This time we have the Nubia M2 (NX551J), a phone presented in a relatively large white cardboard box. The logo is screen-printed in gold on the upper part. In the lower area, the characteristics appear with the “CE” (European Conformity) logo, which indicates that it meets the standards of the European community to be sold here.
The terminal is at the top left. On the right is a box with a red type-C micro-USB cable, a Chinese 5V and 2A output charger (so we’ll need a European adapter), and some headphones.
If we remove the device, we find another box that adds a user guide, the key for the card slot, and a relatively rigid transparent TPU case so as not to have to buy it separately.
Design and Screen
This Nubia M2 looks very similar to other devices of the brand. It is a phone made of a metal alloy which gives it an exquisite look (even though, in this case, it is a black and gold unit). It measures 75.9 mm high x 154.5 mm long and is only 7.0 mm thick, weighing 168 gr. It is a unibody phone that cannot remove the battery.
The screen is 5.5″ AMOLED with 1080 x 1920 pixels resolution. It has Corning Gorilla Glass and a 2.5D rounded glass screen to prevent scratches. In this case, it has a density of 401 pixels per inch. The usable screen area is 71% and has an aspect ratio of 16:9. The color quality is good, but the screen’s brightness could be improved since, in full sun, you have to look for a shadow and strain your eyes a lot.
The phone has symmetrical bezels at the top and bottom. The camera is above, and in the lower area, it has the navigation buttons, and in whose center it has a fingerprint sensor that works as a “Start” button. This sensor is exact, and unlocking is practically instantaneous. It should be noted that it does not have notification LEDs except for the LEDs that light up on the buttons (which are red). These cannot be configured for notifications.
The rear area has a smooth metallic finish: the dual camera and a small flash at the top left (horizontally) free everything else. In the center is the Nubia logo.
Unlike most phones of Chinese origin, which I did not like, the left side has the volume up and down buttons, and on the right side are the on and off switch and the SIM card slot. In this case, two nano-SIM cards can be added, or a micro-SD memory card can be included instead of one.
Below it is the speaker, microphone, and micro USB type C cable slot. It also adds the 3.5mm Jack connector for the headphones, leaving the upper part completely clean.
Power and Hardware
This Nubia M2 has a Qualcomm Snapdragon 625 MSM8953 Octa-core processor (8 cores) that works at 2 GHz speed. It is a processor with various ARM Cortex-A53 structures and a Qualcomm Adreno 506 graphics card with a maximum speed of 650MHz. In addition, the two existing versions add 4GB of RAM.
And to check the overall performance, I have submitted it to the AnTuTu application, which allows a more objective comparison of the different phones, and the result has been 76,517 points. So it indicates that it is a mid-range phone.
In daily use, I haven’t noticed any performance issues, and the messaging apps, social media, and browser all worked fine, but with a little lag when switching between apps (this is the most significant difference in speed between a range of high and a mid-range). On the other hand, when playing multiplayer games, there is a little “lag” or delay when loading the games, which is why it is not the best device for this activity. After playing for 30 minutes, the phone has gone from 28ºC to 38ºC, heating up in the upper back.
It has a space of 128 GB of storage. If we do not consider the space occupied by the operating system and the applications installed, we are left with approximately 104GB for our use. But in addition, it also supports a mico-SD card to be able to expand the storage space.
The sound is pleasing. After measuring with a sound level meter app, I got a maximum of “80 DBS” with the ringtone. Even so, I would not say I liked the speaker’s location since it covers the entire output when you grab it to play.
