Even big companies like Google can be wrong. This morning, a large number of Android smartphone users were greeted with an application error from the tech giant. It’s time to fix it.

OOO “Novotrand” UNP 193498963 Registered on 25/01/2021 by the Minsk City Executive Committee In the Trade Register since 08/02/2021 Legal entity. Address: 220040, Republic of Belarus, Minsk, Maksim Bogdanovich st., 155, room 301A

Over the past year, Xiaomi, as usual, has released a large number of various smartphones, confused users with renaming and repositioning the lines and promised to revise the pricing policy for its top-end devices, which was not slow to affect the Mi Note 10 Pro, which appeared in the official Russian retail for unprecedented Xiaomi 45 thousand rubles, and later on the flagship Mi 10.

But still, no matter how the manufacturer tries to turn the tide, in the minds of millions of users, Xiaomi products are strongly associated with an affordable price. And it’s good that this is still true: Redmi Note 8T is just one of the very affordable smartphones, the price of which, moreover, has managed to drop noticeably in a few months. What this inexpensive mobile device with five cameras and NFC support is capable of, we will consider in this review.


Redmi Note 8T is equipped with an IPS-display with a diagonal of 6.3 inches and a resolution of 2340 × 1080, covered with Corning Gorilla Glass 5. Physical dimensions are 67 × 146 mm, aspect ratio. 19.5: 9, dot density. 409 ppi. The bezel width around the screen is 4mm at the sides, 5mm at the top and 9mm at the bottom, the bezel is wide for today.

The front surface of the screen is made in the form of a glass plate with a mirror-smooth surface, resistant to scratches. Judging by the reflection of objects, the anti-glare properties of the screen are better than that of the Google Nexus 7 (2013) (hereinafter simply Nexus 7). For clarity, here is a photo in which a white surface is reflected in the turned off screens (on the left. Nexus 7, on the right. Redmi Note 8T, then they can be distinguished by their size):

The screen of the Redmi Note 8T is noticeably darker (the brightness in the photos is 104 versus 114 for the Nexus 7). The doubling of reflected objects in the Redmi Note 8T screen is very weak, which indicates that there is no air gap between the layers of the screen (more specifically, between the outer glass and the surface of the LCD matrix) (OGS type screen. One Glass Solution). Due to the smaller number of boundaries (such as glass / air) with greatly different refractive indices, such screens look better in conditions of intense ambient light, but their repair in the case of cracked outer glass is much more expensive, since the entire screen has to be changed. On the outer surface of the screen there is a special oleophobic (grease-repellent) coating (better than Nexus 7 in efficiency), so fingerprints are much easier to remove, and appear at a slower speed than in the case of ordinary glass.

With manual brightness control and with a full-screen white field, the maximum brightness value was about 470 cd / m² under normal conditions, and in very bright light it rises to 630 cd / m². The maximum brightness is very high, and given the excellent anti-glare properties, the readability of the screen should be good even on a sunny day outdoors. The minimum brightness value is 1 cd / m², so in complete darkness the brightness can be lowered to a comfortable value. In the presence of automatic brightness control by the light sensor (it is located to the right of the cutout of the front speaker, very close to the top edge of the front panel). In automatic mode, when the ambient light conditions change, the screen brightness both increases and decreases. The operation of this function depends on the position of the brightness adjustment slider: with it, the user can try to set the desired brightness level in the current conditions. If you do not intervene, then in complete darkness, the auto-brightness function reduces the brightness to 7.5 cd / m2 (low), in an office illuminated with artificial light (about 550 lux) sets it to 100 cd / m2 (normal), and conditionally in direct sunlight the brightness reaches 630 cd / m² (maximum, this is how it should be). We slightly increased the brightness in complete darkness and for the above three conditions we got 15, 120 and 630 cd / m², this result was fine for us. It turns out that the automatic brightness control function works adequately and allows the user to customize his work for individual requirements. At any brightness level, there is no significant backlight modulation, so there is no screen flicker either.

This smartphone uses an IPS-type matrix. The micrographs show the typical IPS subpixel structure:

For comparison, you can see the gallery of micrographs of screens used in mobile technology.

The screen has good viewing angles without significant color shift, even with large gaze deviations from the perpendicular to the screen, and without tint inversion. For comparison, here are the photos in which the screens of Redmi Note 8T and Nexus 7 display the same images, while the brightness of the screens was initially set to about 200 cd / m², and the color balance on the camera was forced to 6500 K.

Note the good uniformity of brightness and color tone of the white field.

The colors on the screen of the Redmi Note 8T have a slightly higher saturation than natural, the color balance of the Nexus 7 and the tested screen is different. The photo was taken in the case of the Auto profile in the screen settings:

In the case of the Saturated profile, there are no noticeable differences from the Auto profile, and when the Standard profile is selected, the color saturation is slightly less and the color balance changes slightly:

Now at an angle of approximately 45 degrees to the plane and to the side of the screen:

It can be seen that the colors did not change much on both screens, but on the Redmi Note 8T the contrast decreased to a greater extent due to the strong highlighting of black.

The brightness at an angle at the screens decreased (at least 5 times, based on the difference in exposure), and decreased approximately the same. The black field is strongly lightened when deviated along the diagonal, but remains conditionally neutral gray. The photos below demonstrate this (the brightness of the white areas in the direction perpendicular to the plane of the screens is the same!):

When viewed from a perpendicular view, the uniformity of the black field is excellent:

The contrast (approximately in the center of the screen) is high. about 1160: 1. The response time for the transition black-white-black is 21.5 ms (10 ms on, 11.5 ms off). The transition between gray tones of 25% and 75% (based on the numerical value of the color) and back takes 38 ms in total. The gamma curve, plotted using 32 points at equal intervals in terms of the numerical value of the shade of gray, showed no blockage in either the highlights or the shadows. The exponent of the approximating power function is 2.18, which is close to the standard value of 2.2. In this case, the real gamma curve slightly deviates from the power dependence:

This device has a dynamic adjustment of the backlight brightness with an unobvious dependence on time and on the nature of the displayed image. As a result, the obtained dependence of brightness on the hue (gamma curve) may not correspond to the gamma curve of a static image, since the measurements were carried out with sequential output of gray shades almost on the entire screen. For this reason, a number of tests. determining the contrast and response time, comparing the black illumination at angles. we carried out (however, as always) when displaying special templates with a constant average brightness, and not single-color fields across the entire screen. In general, such a non-switchable brightness correction does nothing but harm, since a constant change in screen brightness can at least cause some discomfort.

The color gamut in the case of the Auto profile is slightly wider than sRGB:

When you select a profile, Standard gamut shrinks to the sRGB borders:

The spectra show (Auto profile) that the matrix filters moderately mix the components together:

At the same time, the humps of green and red are relatively well separated, which leads to some broadening of the color gamut.

By default, the color temperature is high, about 8500 K. However, in this device, when the Auto profile is selected, it is possible to correct the color balance by adjusting the hue by a dot on the color wheel or by choosing preset options. In addition, the correction is performed automatically when you select the Standard profile.

The result in the latter case is good (see graphs below), since the color temperature becomes close to the standard 6500 K, and the deviation from Spectra of absolute black body (ΔE) on most of the gray scale is below 10, which is considered a good indicator for a consumer device. At the same time, the color temperature and ΔE vary little from shade to shade. this has a positive effect on the visual assessment of the color balance. (The darkest areas of the gray scale can be ignored, since the color balance there is not very important, and the error in measuring color characteristics at low brightness is large.)

In the settings, you can reduce the intensity of the blue component:

In principle, bright light can disrupt the circadian rhythm (see the article about the iPad Pro with a 9.7-inch display), but everything is solved by adjusting the brightness to a comfortable level, and there is absolutely no distortion of the color balance, reducing the contribution of blue meaning.

To summarize: the screen has a very high maximum brightness (630 cd / m²) and has excellent anti-glare properties, so the device can be used outdoors without any problems even on a sunny summer day. In complete darkness, the brightness can be lowered to a comfortable level (down to 1 cd / m²). It is also acceptable to use the mode with automatic brightness adjustment, which works adequately. The advantages of the screen include the presence of an effective oleophobic coating, no air gap in the layers of the screen and no visible flicker, high contrast and excellent uniformity of the black field, as well as close to sRGB color gamut and good color balance (after choosing the desired profile). The disadvantages are the low stability of black to deviation of the gaze from the perpendicular to the plane of the screen. Taking into account the importance of characteristics for this particular class of devices, the screen quality can be considered high.

Review of inexpensive smartphone Redmi Note 8T

Appearance and usability

Redmi Note 8T did not receive an expensive design, this smartphone with a very simple body geometry, a plastic side frame and completely flat front and back panels looks exactly for its money, does not look more expensive than its level.

In the hand, a smartphone, even with such a chubby and rustic body weighing 200 grams, would be well held due to the wide side edges, which, thank God, did not narrow down here. However, the smartphone still turned out to be very slippery, because the plastic of the side frame is smooth and glossy. Why there is gloss is completely incomprehensible. The sides had to be made matte, non-marking and non-slip.

The block of four cameras at the back sticks out noticeably beyond the surface, so the smartphone does not lie stable on the table. The fingerprint scanner is located here, on the back, there are no complaints about it.

The front camera is hidden in a waterdrop-shaped notch in the screen. It takes up very little space, but there are users who are unnerved by even such a small cutout. But the fact that the device does not have a light indicator for notifications is a huge disadvantage. Especially considering the IPS screen.

The side buttons do not differ tactilely, but are well located on one sidewall, have a pleasant springy travel, there are generally no complaints about them.

The design flaws are partially compensated for by a three-slot tray, in which you can simultaneously put two Nano-SIM cards and a microSD memory card. Hot swappable cards supported.

At the bottom there is a speaker, microphone, USB Type-C connector and 3.5 mm audio output for headphones.

At the top there is an additional microphone and an IR transmitter. Among the preinstalled programs there is a Mi remote control for emulating the remote control.

Redmi Note 8T comes in three colors: white, blue and black (Moonlight White, Starscape Blue, Moonshadow Gray). The smartphone case did not receive full protection from dust and moisture.

Redmi Note 8T. the owner of the so-called “quad camera”, as it is now customary to call smartphones with four rear modules. However, two modules (with the same characteristics. 2 Mp, 1 / 5.0 ″, 1.75 μm, f / 2.4) are used only for measuring the depth of the scene and macro photography, so, in fact, there are only two main working modules. main and wide-angle, without telephoto.

The settings include manual, auto-HDR, panoramic, portrait, night, and slo-mo. There is no native ability to save images in RAW, but you can use third-party programs for this.

The main camera has a 48-megapixel Sony IMX586 module (1 / 2.0 ″, 0.8 μm) and an f / 1.8 lens with a 79.4 ° field of view. There is PDAF phase detection autofocus, but no optical stabilization. By default, the camera shoots at a resolution of 12 megapixels with binning function (intelligent combining of 4 pixels in 1), and the maximum resolution mode of 48 megapixels is very convenient to turn on right from the mode carousel without having to go into the settings. We now see smartphones with 48-megapixel cameras very often, experience has been accumulated, and I must say that Redmi Note 8T is not the worst among its classmates. Small details in 48-megapixel photographs cannot be seen, they always turn out to be blurry, a little fuzzy. And a direct comparison with 12 Mp shots shows that 48 Mp shots are not more detailed. Accordingly, there is no reason to shoot in this resolution, as it only “makes the picture heavier”.

My aquamarine beauty

Good day, dear readers.

Finally, I became the owner of Xiaomi Redmi note 8 pro and I want to share my impression with you. I love Xiaomi with all my heart, well, honestly, well done Chinese. The phone of this company is the third in my account, the first two were Redmi note 4.

RAM: 6 GB.

Built-in memory: 128 GB.

Main camera: 64 Mp 8 Mp (viewing angle 120 degrees) 2 Mp (macro lens) 2 Mp (depth sensor).

Front camera: 20MP.

Optional: rear fingerprint sensor, Face Unlock, one-color LED notification indicator.

Battery: 4 500 mAh, fast charging Quick Charge 4.0.

redmi, smartphone

The phone is packed in a standard Xiaomi box made of white thick cardboard with an orange company logo.

redmi, smartphone

On the top there is a phone, on the side information about the phone and a bunch of all sorts of barcodes.

  • Telephone
  • Silicone Case
  • SIM card slot opener

The appearance is solid, no worse than the flagships. The display occupies 91.4% of the area, so the bezels are very narrow. The corners of the smartphone are smooth, as if streamlined. I really like this stylish design.

The color of the panel is green (Forest Green), as I saw, I immediately fell in love. The deep, dark turquoise color that shimmers is pleasing to the eye. Unfortunately, the photo cannot convey all this beauty. The manufacturer allows you to choose a color from three offered: pearl white, graphite gray and turquoise. Smartphone body from durable 3D glass (Corning Gorilla Glass 5).

On the right side there are metal buttons for blocking and volume control, it is convenient to press them. The front camera is located in a waterdrop notch. On the back are cameras and a fingerprint scanner. To be honest, it is not very convenient that the scanner is located directly under the camera. Firstly, you can slap the camera, and secondly, it’s just inconvenient to get your finger on the scanner. Cameras, by the way, drink decently over the body.

Below is the microphone, charging connector and audio output.

The smartphone is quite large, with a 6.53-inch display diagonal. Although when compared to the Redmi note 4, it is not much larger, but due to the narrow bezels, the difference seems to be significant. At first it was unusual, but already like a dear) From my miniature hands, by the way, it does not slip.

IPS display, with a resolution of 23401080. The color rendition is excellent, the colors are bright and saturated.

This is one of the main advantages of Xiaomi Redmi note 8 pro. The smartphone has four cameras, three on the back, one on the front.

The photos come out crisp and bright, not like those on the old phone. There is a macro mode, a wide-angle view, a portrait.

The front camera is pretty decent too, at 20 megapixels. Selfies are so clear you can see fine details.

The battery lasts a long time thanks to the 4,500 mAh battery. I have enough for about two days, with an average workload of the phone. Although, over time, it will probably hold less, as is usually the case. The phone charges very quickly, it’s not for nothing that the manufacturer provided Quick Charge 4.0.

By the way, I liked the Type-C connector much more than the micro-USB. The most important thing is that the connector fits into the socket the first time, it does not need to be turned back and forth to insert. And there is less chance of damaging contacts.

The phone is just magical. The price-quality ratio is high, as is always the case (well, or almost) with Xiaomi. The design is pleasing to the eye, the color is simply awesome, I admire every minute 🙂 The smartphone just flies, opens applications in an instant, sites are loaded with lightning speed. The fingerprint scanner works well, however, as I wrote above, it is located next to the camera, which is not very convenient. But I think I’ll get used to it over time. There is a face recognition function, but I do not use it.

I really like that the battery lasts for a long time, otherwise the phone usually sits down at the most inopportune moment.

The manufacturer acted very wisely that he added a silicone case to the package, since while you wait for it from Aliexpress, you can lose your phone too 🙂 By the way, I liked the plug for the charging socket.

One of the biggest advantages I consider the presence of NFC, neither Redmi note 4, nor Redmi note 7 had it. When choosing a phone, it was very important to me. Tired of paying with a card, then you can’t find it in your wallet, then you put it somewhere, and then once you paid with your phone.

What else I like about the phone is the presence of the “Mi Remote” application (infrared port). After all, it is very convenient when the remote control for the TV, air conditioner and other devices are always at hand.

I honestly do not understand too expensive phones, this smartphone has everything I need and even more. I see no reason to overpay for the brand.

I am very, very happy with the phone. I recommend to all! I give you a solid five.
