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.

Asus Zenfone 4 Pro preview: The true flagship of the Zenfone family
Source: Pocket Lint English
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.

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. » Further information can be found in our Comparison of Mobile Graphics Cards and the corresponding Benchmark List.
835: High-End SoC for smartphones that was introduced in early 2017 and manufactured in 10 nm LPE FinFET at Samsung. Integrates 4x Kryo 280 at 2.45 GHz (max) for performance and 4x Kryo 280 at 1.9 GHz (max) for efficiency. Furthermore offers an X16 LTE modem, ac-WiFi and a dual-channel 32-Bit 1866 MHz LPDDR4x memory controller. » Further information can be found in our Comparison of Mobile Processsors.

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.


Asus: ASUSTeK Computer Incorporated, a Taiwanese multinational company, produces motherboards, graphics cards, optical drives, PDAs, computer monitors, notebook computers, servers, networking products, mobile phones, computer cases, computer components, and computer cooling systems. 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.
