Huawei Mediapad 10 Fhd Not Turning On

Honestly, Huawei was a little late with the release of this tablet on the market. If he appeared shortly after the announcement (which took place in May), the device would have excellent prospects precisely in the top segment. as one of the first Android tablets with a Full HD class screen. But in the end, the Chinese company lost the lead to both ASUS (Asus Transformer Pad Infinity TF700T tablet) and Acer (Acer Iconia Tab A701 tablet), releasing their device to the Russian market only in October, and in November it appeared (though for now only in the Western market) another powerful competitor: Google Nexus 10. On the other hand, there are still not many tablets with Full HD screens on the market, so the Chinese company’s product will definitely not be redundant.

To understand how the Huawei MediaPad 10 FHD looks like competitors, let’s look at our traditional table.

. according to official manufacturers data
. at the time of writing, the fourth-generation Apple iPad and Google Nexus 10 were not in the official Russian sale, so for them we provide official US without state tax. The price for the iPad is taken for the option with a 3G / 4G module and 16 GB of flash memory; for Huawei, we give the average cost for the maximum possible configuration (3G and 16 GB of flash memory); Acer Iconia Tab A701 shows the average price in Russian retail (according to Yandex.Market) for a model with 3G and 32 GB of flash memory (this is the minimum possible option).

As you can see, against the background of competitors, the Huawei tablet looks very decent, although it raises questions, firstly, the lack of Micro-USB and HDMI, which two other Android tablets have, and in addition, the HiSilicon K3V2 chip is a dark horse. Firstly, there is information on the Web about more powerful versions of the same SoC. with a CPU frequency of 1.5 GHz, but on tablets shipped to Russia, the frequency is only 1.2 GHz. Secondly, the true performance of this SoC is still a mystery to us, despite the approximate compliance with the characteristics of the younger modification of NVIDIA Tegra 3. But we will definitely check it. In the meantime, a complete list of features of the Huawei MediaPad 10 FHD.

Now let’s get to know the tablet better.

Equipment. Design

Comparison of the design of tablets with the iPad is already imposed in the teeth, but in this case you can not do without it: like Apple, Huawei designers preferred an aluminum case, smoothly beveled edges and a minimum of connectors.

The main difference between the Huawei MediaPad 10 FHD is two speakers (by the way, quite loud) on the back side instead of one and a horizontal orientation (labels, camera and speakers are located along the wide side).

In addition, the area covered by a plastic insert on the rear panel (behind it, apparently, there are communication modules) is much larger than that of an iPad with 3G / 4G. On the other hand, the Huawei tablet is thinner by half a millimeter, and its weight is 61 grams less than that of the Apple iPad.

Perhaps it was the desire to make the device as thin and light as possible that influenced the decision not to install Micro-USB and HDMI ports. But there are slots for the SIM card (in the 3G version of the tablet) and microSD covered with a lid. they are located on the upper edge of the device. Nearby is the hole of the built-in microphone.

Both buttons (Power and volume rocker) are located on the right side.

On the left side there is only a headset jack (3.5 mm).

At the bottom there is a dock connector for connecting accessories and a charger. It’s funny that it is 30-pin. like Apple did before. but it is not compatible with Apple, ASUS and Samsung chargers (they also have similar dock connectors). When will standardization come here?

In general, the design of the Huawei MediaPad 10 FHD is mixed. It seems to be similar to the iPad, but, like any imitation, it looks worse than the original. It seems cool that the device is thin and light, but if for this you have to sacrifice the ability to connect flash drives and connect the tablet to an external screen. then I personally am not ready to pay such a price. It’s clear that Apple has the same shortcomings, but you expect more flexibility and openness from an Android device.

And last: build quality. At first glance, it seems good: nothing creaks, the aluminum case looks reliable. But the copy that we had suffered from a strange and very serious drawback: after turning off the screen or device, it was not always possible to turn on the screen again. We tried different ways: connected to the charger, tried to restart the tablet by long pressing and holding the power button, but the result was unpredictable: sometimes it helped, sometimes not. Apparently, the screen is not very well attached to the rest of the components, and this is a lack of assembly. We emphasize that such a situation may indicate marriage of a particular instance. But at the same time, any marriage is an occasion to think about the reliability of the whole party.

Screen

As already noted, the screen resolution (Full HD class, 1920 × 1200) is the main advantage and feature of the tablet. Thus, at the moment it is one of four Full HD-tablets officially presented on the Russian market (we do not consider various modifications of these models).

A detailed examination of other characteristics of the screen using measuring instruments was carried out by the editor of the Monitors and Projectors and TV sections Alexei Kudryavtsev. We give his conclusion.

The tablet screen is covered with a glass plate with a mirror-smooth surface and, judging by the reflection of bright light sources in it, does not have an anti-glare filter. On the outer surface of the screen there is a special oleophobic (grease-repellent) coating, so fingerprints do not appear as fast as in the case of ordinary glass, but are removed more easily.

With manual brightness control, its maximum value was 310 cd / m², and the minimum was 7 cd / m². As a result, at maximum brightness in bright daylight, the tablet can, in principle, be used, but there is no margin of brightness, and the absence of an anti-glare filter further worsens the readability situation in bright light. The minimum brightness will allow you to comfortably work with the tablet even in complete darkness. In reduced consumption mode, the maximum brightness is limited to 220 cd / m². There is an automatic brightness adjustment according to the light sensor (apparently, it is located to the left of the front camera eye). In complete darkness, the auto brightness function reduces the brightness to 50 cd / m², when you switch to the conditions of an office lit by artificial light, the brightness does not change, and in a very bright environment it rises to 270 cd / m² (it was possible to the maximum). In the opposite direction, there is a large hysteresis: when switching to office conditions, the brightness decreases to 150 cd / m², and up to 50 cd / m². only in complete darkness. At low brightness, there is no modulation of the backlight, so there is no flickering of the backlight.

This tablet uses an IPS-type matrix, as a result, the screen has good viewing angles without inverting colors and without significant color shift even with large deviations of the gaze from the perpendicular to the screen. When deviating diagonally, the black field is highlighted, but not very strongly and, depending on the direction, acquires a purple hue or remains close to a neutral gray color. With a perpendicular view, the black field uniformity is generally good, but right next to the edge in several places you can see a slight increase in the brightness of the black field. The response time for the black-white-black transition is 23.4 ms (13.7 ms on. 9.7 ms off). The transition between the midtones of 25% and 75% (according to the numerical value of the color) and vice versa in total takes 35.1 ms.

The contrast is relatively high. 855: 1. The gamma curve constructed from 32 points did not reveal a blockage in either highlights or shadows, and the approximating power-law function exponent is 2.32, which is slightly higher than the standard value of 2.2, while the real gamma-curve deviates somewhat from the power-law dependence ( there is a small blockage in the world):

Color gamut narrower than sRGB:

Apparently, the matrix filters mix the components together. Spectra confirm this:

This technique allows you to increase the brightness of the screen at the same energy consumption for backlight. The color temperature balance is very good. shades of gray have a color temperature close to 6500 K. The deviation from the spectrum of an absolutely black body (delta E) is less than 6 units, which is very good for a consumer device (dark areas of the gray scale can be ignored, since there the color balance does not matter much, and the measurement error at low brightness is large):

As a summary, let’s say the following. The tablet screen does not have an anti-glare filter and cannot boast of a large margin of brightness, which makes it somewhat difficult to work with it in bright external light. The color gamut is narrower than sRGB, but the colors are balanced. In general, the average.

The Huawei MediaPad 10 FHD screen recognizes 10 simultaneous touches.

Game Performance and Support

The tablet runs on a chip of its own production of Huawei. HiSilicon K3V2. We already wrote about the characteristics of this SoC above. The amount of RAM. standard: 1 GB.

So, let’s see what results Huawei MediaPad 10 FHD demonstrated in the benchmarks we traditionally used. We will compare it with Google Nexus 10, ASUS Transformer Pad Infinity and the fourth-generation Apple iPad. But we emphasize that on the Huawei tablet at the time of testing, Android 4.0.4 was installed, while other Android devices had Android 4.1 (ASUS) and 4.2 (Google). This may affect the results, so a direct comparison is not entirely correct.

In Quadrant Standard, the tablet performed worse than Google Nexus 10 and ASUS Transformer Pad Infinity, gaining only 4228 points. Obviously, the loss to the ASUS tablet is due to the lower CPU frequency (1.2 GHz instead of 1.7 GHz), and the lag behind the Nexus 10 due to the older CPU architecture.

In SunSpider, the tablet again showed itself not in the best way, although the gap from Tegra 3 is not so great here.
