The overwhelming majority of modern technology is assembled in huge factories in China, and you can probably slowly forget about brands, unless for you the brand itself is the main reason for purchasing a particular device. Hundreds of devices are manufactured in the same factories, have the same components, similar software, and the difference between them is minimal. And the only thing that matters here is quality, assembly and customer support.
If we talk about components, then in the communicator Fly IQ441 uses MTK6577 processor manufactured by MediaTek. It supplies processors for a huge number of media players, phones and other small electronic equipment, but has not received much recognition in this field. She gained fame after a large number of "clones" of top-end communicators appeared, which many small Chinese manufacturers began to produce and sell. However, over time, quantity turns into quality. And the MTK6577 processor from MediaTek turned out to be quite a worthy product, which was confirmed by tests. But let's not get ahead of ourselves.
Fly IQ441 Radiance.

Appearance and design.
If you look at the communicator Samsung Galaxy S2.
The front panel of the device looks like a combination of the appearance of Samsung smartphones of the first two generations and Motorola smartphones (only the hardware key for returning to the main screen is missing), and the reverse side Samsung Galaxy S2... The placement of design elements and their shape are also the same. Both communicators have the same surface of the battery covers. It has a rough texture of intersecting lines that prevents the smartphone from sliding in the palm of your hand and prevents the appearance of fingerprints.
Fly IQ441 Radiance: rear view.
These devices have almost the same dimensions, but this applies to most modern smartphones (not just Android). Weight at Fly IQ441 more than the competitor, by 20 grams. But this difference in mass is almost imperceptible.
In appearance and design Fly IQ441 actually turned out to be a reference communicator with Google OS. Smartphones of this class have standard sizes and weights, as well as the placement of controls, cameras and connectors on the device body.
For the manufacture of the case, the developers used durable plastic of gray and black colors as materials. The front panel is covered by a protective glass. Have Fly IQ441 the color scheme is perfectly matched. This is confirmed by the number of sold black and gray smartphones with a similar design.
The front panel of the communicator is almost entirely occupied by the display. At the bottom are three backlit touch-sensitive buttons and the main microphone. Above the screen are an additional camera, sensors and a phone speaker.
Reverse side of the case Fly IQ441 represented by a single battery cover. It contains holes for the main camera, speaker and additional microphone. The manufacturer's name "Fly" has a small size and is placed on the device body near the speaker. There are no more inscriptions and identification marks on the case.
Fly IQ441 Radiance: view under the cover.
The back cover can be detached easily. Below it are compartments for a memory card, battery and two SIM-cards of the standard Mini size. The memory card can be inserted without disconnecting the battery, and the battery must be removed to install the SIM cards.
On the left side of the communicator Fly IQ441 there is nothing, and on the right are the power and volume keys.
Fly IQ441 Radiance: side view.
At the bottom of the device there is only a recess for easy removal of the back panel cover, while the headset or headphone and Micro-USB connectors are located on the top.

As a result, there are no complaints about the assembly of the engineers. Dimensions and weight of the communicator Fly IQ441 optimal, as for a device with a screen of 4.3 inches. There are no obvious design defects, such as excessively protruding cracks, backlash, squeaks.
Smartphone ergonomics Samsung Galaxy S2... Secondly, there is no additional button to control the camera.
In general, the appearance of the communicator Fly IQ441 didn't make any particular impression. The design of the device is not much to praise for. The result is a common reference Android smartphone.
Software.
In a smartphone Fly IQ441 the operating system Android 4.0.4 Ice Cream Sandwich is installed without any shell that would change its appearance. On this, the review of the software component could have been completed, if not for two nuances: firstly, the manufacturer of the communicator provided it with a large number of third-party programs, and secondly, support for two SIM-cards has an impact on the operation of the system.
To begin with, it is worth mentioning which applications are included in the standard firmware of the smartphone. Fly IQ441... Most of them are familiar to those who have ever used the Internet and faced social networks.Icons for client programs of the two most famous social networks in the former USSR, such as Odnoklassniki and Vkontakte, are located on one of the main screens of the system. The next screen contains widgets for two other very popular foreign services - Facebook and Twitter. As a result, the new owner of the communicator Fly IQ441 without any problems, he will be able to share his impressions of his new acquisition in all well-known social networks immediately after its first inclusion.
Also in the communicator Fly IQ441 There are several apps from the search and navigation giant, Yandex. Another screen of the operating system is completely occupied by its huge widget, and there are five of these screens in total. The image of the widget displays its capabilities: search, weather, exchange rates, news and icons for downloading some programs. All services are in one place. It is also worth noting that Yandex Search is integrated into the system's notification panel.
There are ivi.ru and SPB TV applications. With the first, you can watch programs and films online for free. The second allows you to watch several TV channels over the Internet.
With the help of the FlyBook library, an interesting approach to the distribution of literature in electronic form has been implemented. You are invited to download the book and read it for free, instead of paying for the purchase. There is only one condition - constant viewing of advertisements at the bottom of the display in the form of a banner. Having parted with an insignificant amount of money, you can get rid of it. Payment is made by sending an SMS message. After downloading, each book is installed as a separate program. Thus, by paying once, you will get rid of advertising, but only for one specific book. To view all the following literary works, you will have to part with money again every time.
There is another interesting program - a client of the uBank.su payment system. Services such as "Webmoney", "Yandex.Money" or "Qiwi" have approximately the same capabilities: withdrawal and deposit of money, payment for various goods and services in the network. There are no complaints about the work of "uBank.su". Transferring funds from a credit card and paying for services are quick and easy. The disadvantage is the absence, both on the system website page and on the program screen, of displaying the amount of cash on the account. It was always equal to zero, but it was displayed correctly in detailed statistics and reports. The working conditions and more detailed features of the service can be found on its page on the Internet.
There are a few other third-party apps worth noting. Voice changer is a program for those who like to call friends and acquaintances and speak in a different voice. All such connections are charged per minute. ES Explorer is a file manager that allows you to manage the contents of the smartphone's memory and connect to remote resources of the local network, exchange information via FTP or Bluetooth. Intaxi is an application for finding and ordering a taxi. CoinKeeper is a personal finance accounting system.
The presence of two slots for SIM-cards determines the presence of a page for configuring their work in the general list of smartphone parameters. Here you can disable each module individually, as well as set the default map for most standard actions: messages, voice calls, video calls and data transfer. Operator names are not displayed everywhere. For example, they are absent in the list of messages and calls, so you can find out which number a particular message came to only knowing which cards are inserted into the SIM1 and SIM2 slots. These uninformative names are displayed instead of operator names. Whenever there is uncertainty about which card to use (if the card is not assigned by default), the operating system offers a dialog with a choice.
Display and sound.
Many people know that IPS screens are installed in Apple equipment. IPhone smartphones are no exception. Fly IQ441 and iPhone 5, apart from the same type of matrix, have approximately the same screen sizes. The difference lies in the screen resolutions: the usual WVGA 480x800 pixels in Fly IQ441 and Retina 640x1136 pixels for the iPhone 5. As a result, the pixel density of the Apple smartphone is 326 ppi, while the communicator from Fly is 218 ppi. Of course, the one and a half difference in pixel density affects the performance of the smartphone. Fly IQ441but this difference is not that important and can be neglected in most cases. This resolution will be enough for a 4.3-inch display. And if we take into account the price of the communicator, then in such an affordable device one can only be glad of such a screen. For example, the ZTE Blade + communicator is equipped with a display with the same dimensions and resolution, has about the same price, but has a noticeably worse matrix than y Fly IQ441 - conventional TFT TN.
Smartphone display Fly IQ441 has good viewing angles, but the protective glass is noticeably glare. Fingerprints remain on it. All this is striking in bright ambient light. Only automatic or manual adjustment of the screen backlight increase helps to solve the problem. The display is equipped with a capacitive touch panel with a maximum number of simultaneous touches - 5. Based on the readings of the position sensor in space, the orientation of the screen changes automatically. This is a common functionality that you won't surprise anyone with these days.
The communicator has a fairly loud main speaker. Thanks to it, you can listen to call signals, alarms and navigator prompts. It does not have the ability to reproduce bass, but you can listen to music. There is no bounce or extraneous squeaks in it.
Communicator Fly IQ441 has a not very loud phone speaker. For outdoor conversations, its volume is slightly below average, but quite sufficient. Using the smartphone indoors did not cause any problems - the interlocutor's speech was clearly audible. There were no problems with the audibility of speech from his (interlocutor) side.
The complete wired stereo headset left a good impression. The sound quality from its speakers was not perfect, but you can still distinguish between the low and high frequencies. The sound gave off a little metal bass at high volume, but, in general, was acceptable for listening to music in transport. The volume of the sound from its speakers is average at maximum power.
The design of the headset is not quite comfortable: the main problem is the very short wire at the left speaker. As a result, the control unit with the call answer button and microphone is very close to the cheek. At the same time, it has a clip for fastening and soft ear pads, which should be attributed to the merits.
Communicator Fly IQ441 has a built-in FM radio receiver, which becomes operational when a headset or headphones are connected. The quality of the radio signal reception is normal. There is a program for controlling the receiver with a clear, concise appearance. It can search for stations by automatically scanning the range. It is also possible to set the required station frequency manually and save it in the list. The unit supports RDS. You can record radio broadcasts in the smartphone's memory. You can also output sound to the main speaker.
Communication and wireless interfaces.
Smartphone Fly IQ441 has two cellular modules, but only one (SIM 1) is capable of working in 3G networks. Standard phone calls and EDGE / GPRS data exchange are available for each of them.
You can switch between SIM cards on the fly, as well as choose which communication module to use to send messages and make calls. The options may vary. Communicator software Fly IQ441 does not restrict the user in any way in the desire to save money on communications and be available for communication in two cellular networks. But there is still a limitation: talking on one line, the other becomes inaccessible.
Depending on network capabilities and settings, data exchange can be performed using EDGE / GPRS and HSPA / UMTS technologies. Most likely, HSPA + is not supported, but exact data on this score are absent both on the website of the communicator manufacturer and on the website of the processor manufacturer.But there are many other smartphones based on this SoC where HSPA + is on the list of their characteristics.
A similar situation with determining the exact parameters of the communicator appeared when familiarizing with the Bluetooth module. The processor developer's website lists version 4.0, and the smartphone manufacturer's website states 3.0. The smartphone supports the following operating profiles: stereo headset (A2DP) and audio connection, wireless modem (DUN), video and audio device control (AVRCP), hands-free headset connection (HFP), object exchange (OPP), file exchange (FTP) , Contact List Access (PBAP), Serial Port Emulation (SPP). With headset connected Fly IQ441 correctly conveyed the names of the tracks, but the time of their playback is not. Incoming calls were presented as numbers, but it was not possible to make a call using the headset itself.
Smartphone Fly IQ441 the Wi-Fi module can work in networks of the 802.11n standard. There were no connection difficulties with the available networks. Wi-Fi hotspot creation and Wi-Fi Direct technology are supported.
The communicator's coordinates in space are determined using information from a GPS receiver, a magnetic field sensor (compass) and a gyroscope. This process is accelerated using A-GPS / EPO technology.
Cameras.
Smartphone video and photo shooting software Fly IQ441 Launches very easily, just swipe to the left on the unlock screen of the device. The camera starts up in a second, another second is needed for the focusing system to operate and take a picture.
The main camera of the communicator Fly IQ441 with a resolution of 5 megapixels takes pictures of 2560x1920 pixels. It has an autofocus system. There is an LED flash near the camera lens (it can also be used as a flashlight). On the front panel of the smartphone there is an additional camera (VGA) with a resolution of 0.3 megapixels.
The camera control program has a simple and intuitive interface, all the elements of which are self-evident, their location and purpose are the same for most communicators. It has few shooting settings: self-timer, resolution, flash operation, shooting mode, digital zoom, exposure compensation and switching between cameras. The autofocus zone is indicated by touching the display, the program itself "aims" and adjusts the focus.
The camera quickly enters video mode. Video is recorded at 720p, 30 frames per second, in 3GP format (Audio: AAC 128 Kbps, Video: MPEG-4 / H.263).
Photos taken with the built-in camera are shown below. The images are of average quality, when you zoom in, excessive data compression becomes visible, which generates digital noise and artifacts.
Battery life.
Smartphone battery Fly IQ441 has a capacity of 1800 mAh. For communicators, this value is above average, but the hardware characteristics of the device are very demanding: a large display and a processor with two cores.
When testing the autonomous operation of the communicator Fly IQ441 The following results were obtained: when reading an e-book with automatic adjustment of the backlight brightness, it worked for 13.5 hours, and in the same test with a fixed display brightness of 50%, the smartphone lasted 11 hours. When playing music with the display off, the device showed an impressive result of continuous work - 41 hours.
| Capacity battery | Mode MP3 | Mode reading | Maximum load | |
| Fly IQ441 | 1800 mAh | 41.5 h | 13.5 h | 5 h |
| Samsung Galaxy S3 | 2100 mAh | 27.5 h | 12 h | 6 h |
| ZTE Blade + | 1500 mAh | 21 h | 16 h | 5 h |
As a result, we can conclude that the MediaTek MTK6577 processor is very "economical" and consumes little power under light loads. Most of the battery charge in your device Fly IQ441 consumed by the display backlight. By choosing the optimal value for the brightness of the screen, you can achieve a significant increase in the battery life of the smartphone.
Smartphone Fly IQ441 also showed a good battery life in normal use: making regular calls using mobile internet and navigation. In this mode, the battery charge lasted for about a day. The minimum operating time of the device from one battery charge was 5 hours. To create the maximum load, all wireless interfaces were turned on, the display brightness was set to high, and the movie was played over Wi-Fi. It should be noted that this mode of operation led to strong heating of the back of the communicator case.
Smartphone battery charge Fly IQ441 is not very fast, it needs about 4.5 hours to fully charge.
Speed and performance.
Contradictory smartphone experience Fly IQ441 is caused by the hardware filling. The positive side, undoubtedly, can be attributed to the powerful MediaTek MTK6577 processor, namely, two ARM Cortex-A9 cores with a frequency of 1 GHz and the PowerVR SGX 531 video core, which are part of it. But the negative indicator here is the small, today, the amount of RAM, which is 512 MB.
In order to find out where among modern smartphones and tablets are MediaTek MTK6577 and Fly IQ441, several system performance tests were done. The results were obtained using Softweg Benchmark 1.03 and are presented in the table:
| Fly IQ441 | Samsung Galaxy S3 | Samsung Galaxy S2 | Samsung Galaxy S | ZTE Blade + | Huawei Honor | |
| OS | Android 4.0 | Android 4.0 | Android 2.3 | Android 2.3 | Android 2.3 | Android 4.0 |
| Cpu | 2x1 GHz | 4x1.4 GHz | 2x1.2 GHz | 1 GHz | 1.4 GHz | 1.4 GHz |
| Total graphics score | 49 | 29 | 34 | 30 | 79 | 75 |
| Total CPU score | 2748 | 4054 | 3261 | 1572 | 3361 | 3201 |
| Total memory score | 399 | 988 | 783 | 647 | 479 | 551 |
| Total file system score | 208 | 468 | 325 | 74 | 296 | 280 |
The Softweg Benchmark Smartphone Fly IQ441 took a place that fully corresponds to its hardware capabilities. The high result in 2D graphics tests is explained by the high processor frequency and small screen resolution when compared with other devices. The performance test of the MTK6577 processor showed that the MediaTek chip lagged behind rivals Samsung and Qualcomm, although not as significant as the difference in the speed of its memory subsystem and competitors.
Smartphone in Quadrant Standard test Fly IQ441 showed a good result, but nothing more. It outstripped the competitors with single-core processors, yielding only to devices from Samsung.
| Fly IQ441 | Samsung Galaxy S3 | ZTE Blade + | Samsung Galaxy S2 | Huawei Honor | |
| Quadrant Standard (more is better) | 2607 | 5601 | 2207 | 3125 | 2171 |
Test results in AnTuTu Benchmark 2.8:
The graphics subsystem test in NenaMark 2.4 showed a value of 23.8 frames per second.
We also tested the playback of video in various formats. A regular player of a smartphone and several third-party players was used. The results are shown below:
| File characteristics | Dice Player | MX Video Player | Staffed video player |
| MKV / 1920x1080 / H.264 / 39.1 Mbps / [email protected] / not | reproduced with tangible delays | reproduced with tangible delays | not reproduced |

| MKV / 640x346 / XviD / 17.5 Mbps / AP @ L3 / AAC | reproduced fine | reproduced fine | reproduced fine |
For comfortable viewing of videos and movies for your smartphone Fly IQ441 they need to be re-encoded with the appropriate resolution for such a screen and a supported codec at the hardware level, for example, XviD. Then the playback speed will be normal in any case, regardless of the player used. But the processor power for software decoding of video in HD quality is not enough for the communicator.
Conclusions.
From smartphone Fly IQ441 positive impressions remained. The communicator is fast, it saves battery power and there are no major problems.The purchase of this device is beneficial from several sides: firstly, it has an attractive combination of price and functionality - a dual-core processor, support for two SIM-cards, IPS-display (WVGA), Android 4.0.4; secondly, the device is officially delivered to the market and has warranty support from the manufacturer. Many competitors of the communicator Fly IQ441 either have displays of lower resolution, or displays with a simple TN-matrix, or have a high price. This model has very few direct competitors. Some of them are smartphones with similar characteristics, which are now on sale, are presented in the table:

Explay Infinity, compared to Fly IQ441, a more economical but more controversial Super AMOLED + matrix. It is supplied to communicators Fly IQ441except for the brand. Highscreen Alpha GTR outperforms Fly IQ441 in everything, but it also costs more - almost a third.
Most of the Chinese communicators have an even better ratio of price and functionality. They can be easily ordered in any quantity from China. Basically Fly IQ441 is the same Chinese communicator, but with an official guarantee and good localization. But when buying a Chinese device in any foreign online store, the buyer assumes all the risk and possible problems. Some consumers are ready to sacrifice reliability for the sake of low cost, while others, on the contrary, when purchasing a device, want to be sure that in which case the device can be replaced without any problems or returned for repair. And each user chooses the option that is convenient for him.
The disadvantages of a smartphone Fly IQ441 include a nondescript design and a small size of RAM.
In the case of a communicator Fly IQ441 you can forget about the brand as such. The front side of the smartphone does not contain any identification marks, so it can easily be confused with Motorola and Samsung smartphones. If you put your smartphone in the case Fly IQ441 and thus cover the “Fly” inscription on the back cover with it, then no one will even be able to find out which device you are holding in your hands.
