Jiayu S3 4G LTE Smartphone 13MP Camera performance

Frontal camera gives a very good picture quality even in low light conditions and is able to recognize faces. It will be sufficient for high quality video through Skype or similar program, and for good selfies. But more interesting is the main camera of Jiayu S3. The manufacturer not only equipped it with a famous and high quality Sony Exmor IMX214 image sensor with F2.0 lences, but also installed two LEDs for flashlight, so you can expect better images in low light conditions.

The native camera application does not have a lot of settings, as well as suffers an addiction to incorrect choice of the ISO parameter, so it is best to use a third-party camera program, such as Camera FV-5.The geometric distortions of images are very reasonable, although noticeable. But this disease affects almost all mobile cameras, and most of them – to a much greater extent.

The reasons are the small size of the image sensor, and compactness, simplicity and cost-efficiency of the optical system. On the other hand, images have virtually no chromatic aberrations, which is quite rare for phones cameras. I am not inclined to believe that the lens system is so good that it does not give chromatic aberrations, but they are well treated by the software, and, apparently, the manufacturer paid attention to this problem in the camera drivers. That is a good point. Sharpness in the center of photos is excellent, at the edges, especially in the corners, it is much worse, but, again, this is no crime, as we can observe the same situation in 99% of mobile phone cameras. LED lighting is very bright, compared to most other phones. Two LEDs are not only brighter, but also capture a larger area of the space, not only illuminate forwards.

However, they have the same color. Still, I haven’t notice any serious problems with the white balance. I think the LEDs of different colors in the iPhone is more a marketing feature than a real need. Like it or not, but one, two and even three LEDs will not replace a real Xenon flash. Even an inexpensive simple hand-held camera will show the better results in the dark at the expense of a larger image sensor and better flash. However, the results when shooting in low light with flash are not bad. Without flash,  the image quality in such conditions, as one would expect, leaves much to be desired. In general, the main camera of Jiayu S3 Smartphone more than fulfills its money. I took a few photos with the standard camera application with default settings, as well as several pictures with Camera FV-5 app with a slightly adjust settings.

Jiayu S3 4G LTE Smartphone data transfer and navigation function

Jiayu S3 phone supports two SIM cards, both Micro-SIM. The ranges from the engineering menu for SIM1: GSM 850, 900, 1800, 1900; UMTS 800, 850, 900, 1900, 2000 (which is also 2100; by the way, Jiayu S3 supports more WCDMA ranges, than any of the previous MTK-based phones); LTE Band 3, 7, 20, 38, 39, 40, 41. SIM 2 only supports GSM. You can’t get to the Engineering mode from the Mobile Uncle tools, as usual. Easily solved by downloading programs such as “MTK Engeneering Mode” from Google Play. There are more than one such program – I downloaded the first one. And it works.

I disabled the unused frequencies to save the battery. However, the white frequencies are supported, may be switched on, and they work. The grays are not supported.

First cold start (without Wi-Fi and SIM-card, only by satellites) took about 3 minutes, but the phone was lying at the window on the sixth floor, surrounded by several 10-16 floors buildings. A few minutes later it already saw a dozen of satellites with pretty decent signal level for placing, and all of them were connected. At first, it could not see any of the Glonass satellites, only GPS. However, later the signal from three Glonass satellites has been detected. Generally, in my city there is a signal of 8 (possibly more) Glonass satellites, devices based on Intel and Qualcom processors catch them easily. Perhaps, the second experience with Glonass (the first was MTK6595) is still not so succesfull.However, to say for sure, it is nesessary to test the phone outdoors. Also, the Chinese BeiDou-2 Positioning System is coming. In Kharkiv (Ukraine) I managed to detect satellites #214, and later #210, both with good signal (up to 33 and 36 dB) and the phone even used them to define its coordinates. In general, navigation works without problems, and better than for most of the previously tested devices, not only Mediatek based. Especially, because now Jiayu S3 Smartphone supports three navigation systems, whose satellites are available worldwide.

Connecting to three satellites navigation systems simultaneously. And it is inside the building, near the window:

Jiayu S3 Octa Core Smartphone Sensors and Sound

Next, all sorts of stuff from what I noticed during these two weeks of using Jiayu S3. Touch buttons under the screen have a backlight, but it is rather weak and uneven. The buttons visibility under normal illumination conditions is bad, because they are indicated in gray on black. Under the sun the visibility is much better. Apparently, the paint reflects light. Two microphones are located at the bottom (primary) and upper (noise reduction) edges, but not symmetrical. Lower left, upper right. The sound in the video should be written in stereo, but there may be a slight distortion due to asymmetric arrangement of microphones. In Redmi Note both microphones are arranged symmetrically. ThL 5000 has only one microphone, located on the front panel of the phone, which, from my point of view, spoils the design, but it is likely to have a positive impact on the quality of sound during a telephone conversation.

The distance to the screen from the upper and lower edges is the same. This has a positive effect on the perception of the design, and probably be liked by the gamers – the phone can be rotated, which is especially important when it is charging. On the other hand, the use of touch buttons under the screen is slightly less convenient in normal phone orientation, because it is more difficult to reach them.

Jiayu S3 has quite a lot of sensors: accelerometer, gravity sensor, linear acceleration sensor, gyroscope, light sensor, magnetic field sensor (also known as electronic compass), orientation and proximity sensors. All sensors are working. I have some claims to compass and light sensor. In general, compass works, but sometimes north jumps from its rightful place for a second. However, this is typical of most phones with a magnetic sensor. Better it works only in Xiaomi phones, which also have no problems with GPS, even those based on Mediatek processor (checked with Redmi and Redmi Note). Light sensor operating in the range of from 10 to 9000 lux, maybe more under direct sunlight. However, the lower value sometimes “sticks”.Usually at 100 or 200 lux, but it can get stuck even at 8000. In practice, this would mean that at the entrance from the bright sun into the dimly lit room, for example, the sensor will “forget” to reduce the brightness of the display. However, the sensor does not stop working completely, and if the illumination conditions changes it starts reacting again. Again, this behavior is typical for many phones. I rarely come across the phones, which have acceptable light sensor, and never saw the perfect light sensor. Even the magnificent Redmi Note has the crippled light sensor, which was not cured with any firmware, so it is better not to use it.However, hopes for the future firmware is still there. Jiayu is expected to release at least several updates, and Jiayu phones are almost as liked by rom-makers, as Xiaomi, Lenovo, or Meizu, for example.

Jiayu S3 Smartphone has two main speakers, both working, but I find it difficult to say  in mono or stereo, even after listening to them with “Stereo Test” program. I would say it is rather mono, Ie both speakers are playing the same channel. On the other hand, they are located too close to each other and focused on the vertical using of phone, so it would be difficult to notice stereo anyways. Maybe there is stereo. The quality is decent, but nothing more. Phone speaker also has a good quality, but nothing very special compared to the competitors. There is no background noise from the main speakers, which is very good, because many of the latest phones have this problem (Redmi Note, ThL 5000, Zte V975 and others). I liked the sound in decent headphones (Panasonic RP-HTF890, Coss Porta Pro and Xiaomi Pistons 2 Gold).  Volume level is sufficient, no distortions, bass and treble are in their rightful places. Enough for daily use.

Jiayu S3 4G Smartphone Battery and Screen simple Analysis

On February 11, Jiayu S3 was received from the seller by Singapore Post, and on February 23 it came to my local post office, where I received it on February 25. The box contained a standard set – the phone with the battery, documentation in Chinese, white charging and data transfer cable and white original Jiayu charger 5V and 1A with China (US) plug, as well as an adapter for European sockets. The phone is black, and the accessories are white, a little surprise from Jiayu. You can get somewhat different set. As I have pointed out above, there is English box for this device, and the phone itself, will probably have a different firmware, without Chinese communication frequencies and Chinese programs. In addition, you may receive the charger with different plug, which is suits your sockets.

The screen protector is glued to the screen perfectly, so that it all can be seen only near the front speaker and sensors, without a single speck of dust or air bubbles. This indicates a significantly increased culture of assembly of Jiayu phones and increased degree of automation of the process, which is good.

No issues with build quality, everything is fine here. No squeaks, the gaps are small and smooth; the materials are pleasant to the touch and appearance. The buttons seem to be madefrom metal. The phone is compact enough for 5.5″ screen; it is smaller in all dimensions than Xiaomi Redmi Note with the same screen size. It weighs 159.9 g with battery, Redmi Note is heavier – 199.5 g, the capacity of the batteries in phones is almost equal, Xiaomi is slightly ahead – at least 3100 mAh with typical 3200 mAh, and this is the better way to show the battery capacity, against 3000-3100 mAh for Jiayu.

The device is equipped with a battery, which has a typical for modern 5.5” phone capacity, 3000 mAh. The manufacturer indicates its capacity as “3000-3100 mAh.” In S3, I suppose, we have a typical capacity of 3000 mAh and 3100 mAh maximum capacity. Nevertheless, the results of the battery life test in Jiayu S3 are very close to the results of Xiaomi Redmi Note, despite the fact that Xiaomi has a bit bigger battery, lower screen resolution (720×1280 VS 1080×1920), and less powerful processor MTK6592 1.67 GHz against MTK6752 1.69 GHz for our today’s hero.ThL 5000 in the battery life test shows somewhat better results than Jiayu S3, but it has a non-removable battery with a huge for cell phone capacity of 5000 mAh and a smaller screen (5 inches, but the same resolution as that of the Jiayu S3). Processor in ThL 5000 – MT6592T. It is an overclocked to 2,0 GHz version of the standard MT6592. Despite a higher maximum operating frequency of MT6592T, MT6752 performs much better, which is confirmed by the test results. With Jiayu S3, you can count on 4-5 hours of heavy games, 6-7 hours of simple games, 8-10 hours of video and about the same 8-10 hours for the Internet via WiFi. The book may be read up to 15 hours.Maximum charge current – up to 1A according to a fairly accurate Charger Doctor with a good cable, but can be lower on the warm device (if you actively use it during charging) to protect the battery. Redmi Note and ThL 5000 charged a little faster – up to 1.25 A and 1.3 A, respectively, so here Jiayu lagging behind. Full battery charge can take up to 3.5 hours. Note, that the result will vary depending on the brightness of the large and high-resolution screen. To improve the results you should lower the brightness to the lowest comfortable level. In addition, we can expect the further improvement of the results of battery life with the release of firmware updates, including the previously promised Android 5.0. In general, we can state the fact that Mediatek MTK6752 turned to be a very energy-efficient processor, despite the fact that its performance is increased significantly compared with MTK6592.

Jiayu S3 Smartphone has a very nice and responsive capacitive touch screen supporting 10 simultaneous touches. Accuracy and speed of touches definitions is at the highest level. However, the sensor does not like low-quality chargers. Unlike some other manufacturers, Jiayu does not add filters that allow you to avoid false touches or their losses, when charging your phone with low-cost universal USB charger. There are no problems when charging with the original charger, computer USB port and charger from Xiaomi Redmi Note, but when charging with no-name, but normal quality charger, tested with dozens of different devices, touch sensor starts to react a bit inadequately. Nothing like what we have seen on some devices 2 or 3 years ago, but still. So be warned.

Best smartphone specifications from SpeMall: Jiayu S3

I use the phone for about two weeks now, this phone was purchased in the popular Chinese online store,Spemall, for only $180. The review is devoted to the standard version of the phone with 2GB RAM Jiayu S3 Basic. Just a few days ago, an advanced version of the device went to shops, which differs from the standard version by 3 GB of RAM, and NFC support. It is only slightly more expensive, it is Jiayu S3 Advanced. Now, Jiayu S3 Basic and Jiayu S3 Advanced both are in stock At SpeMall!

Other than that, both devices have the same and very interesting technical specs:
CPU: MTK6752, CortexA53 ARM v8 64-bit, 8 cores, up to 1690MHz
GPU: Mali-T760MP2, 700 MHz
RAM: 2 Gb / 3 Gb
Flash memory: 16 Gb
SIMcards: 2MicroSIMcards
Phone:GSM 850/900/1800/1900MHz, WCDMA 900/1900/2100MHZ + TD-SCDMA, FDD-LTE B3/B7/B20 + TD-LTE
Screen: 5.5 inches, FullHD 1080×1920, IPS OGS
Touchscreen: capacitive, support 10 touches
NFC: supported only in Advanced 3 Gb version of the phone
Cameras: frontal5Mp, back 13 Mp, Sony IMX2141/3.06 image sensor, autofocus and dual LED flash, FullHDvideo.
Dimensions: 152×75.5×8.9mm
Weight: 160 g. including battery
Battery: 3000 mAh
OS: Android 4.4.4, will be upgraded to Android 5.0soon
Language support: a complete set of Androidinterface languages, 60 languages.

Certificate and IMEI of the phone are situated not under the battery, as usual, but on the inside of the back cover. However, there is clearly a regular place for these labels, so it is unlikely that this is a sign that we face an engineering version of the device. Rather, it is, so to speak, a version only for China, because all the inscriptions on the box only in Chinese, except for some abbreviations. A box is made of typical for the latest Jiayu phones inexpensive, but very dense recycled cardboard and it is very similar to the boxes of inexpensive Xiaomi phones.However, we buy a phone, not a packaging. I saw also a slightly different box with fully English specifications. Perhaps it is the “European version” of smartphone, originally running S3W firmware without Chinese communication frequencies. But, it is known, that except the firmware, both versions of the phones are identical. They are identical in hardware, firmwares all mutually compatible, and the “Chinese” version of the device supports all the frequencies, both Chinese and international, which is written on its box, by the way, which lists the 2G (GSM), TD -SCDMA, WCDMA, TD-LTE and FDD-LTE. In addition, phone officially supports Wi-Fi 802.11b/g/n and even ac. Also, box contains the information about the sensor of back camera, and it is a famous Sony Exmor IMX214, and battery with a capacity of 3000 to 3100 mAh. Personally, I do not like such a battery marking. Jiayu should better say it is 3000 mAh, as it is. However, I have no special claims to the battery, considering its capacity, as well as the size of the screen and its resolution, number and frequency of the processor cores. But more on that later.

Speciall Offer from SpeMall: Xiaomi Mi Note

Xiaomi is one of the most important companies of China, and this is something that is evident in the quantity of times that we speak about this manufacturer, and the fact is that rare it is the week that we have no news be already like rumours or an official teaser of a new product with his stamp. The current flagships of Xiaomi and the last phablets that it presented, they were Xiaomi Mi Note and Xiaomi Mi Note Pro, two dispositicos that a design and a hardware have that no smartphone of the company is capable of being equal, and that they mark the new trajectory that Xiaomi wants to have. But today Xiaomi will announce a new product that is possible that it substitutes these two devices.

Xiaomi has grown as the froth in last two years, and that in certain way has been thanks to the incredible and economic prices that they have all his products. At present in his catalogue they have a smartband, several smartphones, a pair of phablets, a tablet, several earphones and many accessories of all kinds, all this with some very good designs and a few really attractive prices.

Since leaving aside all the products that Xiaomi has, we are going to centre on the new one that it will present today, and the fact is that Bin Lin, co-founder of the company, has published in his account of Weibo an image that indicates the presentation of a special edition of the Xiaomi Mi Note.

We do not have any more information on this matter, but yes that we have any idea. Xiaomi Mi Note it has wanted to demonstrate that they can throw devices with very elegant designs, and with a few materials of high quality, from what the new special edition is very probable that it wants to give one more step as for the quality, and the only way that it has of doing it, it being incorporating a crystal layer of sapphire in his later and frontal part.

If this is finally what today the big company China presents, it is something that we will not take in discovering, and throughout the morning we will bring to you the entry with all luxury of details of the new and mysterious version of the Xiaomi Mi Note Smartphone.

Buy a good phone at good price: Kingzone N3 PLUS from SpeMall

At present the mobiles of 64 bits are the protagonist absolute of the market and every time they are more the models that apustan for this characteristic as one of his big props I half-close which to construct the rest of his configuration hardware. There are many very interesting smartphones that they have in his interior chip of 64 bits, so it is necessary to know the possible maxima to know that we are choosing good and deciding on the model that more fits to our needs. The Kingzone N3 PLUS is one of the mobiles of 64 more finished and economic bits and in this post I am going to say to you where you can buy it.

This smartphone is an update of the Kingzone N3 PLUS that we already analyze here a time ago. In this new model some changes have got in the hardware, between which he emphasizes the incorporation of the new chip MTK6732 of 64 bits, but at aesthetic level it is an identical smartphone to the original N3 thing that looks like to me a wise move, since I loved the design of the Kingzone N3 PLUS. The configuration hardware finished of the Kingzone N3 PLUS Smartphone is the following one:

Screen IPS LTPS of 5 inches with resolution HD (1280×720 pixels) with recubrimiento protective Gorilla Glass 3.

Enjoy the beauty of Technology: Cubot S350 from SpeMall

Today almost all the new smartphones that are put on sale are provided with a chip of 64 bits in his interior and this does that the models who lack him lose some interest for the consumer. In spite of this situation and although we all like having the last thing in technology, the true thing is that being realists, for the daily use that we give the majority to our mobiles, a smartphone with chip quad-core MTK6582 is more that sufficient and also cheaper, from what this type of devices are still a good option for those users who know what they want and that do not want to pay for any more than they need. This itself has had to of Cubot thought at the time of creating his new Cubot S350, since MTK6582 and 2 is a question GB of RAM as a phablet with screen of 5.5 inches, chip quad-core.

The specifications of this model are identical to those of Cubot S222 that so much I liked (and the design also reminds me enough to that of this model), with the proviso of which new Cubot S350 incorporates 2 GB of RAM instead of one. This memory extra RAM should improve a little the yield of the mobile when the multitask is weighed and we have many apps in flat second. The configuration hardware finished of Cubot S350 is the following one:

Screen IPS OGS of 5.5 inches with resolution HD (1280×720 pixels).
Processor quad-core MTK6582 to 1.3 GHz.
Dual GPU – core Mali400-MP2 to 500 MHz.
2 GB of RAM.
16 GB of internal storage extendable by means of microSD of up to 64 GB.
Rear Chamber of 13 MPx with Flash LED and autofocus and front camera of 8 MPx. Dual SIM.
Battery of 2350 mAh.
Android 4.4 KitKat.

In the aesthetic paragraph, Cubot S350 Smartphone also reminds me very much to Cubot S222 and the changes are very subtle. In fact, it preserves one of the characteristics that I more liked of the S222, his contained dimensions that turn it into a ‘teeny-weeny’ phablet of 5.5 inches.

King Smartphone from SpeMall: Kingzone Z1

Kingzone is one of Chinese brands that is becoming a good name in the market in recent times. Their smartphones tend to scratch at a very high in most of the sections and besides having designs enough original and attractive, escaping some of the trends of the market, also have a very good build quality and specifications of height for the range to which they belong.

With this formula have already launched several models on the market with considerable success and the last to arrive was his brand-new Kingzone Z1, a smartphone premium high-end chip octa – core MTK6752 of 64-bit and many quality details that make it special. In this post I will tell you where you can buy the Kingzone Z1 with confidence at a good price.

In the introduction I mentioned that this Kingzone Z1 is a model of high-end premium and this is reflected in their specifications, which are the very best that can be found in today’s mobile market with Mediatek processor. The complete hardware configuration of the Kingzone Z1 Smartphone is as follows:

JDI LTPS OGS display of 5.5 inches with HD (1280 × 720 pixels) resolution.
