Design and Display

Question: How is the Asus Zenfone 3 Ultra design?

Answer: It does turn heads, not for the right reasons, though. Most people were convinced that this is a tablet when they first saw it, and I am not sure if the two form factors any different anymore.

With the Zenfone 3 Ultra, Asus isn’t going that extra mile to fit in a 6.8-inch display in, say, a 6.44-inch phone body. It’s unabashedly a big phone, but at the same time, measures have been taken to make this as user-friendly a Big phone as possible.

If it were any slimmer, you wouldn’t get that optimum grip and if it were any broader, handling it would have been a bigger pain. Also, the volume rocker on the rear is relatively easier to maneuver when you are making calls or holding the phone in portrait mode.

The fingerprint sensor is on the front and works reasonably well. This is perhaps as comfortable as it gets with a 6.8-inch display phone.

Asus is also using flat metal rear and rounded metal side frame (with chamfered edges). In a way, the choice of materials used further ascertain its position as a smartphone.

Question: How is the build quality of the Zenfone 3 Ultra?

Answer: as mentioned, the full metal build makes it a solid 233grams mass, but there is some gap between the touch glass and display resulting in some flexes. This, however, shouldn’t be a problem and will also help protect the touch glass from shattering in case you drop your phone (which is quite likely here). Also, the home button juts out a bit which makes it prone to scratches.

The display is bright, has wide viewing angles, a blue light filter for extended reading, high contrast, wide dynamic range, and is well suited for consuming multimedia content. It isn’t a QHD display, but full HD works fine since it’s an IPS LCD panel.

Question: How is the outdoor visibility? Does the Asus Zenfone 3 Ultra has the option for automatic brightness?

Answer: Yes, auto brightness option is present and works well. The display is legible under direct sunlight.

Question: How is the day-to-day or general performance? How is gaming performance of Asus Zenfone 3 Ultra?

Answer: The Zenfone 3 Ultra is powered by Snapdragon 652 octa-core processor which is a capable performer, yet is a decidedly mid-range SoC.

The performance is great outdoors under direct sunlight, but in artificial indoor light, there is a lot of noise in images. The camera software is feature rich but slows the camera app a bit.

While the camera performance is certainly decent, it can’t match the likes of OnePlus 3, and other tier one branded competition.

The interface is loaded with customization options and that’s a good thing because since this is a unique device, you will need to program it according to you individual needs. The one option we used most frequently was the one-handed mode that can be triggered with the double pressing of the home button. Considering the sheer size of the handset, this works very well.
