Mobile phone htc desire 816 dual sim. Mobile communication technologies and data transfer speeds

Many well-known mobile device manufacturers are trying their luck in the phablet market: Samsung, LG, Sony, HP, etc. Samsung first released a smartphone with big screen- . The idea turned out to be successful - there was a demand for the new product. Since then, competing companies have been trying to attract customers with their interesting designs, increased performance, additional functions etc. Let's see what HTC offers us.

Processor and memory HTC Desire 816

Base for HTC smartphone Desire 816 became Qualcomm Snapdragon 400 SoC (system on chip) with 4 cores running at maximum load at a frequency of 1.6 GHz. The performance of the integrated Adreno 305 GPU is approximately 2 times higher than the performance of its predecessor, Adreno 225.

The amount of RAM is 1.5 GB, flash memory is 8 GB. At the same time, almost half of the built-in memory is occupied installed applications. The situation can be corrected by adding external memory up to 128 GB. HTC developers did not repeat the mistakes of many of their competitors and equipped the smartphone with a slot for a microSD memory card.

The HTC Desire 816 smartphone runs Android 4.4.2 KitKat OS with the HTC Sense interface. HTC BlinkFeed's user-friendly desktop is packed with features quick access to your favorite sites and offline reading, which will allow you to always be up to date with news on friends’ blogs and in the world.

HTC Desire 816 display and cameras

The display of the HTC Desire smartphone with a diagonal of 5.5" and a resolution of 1280x720 px is covered with protective glass, the creation of which saved on anti-reflective and oleophobic coating. In addition, there are questions about the mechanical strength of the glass: it is easily covered with scratches and fingerprints, and the anti-reflective coating quickly wears off. Super LCD-2 technology, which is used to create the TFT IPS matrix, provides natural color reproduction and pure white color, but does not increase brightness in sunlight. Accordingly, the smartphone screen goes blind in the sun.

The rear 13-megapixel and front 5-megapixel cameras of the HTC Desire 816 smartphone are based on a BSI matrix. Backlight technology provides high light sensitivity, respectively, excellent quality images and low noise levels even in low light. Both cameras can record video in 1080 px resolution.

Housing and communications design


The main frame of the HTC Desire 816 smartphone is made of matte plastic. The rounded corners of the case and the edges of the rear panel visually make the phablet thinner and more elegant. Fingerprints are clearly visible on the glossy plastic from which the rear panel is made. In addition, the smooth tire easily slides in the palm of your hand, which, combined with the substantial size of the device, becomes a significant drawback.

At the top of the front side of the HTC Desire 816 smartphone there is one of the stereo speakers, a camera, light and proximity sensors, as well as led indicator received messages. At the bottom of the front panel there is a second stereo speaker and the main microphone.

The main camera and single LED flash are located at the top of the back panel. The developers placed the power button and volume rocker key on the left side of the case, with the lock button located above.

On the right side there are slots for SIM cards and a card microSD memory, covered with a plastic plug. The plug is held in place by a rubber strap. The HTC Desire 816 smartphone is available in 2 modifications - with and without support for Dual SIM. The card in the 1st slot works in WCDMA/GSM networks, in the 2nd slot - in GSM networks.

On the top edge there is a 3.5 mm headphone jack and a second microphone for noise reduction. You can also use it to record stereo sound for video. The microUSB slot is located on the bottom edge.


Buyers note powerful rich sound from stereo speakers, excellent quality of pictures taken by both cameras, high performance and good color rendition of the image on the display. The HTC Desire 816 smartphone works well as a navigator - it quickly finds satellites and keeps a stable connection.

Many people don't like the small volume internal memory, accessible to the user, and the inability to remove pre-installed applications that eat up this memory. The glossy plastic on the back panel, which collects greasy fingerprints, and the insufficient anti-reflective coating on the protective glass are disappointing. The battery drains faster than the developers promise. The maximum energy saving mode helps to partially solve the problem.

The case is completely non-separable, but nice. Monoblock, in a word. It will suit both brutal men and beautiful women different ages. There are a wide variety of body colors, so everyone will find an option to suit their taste. The smartphone turned out to be very thin and therefore very pleasant to hold in your hand. The weight of the smartphone is 165 grams, which is an acceptable figure for such considerable dimensions. Depending on the color of your HTC, the cover may be glossy or matte.

Shell

It is convenient in many ways; its own shell is installed here by default. Out of the box you get Sence 6.0. All necessary applications are preinstalled, including office, file manager and other software. Again, by default the device is sold with Android 4.4.2. I have no information about whether there is a 5.0 version for it. The smartphone does not have any interesting features, just ordinary workhorse, everyone is here.

Specifications

  • CPU

    MediaTek MT6592, 8 cores 2000 (MHz)

  • Video processor

The hardware has become more powerful compared to the old 816 model. The processor is now different and runs on up to 8 cores. The video chip has also been improved. Productivity only benefited from these manipulations, which means you and I also benefited. After all, in the end, a very productive and interesting device was released.

Memory

There is microSD support, which is good, you can expand up to 64 GB, which is quite enough, even with a margin, I think. Random access memory only 1 GB, for an Android device of the 21st century, today, this is not enough, considering that its predecessor had 0.5 GB more. There are problems with the built-in memory; the smartphone has 8 GB of it, but less than 4 GB is free. You can’t put games on a memory card, so it’s unlikely that gamers will play around with 3.5 GB of memory, roughly speaking.

Connection

Some of you will like it, some of you probably won't, but the smartphone works with 2 nano-SIM cards. This is HTC's policy, so you'll have to put up with it and change your microSim (if you have a SIM card of this format) to NANO! Another disappointment is the lack of LTE support. There is only one radio module in the smartphone. Well, finally, I’ll tell you how bad this smartphone is in the GPS test, in 15 minutes, the smartphone was barely able to see 10 satellites and only took 4 to work. A smartphone is not suitable as a navigator.

Satellite navigation:

GPS(Global Positioning System) is a satellite navigation system that provides measurements of distance, time, speed and determines the location of objects anywhere on Earth. The system is developed, implemented and operated by the US Department of Defense. The basic principle of using the system is to determine location by measuring distances to an object from points with known coordinates - satellites. The distance is calculated by the delay time of signal propagation from sending it by the satellite to receiving it by the antenna of the GPS receiver.
GLONASS(Global Navigation Satellite System) - Soviet and Russian satellite navigation system, developed by order of the USSR Ministry of Defense. The measurement principle is similar to the American system GPS navigation. GLONASS is designed for operational navigation and timing support for land, sea, air and space-based users. The main difference from the GPS system is that GLONASS satellites in their orbital motion do not have resonance (synchrony) with the rotation of the Earth, which provides them with greater stability.

Released in September 2014 new smartphone- HTC Desire 816 Dual. Reviews about it are mostly laudatory. It was hard to imagine that for 16,000 rubles (the average sales price in the year of production) you could buy an excellent gadget. However, this is true. The model quickly became popular. And deservedly so, as it has many advantages. Not without its shortcomings. But, according to most owners, they are insignificant. These and others no less important points will be described in the article.

HTC Desire 816: model review

This device has large dimensions: 156.6 × 78.7 × 7.9 mm. With such dimensions, it weighs 165 g. It is worth noting that it is well felt in the hand. The body is made of plastic with a glossy finish. Fingerprints do not remain on it. At first glance it may seem that back cover removable. However, it is not. It is one-piece, so it cannot be removed. For this reason, the manufacturer placed slots for SIM and memory cards on the right side. The device supports two SIM cards, Nano type. Therefore, it is recommended that buyers contact the salon before purchasing. mobile communications to trim a SIM card to the required format or replace it. Memory card type - micro SD. The device supports up to 128 GB.

Many buyers thought that the device was waterproof because of the solid body. We will have to upset them, since he does not possess such properties. The location of the on/off button and the volume rocker has become somewhat unusual. They are on the left side. However, there are buyers who liked the innovation. At the top there is a standard headphone jack, at the bottom for connecting a USB cable and charger.

The model is available in several colors. When purchasing through online stores, you need to pay attention to the labeling. For example, HTC Desire 816 (White) indicates that the body of the device is white, Black - black, Gray - gray (graphite).

There are no usual control buttons. They are located on the screen. However, the owners are not against this decision, since the screen is large. The frame is narrow. The speakers are installed symmetrically - at the top and bottom. In the left corner is the front camera.

Equipment

The device is packed in a white box. She looks quite stylish. On the front side there are phones with different body colors. In order to understand which one is in the box, you need to look at the information on the side. The name and color will be printed there. For example, HTC Desire 816 (Grey), which means the smartphone is gray.

Under the top cover lies the phone itself in a special recess. Under this panel there is a headset, Charger and instruction manual.

Speaker reviews

The first thing I would like to pay attention to is the volume of the device. The HTC Desire 816 Dual Sim speakers are one of the most strengths. Not even all expensive flagships can boast such a sound. Many buyers note excellent playback of music tracks through headphones. The device also has a stereo effect function. However, its use, as they say, is not for everyone; most people complain that the sound begins to “put pressure on the ears.”

We can’t remain silent about BoomSound. This option is designed to improve the sound. Opinions about her were divided. Some owners of this model claim that without this mode the sound is reproduced much clearer. In any case, the volume of the speakers is at the highest level. While watching movies on your phone, it feels like... home theater. Most people argue that setting the volume to more than 70% is unrealistic, as you begin to experience discomfort.

Reviews about the screen

Many buyers also consider the screen of the HTC Desire 816 smartphone to be an advantage. Reviews from particularly demanding owners say that its resolution is not enough; such devices with a 5.5" diagonal must be equipped with at least Full HD format. However, in reality, not everything is so bad. During operation, the display showed itself to be good: excellent color rendition, saturation, image quality corresponds to more expensive smartphones. Display type - Super LCD 2 (1280×720), capacitive. The number of pixels per inch is 267.

In general, buyers were satisfied with the screen. The only thing you need to be prepared for is the absence protective glass. Given the large diagonal, the owners of this model are advised to immediately purchase a case. Stores also sell protective stacks; they can be purchased separately.

HTC Desire 816: camera reviews

The device is equipped with two cameras: the front resolution is 5 MP, the main one is 13 MP. The quality of the images is excellent, especially considering the cost of this model. Many buyers were surprised by this. Cameras have big set settings, the main one has a flash. The video recording resolution is 1920×1080 pix. There are several types of shooting: 60 frames per second, slow motion, etc. There is no noise in the pictures, no grain. The color rendering is somewhat saturated, but this is a matter of taste.
