Without reliable configuration, 2GB RAM as Lenovo products, Video Explainer Kit Asus but still noticeable by popular brands, technology Super AMOLED screen, support for high-speed 4G LTE network. So this is still a concern in the smartphone segment 3 million.
Video Explainer Kit still share the same design as the cheaper products ever made by Samsung as the rounded edges, shiny chrome rims is a physical home button and two navigation keys below the display. Only a little part dorsal difference thanks to a fake leather like on the Note 3 and Note 4 dorsal part I love this because no grip when holding long dominated by sweat, fingerprints and scratches well limit better. Thanks to the screen size of 4.7 inches of moderate to handle or use the machine very comfortable, but still exists the common drawback of the Galaxy line as part galvanized metal frame easy peeling after a period of use, the camera clusters error. Competition point of cheap smartphone is in the other elements I will say in the following sections.
Not equipped with HD displays as many competitors in the segment, but Samsung has lovingly compensate equip Video Explainer Kit inch Super AMOLED panel with qHD resolution (540 x 960 pixels), so that the possibility J2 visibility remains very good in the price range. As to modes of J2 outdoor screen brightness than most other products thanks to the advantages of technology panels when the sun is pretty intense so can still look good the content, in the distance used generally look very close, then see pitting.
When compared with the new Alcatel Flash 2 they have the opportunity to experience the screen recently J2 better color reproduction and brightness is much higher, although his previous comparison with the Video Explainer Kit Laser and brightness of the Flash 2 won. Thus can be seen but not as high resolution as rivals but quality is not inferior, also talked about the possible brightness beats many competitors in this segment of less than 4 million.
When placing the outdoor screen mode J2 very bright Galaxy
It should also be noted when using Youtube machine application only supports a maximum resolution of 480p, a limitation with you like watching videos online. With his personal use smartphones primarily for surfing Facebook, read the newspapers, nothing too complain.
Video Explainer Kit preinstalled Android 5.1 version Lollipop can say is the very latest on the cheap products. Customizable interface Touch Wiz machine remains Samsung's familiar but not so high should configure applications and utilities that came to be omitted and still more limited.
There is a feature that I liked in J2 is capable of opening fast camera that I have experienced on Galaxy S6 by pressing the home button twice, however access speeds are not possible by the high-end devices but also improving significant improvement compared to awaken the screen and access the camera app from the lock screen fast as many other devices. Additionally, the ability to support the 4G network is also a need to mention the advantages for the operator Viettel recently tested 4G and surely will not be long now become popular, unfortunately the trial in Vung Tau Viettel up Can not check their 4G speeds on really quickly.
About configuration, equipped Samsung Exynos chip "homegrown" for its cheap device instead of chip Spreadtrum few names. Version 4's Exynos on J2 speed 1.3 GHz GPU Mali-T720 comes, this is one of the best GPU price range for many other devices are still using version Mali-400 or Mali- 450. However, only J2 RAM of 1GB - a minimum amount of RAM to be able to play all the games on Google Play so hard to fight the heavy game as smooth as is.
When gaming tests, that it really surprised when the graphics set the highest level with Asphalt 8 but then the J2 try playing this right is "not know their best quality." Machines that annoying lag, inhibition is more than Flappy Bird, when the medium is reduced slightly better, if you want smoother racing must be reduced to a low level. And of course when dropped down synonymous muoc graphic effects in the game are significantly reduced, a phenomenon also appears more porous.
As we continue to experiment with a very heavy game that NOVA 3, it suddenly appeared, shooting dramatic scenes are not interrupted by hiccups, lag. And with games like Zombie Tsunami lighter or Temple Run 2 are not too difficult to machine. About capable gaming, multitasking you can follow the video below to get an objective observations to herself, her note with Asphalt 8 corrected lows.
When scoring performance with popular applications like AnTuTu Benchmark, Geekbench 3 also not high, only own PC Mark score J2 Galaxy scored fairly. Specifically you can monitor screenshots and comparison charts with other equipment below:
Really, I was disappointed that the Exynos 4 chip point where it's a lot lower MediaTek chips fitted to other devices in the price range. Personally, the experience still lags rivals such as Lenovo A7000 or Alcatel Flash 2 pretty much, if not take the time to scan RAM, after a day use starting jerk, even suspended, if used with multiple effects hour service and only enough to make the machine and move slowly.
Not in terms of quality, but when looking at the statistics, perhaps the Video Explainer Kit inferior rather than rivals with just a 5-megapixel main camera and secondary camera of 2MP stop at this price range, while many devices equipped with 8MP camera duo / 5MP. But we can still hope that the quality of images taken with the Galaxy J2 not too bad because Samsung inherent dislike racing number "dot" for its cheap device but are at a quality equivalent to those letter.
To test you can follow some pictures taken from J2 below:
Shooting backlit also not good, unfortunately the machine without HDR
And here are two plates plate paronama shooting, I was surprised because of their processing algorithms are very good, did not occur in the extension fractures image when taking a picture though slightly shaking his hand.
One drawback of the Video Explainer Kit Review imaging software J2 is not supported to improve the quality HDR images in bright situations difference, manual mode of the machine also can adjust ISO and of course the speed Shutter ISO adjustment is limited, nor meaningful. Overall quality of Video Explainer Kit camera after inadequate, focusing speed is slow, and if in the process of shooting the machine will shake hands not in focus and of course will be out of focus. But in the segment of cheap, it is not too much to insist on the ability to take pictures except for a few exceptions.
And the front camera of J2, only stopping at acceptable, if capture enough light still pictures "Madness" enough to post on Facebook. Below is a sheet at about 5pm selfie outdoors still bright, the machine automatically remove acne, whitening face but look closely, there's a difference, "mild" compared to neck, if you want a photo " donkey sex "than they probably need a third-party application again.
This is the most impressive to me only when the machine is equipped with 2000mAh battery capacity, but for a great time to use, in many tests J2 also proved superior to some storage devices 2.200mAh pin - 2.500mAh I've ever experienced. Here's his chart record when testing 4 basic tasks, each task in one hour with a wifi connection.
Perhaps thanks to Super AMOLED screen with a resolution of modest size and also a bit smaller than many other devices so when watching movies offline (HD) in 1 hour takes only 9% pin machine so time watch Continuous movie can be up to 11 hours. And also in this condition can fully Galaxy Head J2 than 5 hours of gaming, not much equipment to do so even mid-range devices. If using alternating tasks J2 can withstand 7-8 hours of continuous operation, so one day use is not a problem. And maybe also because no more wasting battery temperature of the machine should also not high, while playing NOVA 3 at noon, the body is only slightly warmer than about 38-40 degrees, even while surfing the web or task light other without attention could not detect the device is heating up.
Overall, compared to other devices in the price range Video Explainer Kit has many strong rivals like Lenovo A7000 have outstanding performance, Alcatel Flash 2 with camera "crisis" last good configuration and many other devices, but you wanting to choose their own branded smartphone, the J2 is a brilliant candidate. Also on display plus point is also a huge advantage over their opponents, the performance is not so good but still heavy enough to fight the game, even if just surf the web, read your newspaper is under no reproach in 3 million price range.
