All in all, The Zenfone 4 and Zenfone 4 Pro are both improvements over previous Zenfones. The ZenFone 4, in particular, is a solid option in its price point, so we’re pretty confident in saying that there’s never been a better time to try out a Zenfone – especially if it’s the Zenfone 4.

We like the design and the feel of the Zenfone 4 Pro and the hardware certainly paints in impressive picture. There's some side-stepping you might have to do to tame Zen UI, although Asus has also reduced the bloat in its Android skin - while also promising that there will be an Oreo update coming down the line too.

That pretty much wraps up this quick review for the Asus Zenfone 4 Pro. We’re really eager to be able to test out this bad boy to see what it can really do. The global price for the Zenfone 4 Pro has been set at $599 or Php 30,773; expect it to come up a bit more when it hits our shores. Local pricing and availability should be announced on Saturday, so stay tuned.

Qualcomm Adreno 540: Integrated graphics card in the Qualcomm Snapdragon 835 SoC. Slighly optimized architecture compared to the Adreno 530 but with higher clock speed due to the new 10 nm process. In the beginning of 2017 one of the fastest graphics cards for Android based smartphones.
Non demanding games should be playable with these graphics cards.

This display is quite big for a smartphone but frequently used for smartphones.
Large display-sizes allow higher resolutions. So, details like letters are bigger. On the other hand, the power consumption is lower with small screen diagonals and the devices are smaller, more lightweight and cheaper.

Only few smartphones are more lightweight than this.

The company's 2007 revenues reached US$6.9 billion. ASUS also produces components for other manufacturers. The Eee PC initiated the netbook boom in 2008.
In the notebook sector, Asus had a global market share of about 11% from 2014-2016, making it the fourth largest laptop manufacturer. In the smartphone sector, Asus is not among the Top 5 and has only a small market share (as of 2016).
77.25%: This rating is not convincing. The laptop is evaluated below average, this is not really a recommendation for purchase.
