National Mobile Upgrades Red Rice Note 4 to Experience

One month later, new products of the red rice series appeared again in front of our eyes. This update is red rice Note 4. From the configuration point of view, it is like a red rice Pro with a single camera.

Packaging, the continuation of the previous style, white carton + phone renderings, but after all, it is strange that the red rice Note 4 on the renderings is the same as the red rice Pro brushed metal process, and we get the sandblasting process version.

Red rice Note 4 has two configurations, namely 2G+16G standard version, priced at 899 yuan, the other is that we have this high version, 3G+64G, price 1199 yuan, both are full Netcom, the screen , SoC, camera, battery and other parameters are exactly the same.

Unpacking is still the structure we are familiar with. There is a matte protective film on the surface of the phone.

Accessories are very standard "two-piece" - power adapters and data lines, of course, card needles and instructions will certainly not be absent.

The power adapter is a 5V 2A standard and its size is relatively small. Unfortunately, it does not support high voltage and fast charging.

Redmi Note 4 uses a 5.5-inch 1080P screen, screen-fitting process is GFF, the screen color from the perspective of view than previous generations have made no small progress.

There is a fluted earpiece on the top, a front-mounted 5 megapixel camera on the right, and a dark gray coloured black front panel also hides the sensor, while the other two versions are symmetrical to the front camera, on the left side of the earpiece.

The bottom is still the three touch buttons commonly used by millet, the default is multi-tasking, home button and return button, we can also personalize the function of the button. The button will have a weak white backlight by default, and the button will not be obvious when the backlight is off.

The front panel of 2.5D is also a very popular design element. The front panel of Redmi Note 4 has little curvature and there is a buffer at the edge of the screen.

The shape of the back and the red rice Pro are in the same vein. The difference is that there is no double rear camera and the back cover of the drawing process.

Rear 13 million pixel camera, dual color temperature LED fill light, there is a press-type fingerprint recognition below.

The rear cover of the Redmi Note 4 is a true all-metal design. Although it is also a three-stage model, the upper and lower sections are also metal. In addition, the nano-injected antenna partition bar is said to use the same technology as the iPhone. Whether or not we use the same technology as the iPhone does not allow us to delve into it, but it feels very smooth to feel it. This is worthy of praise.

In the middle box, due to the use of an integrated metal body, Redmi Note 4 also “customary” added two CNC high-gloss edges, and the cutting is more “simple and violent”, and the two bright edges are wider. It's a little "flashy" feeling.

The top of the fuselage is a standard configuration - 3.5mm headphone jack, infrared sensors, noise reduction microphone.

There are 6 circular openings on the left and right sides of the bottom, the microphone on the left, the speaker on the right, and a micro USB port in the center.

The right side of the fuselage is the volume key and power button.

The left side of the fuselage is a card slot. The red rice Note 4 uses a very common or Cato, while supporting a micro-SIM, while the other side supports a nano-SIM or TF card. In addition, Redmi Note 4 supports blind insertion and the highest downlink LTE Cat.6 network.


Redmi Note 4 comes preloaded with the MIUI 8 system and gives Android 6.0. There is no difference in operation with other Xiaomi series mobile phones.


The first batch of red rice Note 4 used a 1080P screen from Tianma, a 4000mAh battery provided by Desai, and Elpida's 3G LPDDR3 memory. The rear camera is the Samsung S5K3L8 (13 million-pixel ISOCELL), and the front is also the Samsung S5K5E8 (5-megapixel back-illuminated). Of course, different batches of originals may differ and are for reference only.


Redmi Note 4 uses MediaTek Helio X20 processor, the specific model is MT6797, the highest frequency is 2.1GHz, it consists of two A72 with 4 + 4 combination A53, 20nm process. The measured red rice Note 4 can reach the highest frequency of 2.1GHz in daily use, and some A53 cores are often closed in order to save power.


Redmi Note 4 uses a sensor from Samsung or OV. We have this version of Samsung's S5K3L8 sensor. Here are some of its real proofs:

In general, the quality of photographs is quite satisfactory, and it is in line with the standard of this price. As for the advantages and disadvantages of the same type of products, it is necessary to make more in-depth comparisons and tests before they are known.


From the appearance and configuration of Redmi Note 4, it is all aligned with Red Rice Pro, and it has a better price/performance ratio. Compared with the Rednet Note 3 full Netcom version, the two are also close to the configuration, and more is just the difference between style and body design style.
