Design and Build :

Asus Zenfone Zoom is definitely Asus’ most premium smartphone with machined aluminum sides and the leather rear cover. The back of the phone is dominated by the camera along with dual tone LED flash, laser autofocus.

The device is pretty heavy at 185 gms and considerably thick at 12 mm. All in all, this is the best premium looking phone so far from Asus.

Display :

The Asus Zenfone Zoom sports a 5.5inch full HD display with a Corning Gorilla Glass 4 protection. The Display is not as great when compared to other phones in the same price segment. The Brightness appears to be low at times which I think can be corrected with the software tweaks (updates). The viewing angles are pretty decent and touch response is also pretty good. Below the Display are the three touch capacitive buttons which are not backlit.

Software :

The Zenfone Zoom is packed with the custom Zen UI over the Android 5.0 . Zen UI is not much changed compared to its previous version and it opens a whole lot place to play with. There is an app drawer unlike other Chinese ROMs and you can organize your apps in lot of ways.

You can automatically group / sort apps based on their category. The Notification bar and the quick toggles can help you operate your phone easily.

You can also use gestures like double tap to wake, double tap to sleep, as well as motion gestures. Multitasking is easy and you can pin your apps. You can also download icon packs along with themes from Play store and install them. The UI is smooth to work with and there were no lags experienced.

Hardware :

The Zenphone Zoom is powered by a 2.5GHz quad-core Intel Atom Z3590 processor coupled with PowerVR G6430 GPU and 4GB of RAM. Even though Zen UI is a heavily skinned UI with a lot of bloatware, it still gives you great performance.

During the usage of phone, switching from one app to other went smooth and most of the time, there was around 2GB of RAM available for use. There was no lag experienced and performance of this device seemed to be good enough.

Apart from the above specs, the phone sports 128 GB  of ROM which can help you store your movies, install lot of apps and games. And if you feel that the storage amount is less at your disposal, then you can even expand the memory with the help of micro sd card till 64GB. The phone comes with single SIM card and has support for 4G LTE in India.

Camera :

Now comes the part which the Zoom boasts the most. It has the 13 MP rear camera with the 3x Optical Zoom, OIS and has an innovative 10-element HOYA lens arrangement while at the front, it has 5 MP camera. Its quite interesting to see how Asus managed to pack 3x optical zoom in such form factor. Apart from the Camera, it has laser auto focus as well as the dual LED flash for the natural photos.

There are dedicated keys for the camera as discussed which works in 2 steps. Slightly pressed, the camera key helps you lock the focus and other elements and then pressing the key further gets your photo clicked. After the 3X optical zoom, one can digitally zoom via it upto 12X. The volume rockers can be used for zoom in and zoom out if one does not want to pinch in and out on the screen.

The Camera app is the usual Pixelmaster app which zenfone features usually with tons of options. While the auto focus works pretty fast but clicking the photo and getting it saved takes some time.


The Camera samples we got were good enough in the day light conditions. The colors appeared good and the optical zoom worked as expected without the loss of clarity.

The phone is although not capable of recording at 4K but FHD recording works well enough. The front facing camera is decent enough for the selfies with variety of features.

Battery :
