Asus Zenfone 3 (ZE552KL) Review – The third Generation of a legacy

Asus first came up with the Asus Zenfone in 2014. Mainly targetted at mid-range segment of smartphone buyers, the device was a great success. The second generation could not repeat the success story of the Zenfone though. Maybe it had something to do with the stronger competition.

For 2016, however, Asus seems to have a different strategy ahead. The focus now has shifted towards the premium segment. Asus Zenfone 3 looks forward to competing with the giants like Apple and Samsung and other such bigwigs.

Design and build

The Zenfone 3 is a completely different model from the predecessors. It comes with an all new design parameters. The reasoning is quite obvious. Asus wants to shed its tag of being a budget brand and move towards being a premium device maker.

In a stronger departure from what has been the current trend of using an all-metal unibody design, Asus has introduced something entirely different. The Asus Zenfone 3 has curved glass both on front and rear. The glass on the either side is secured by a metal frame.

The space below the screen houses the capacitive buttons for Home, Back and Recent Apps buttons. The tactile feedback of the buttons is quite easy. There is no backlight, though. It could be a reason for some worry.

The physical dimensions read 56.4 x 77.4 x 7.5mm and it weighs at 155 grams. That would make it neither lighter or slimmer, but the importance being paid to the comfortable handling makes it a good choice. The glass on either side may make it a little slippery, but not to the extent of making it uncomfortable.

The images shot in low light like the indoor shots have a great detail. That could be because of the high-end focus technology. The flash works great in lighting up the dark shots. Zenfone 3 can record videos at HD and full HD resolutions. You also have 4K video recording functionality.

The UI is quite cleaner and comes with some new features not available in the previous versions of Zenfone models. ZenMotion is a neat and great addition that supports some nice gestures. There is also an app named Mobile Manager which lets you control different settings including managing your app permissions and RAM usage.

There is also a Theme Store to find your favourite content.However, one of the points that we did not like is the plethora of preinstalled apps. We wish Asus had lowered the number of them.

There are apps like PhotoCollage, Do It Later, Share Link, ZenFone Care, ZenTalk, Laser Ruler, Quick Memo, Splendid, Puffin, ZenCircle, ZenFlash camera, and MyAsus Service Centre. Many of them are probably never used by most of the users.

Concluding thoughts

Well, at Rs. 27999 it would definitely be a good choice. There are many positive points in favour of it. Faster and smoother performance and UI are one of them.
