Although many smartphones with a diagonal screen of 5.5 inches are habitually called phablets, they hardly deserve this name. The 5.5-inch display is gradually becoming the standard solution. Also, in the device with such a screen there is nothing that would have brought him to the tablet. However, Asus Zenfone 3 Ultra has every right to be called a phablet. Still, the device with a display, whose diagonal is 6.8 inches, can no longer be called an accessible smartphone.

Appearance and ergonomics

Appearance ASUS ZenFone 3 Ultra entirely corresponds to the sound design concept Zen. The device looks laconic, no frills and «decorations,» and at the same time elegant. He has a completely metal casing. When we say «completely,» we mean entirely. That is, engineers ASUS managed to do without plastic inserts, under which the antennas are hiding. The body is made of anodized aluminum alloy, durable and not afraid of corrosion.

The thickness of the shell is only 6.8 mm. The device can be gray, golden or pink.

Under the screen is a mechanical button. Pressing it allows you to return to the home screen. The button has a built-in fingerprint sensor. It can remember up to five different fingers, it works quickly and clearly, so there will be no problems with unlocking the smartphone. To the left and right of the mechanical key are the touch buttons «Back» and «Menu.»

The on/off button of the smartphone is located on the right side. It has a relief surface, so it is especially convenient and even pleasant to use. The knob of volume control was taken out by the developers on the back panel. Unusually, although this solution was found in other smartphones ASUS. Next to the power button are the SIM card slots. One of them is combined with a memory card slot.

At the bottom, there are stereo speakers, a microphone, and a suitable symmetrical USB Type-C connector. It is used to recharge the battery and connect the smartphone to other devices. At the top, you will find a 3.5mm headphone jack. Next, to it, you can see the auxiliary microphone.

The display is made using IPS technology without an air gap, and this provides a decent brightness and wide viewing angles. To the clarity and contrast of the picture, too, there are no complaints. The creators of the device used many solutions aimed at improving the image. It is important to note the technology Tru2Life +. It uses the same processing algorithms that are used in modern 4K-TVs. This allows you to improve color coverage, minimize blur and jitter when playing video. Also, this technology makes the image more clear, so small details become more legible. Due to this, the text on the screen becomes more readable.

Today it is fashionable to struggle with the blue glow emanating from the display, irritating the eyes and causing fatigue. ASUS did not forget about this, so the blue filtering function is also present here.

There is also an anti-reflective coating. Thanks to him, the device can be used comfortably in the street on a bright, sunny day.

All of the above means that the smartphone is great for watching videos. Such a little TV you have … I’d like to write «in my pocket,» but it’s unlikely to fit into his pocket. It’s better to say: «miniature TV, which is always with you.» By the way, USB Type-C connector supports DisplayPort capabilities. Thanks to this, you can output an image in high quality to a TV or compatible monitor.
