Pro in a smartphone's name implies bigger and better - so much so that it's even been abused to fool the unsuspecting. Meizu did not resort to such trickery though and their MX4 Pro takes things up more than just a notch from the stock version.
An updated chipset and 3GB of RAM, a higher-res front cam, bigger screen and a fingerprint scanner are more than enough for the MX4 Pro to earn its stripes. But Meizu didn't stop there. They have the highest resolution screen on a mobile phone / phablet: 1536 x 2560px.
The Meizu MX4 Pro ditches the MediaTek chipset of its predecessor and has instead opted for the Samsung Exynos 5 Octa 5430, built around a 20nm processor and ARM's big.LITTLE architecture. It has four Cortex-A15 cores clocked at 2GHz and four Cortex-A7's at 1.5GHz each. Graphics are handled by the Mali T628 MP6/600MHz GPU and there's a stocky 3 gigs of RAM.
The CPU performance of the Exynos chip starts off impressively. GeekBench 3 ranks the MX4 Pro at second place among the many phones in the chart, interestingly just behind the Meizu MX4.
Compared to its predecessor, the Pro version of the Meizu MX4 didn't increase the screen size by much. The screen has grown 0.14" to a full 5.5" but the more important thing here is the higher resolution of 1536 x 2560px - up from the 1152 x 1920px screen on the MX4. The pixel density has increased significantly to 546ppi.
Meizu calls it a 2K+ display, but technically they are incorrect since 2K screen resolution means a horizontal line of around 2,000 pixels. A proper abbreviation would be QHD (Quad HD) or QHD+, if you will, in order to account for the extra pixels. QHD displays would normally have 1440px on the short side, while the MX4 Pro offers 1536px.
Like its smaller sibling, the Meizu MX4 Pro has a Sony 20.7MP sensor that's capable of capturing some huge 5248x3936px snaps in 4:3 aspect, matching the latest and greatest cameraphones from Sony themselves. Meizu offers what it calls Super high ISO that will allow the phone to shoot at up to 1600 ISO in low light conditions.
There's also a dual-tone LED flash that should allow for more pleasing colors in low light flash photos. Both LEDs fire simultaneously. Meizu claims that the MX4 Pro can acquire focus within 0.3s, which sounds like there are some phase detect pixels on the sensor, although we have no way to confirm that.
