In addition, the 4 machines have an in-screen fingerprint sensor, 2 Sim, 5G support, Red Magic 5S and Black Shark 3S still retain the 3.5mm port, and the other 2 are lost.

# 3. Design

Nubia Red Magic 5S design changes a lot compared to its predecessor: from a metal back to a glass back.

The machine has a radiator fan under the back, which makes its back still not flat. The bezel is made of metal, the heatsink for the fans on both sides, the trigger buttons L and R on the right side, the RGB lights in the middle and 2 sides.

Xiaomi Black Shark 3S still retains the X-shaped back layout, the camera cluster is quite unique, using a balance of both metal and glass materials, RGB LED in the Logo and 2 trigger keys on the right side.

ROG Phone 3 Still following the same design as the two previous models, that is: the diagonal radiator cluster on the right side of the back, smaller in size than the ROG Phone 2, with a USB Type C port on the side of the machine, the ultrasonic trigger key at right edge.

Legion Phone Duel has a Full glass back, with a rather odd design: the rear camera cluster is located near the center of the back with the recessed front camera module located on the right side with the trigger keys.

Legion logo integrates RGB LED in the middle of the back. It also has a type C port on the side just like the ROG Phone.

The basic colors of all 4 machines are Black and Silver Gray, giving a gaming look, along with some other quite flashy colors such as orange, blue, blue, red, …

# 6. Evaluate

Without too much discussion, it’s still the ASUS ROG Phone that wins. They are still really serious with the intention of dominating the Gaming Phone market.

ASUS ROG Phone features upgrades and technologies that other brands have neglected: sound, display quality, operability, gaming accessories, and more.

While Nubia and Xiaomi have not yet reached the level: what they renew is mainly towards large frequency displays, increased performance and general upgrades for parts considered gaming.

As for rookie Lenovo Legion: what they want to bring here is a unique and unique design, paving the way for not only gaming but also some of the purposes surrounding it such as streaming.

Stream games on smartphones may be quite popular in China, but the international market and even Vietnam we are still quite unfamiliar with those things.

In terms of gaming support: ZTE Nubia Red Magic and ASUS ROG Phone are the two brands with the most accessories for their machines, and of course they will not be included when buying the device.

Black Shark and Legion, the number of accessories is quite limited. If only talking about machines, the technology that supports gaming is no longer too different, since every machine has a gaming mode in software, the trigger keys L and R, vibration feedback, good grip, quick response,…

But of course, that level of perfection in all aspects is still the ROG Phone!

Vivo iQOO 3 5G This year is not included in this article, as this year iQOO seems more inclined to compete with dumping flagship with Chinese brands rather than gaming.

The evidence is that after many generations of devices, this brand that is considered to be a gaming phone by Vivo still has nothing more than configuration and low price.

They even follow a slim design and have holes for the selfie camera in the screen. With a gaming phone, this design can be considered minimal, as it will affect the screen’s visibility and the ability to dissipate heat.

How about you? If you have a choice, which of the 4 above machines will you choose to play the game? Please leave your comments below the comments!
