Design & Feel

As usual let’s talk about the look, design and the feel of the Smartphone. The Asus Zenfone 2 has carried out the different design concept to deliver the best affordable Flagship Smartphone. On the front of 5.5 inches display, there is an Ear speaker on the top and carries an ASUS Logo just below it. To the right of the logo, there is a 5MP front facing camera with Wide angle lens. Down below the screen there are three touch capacitive navigations button but sadly they are not backlit enabled. So it takes a little time to get used to it to use the phone in dark conditions.

On the bottom side, there is a micro USB or charging port and it also acts as the data exchange port between the Smartphone and the computer. Next to the charger port, the Microphone is placed. Coming to the top you can find the power lock button, 3.5 mm headphone jack and the secondary noise cancelation Mic. Surprisingly there is nothing on the left and the right side of the ASUS Zenfone 2.

To the rear side there is a dual LED Flash, 13MP camera, and the volume rockers. Also, you can find the ASUS, Zenfone 2 and Intel inside branding. A big Speaker is placed at the bottom of the rear side. Now coming to the feel of the Smartphone, the ASUS Zenfone 2 ZE551ML feels premium in the hands. Though the rear panel is plastic, it has some metallic finish which makes the phone very comfortable to hold. You don’t feel the phone is too big as it has good design and form factor. But we advise you to install some back covers as the back panel gets the scratches easily.

One Hand Mode

Asus Zenfone 2 ZE551ML has 5.5 inches HD display with the resolution of 1080×1920 pixels and 403ppi pixel density. On the protection side, the phone is covered by the Corning Gorillas Glass 3 on the top. The display is so crisp and the viewing angles are extremely good. Also, the device does the excellent job in the sunlight as we could see the display without any trouble.Though the phone is protected by the Corning Gorilla Glass 3 it’s highly recommended to install tempered Glass or any kind of Scratch card as it takes little scratches easily. You can even choose the Screen Color mode according to your usability and some of the modes available are “Balanced Mode, Reading Mode, Vivid Mode and Customized Mode” . I personally use customized mode to lower the Hue and Saturation and use black and white display when I use my phone under the bed sheet 😛

Also, there is an option for “One Hand Mode” so that you can use your phone in a single hand while traveling or when your are busy with other works. You can enable the “One Hand Mode” from the quick setting or double tap the Home button to get it. To enable this shortcut go to Settings>ASUS Customized Settings> One Hand Mode and enable the Quick trigger. If you can’t get your hands to the lock screen every time then there is an option to lock or unlock the screen by double tapping anywhere on the display.



Asus Zenfone 2 ZE551ML Performance

Asus Zenfone 2 is all about its performance. To the Specification part, the phone has 2.3 GHz Quad Core Intel Atom Z3580 processor aided by the 4GB of RAM and PowerVR G6430 GPU. This is the first Smartphone in the world to equip the 4 GIG RAM.I must say the performance is really smooth and lag less in the Asus Zenfone 2 ZE551ML.The phone gets the full use of 4GB RAM while multi tasking and heavy gaming. The gaming on this phone is a great experience, but the sad part is it gets heated up quickly while gaming.At some point, you might even stop the gaming and let the device to cool down. I have tested the device by running some high-end games like Asphalt 8, Hit man, Dead Trigger 2 at high graphics settings and it performed really well. Overall the Asus Zenfone 2 is excellent in terms of the performance except the heating Issue.


The Asus Zenfone 2 has 13MP rear camera with LED Flash and 5MP front facing Selfie Camera.The photos are processed by the Pixelmaster camera and the initial impression with the camera is pretty good.But after the full usage its not that great when compared to Xiaomi Mi4 or OnePlus One camera which are in the similar price ranges.The camera does the excellent job in the natural light and the output images looks good, but it does not provides much details.This is how the Camera UI of Asus Zenfone 2 looks like


The UI looks simple and you can simply click the capture button or the volume rockers to capture the photos.It has Zero shutter delay and you can click and hold to click continuous shots.Some of the modes available are Auto, Manual, HDR, Beautifications, Super Resolution, Low Light, Night, Depth or Field, Effect, Selfie, GIF Animation, Panorama,Miniature, Time Rewind, Smart Remove, All Smiles, and Time Lapse.The rear camera can record the Full HD video of 1920×1080 pixels resolution.Here are the few Camera Samples of Asus Zenfone 2 on various conditions.The image looks natural in the outdoor conditions and even the color reproduction is good.

The Low Light mode works great in the dark conditions.I am not impressed with the flash on the Zenfone 2 as the light is not spread evenly over the object.

UI and OS

Asus Zenfone 2 ZE551ML UI

The Asus Zenfone 2 runs on the latest version of Android Lollipop 5.0 with ZenUI on the top.The Phone comes with too many inbuilt bloatware Apps and the App tray looks so crowded.I always use search option to open the Apps as there are too many Apps installed.As the phone has the 16/32 and 64GB of internal Storage there is no problem of storage issue and it also has 64GB of Micro SD Card support.Apart from this the Zenfone 2 also has the OTG support for connecting Pen drives and Gaming controllers.The ZenUI has to be improved a lot but still it has some good features.You can locks and hide Apps without using any third party Applications.The Apps and the games can be moved to the Memory card and not the full data is moved.You can even customize the Quick Settings under the Asus Customized settings.The Android Lollipop allows you to add guest users and restrict others from accessing your settings and Apps.You can pin the Apps or games from the Recent windows and you can Unpin them by pressing and holding the back and the Recent Key.
