1,920 x 1,152 screen. Underneath that lies a Samsung octa-core processor (2GHz A15 x 4 + 1.5GHz A7 x 4) which, according to Meizu, is 20 percent more efficient than the MX4's MediaTek offering.
