In 2016, Samsung seems to simplify the reading of its range of smartphones. Thus, one should not find that the S and Note series for the high end, the Galaxy A mid-range and J series down the line. It is a member of the latter which is honored here, the Galaxy J7, most exclusive modest smartphones Korean. This rationalization of the range allows for now Samsung to offer much more mature terminals that a year ago, and this, in all segments.
PRESENTATION
ERGONOMICS AND DESIGN
This year, Samsung has made serious efforts in terms of design, especially in the lower ranges. Thus, the Galaxy J7 advantage of a tailored dress reminiscent of the Galaxy A5 . However, here, the plastic remains in control at the back, although it mimics the metal beautifully. The perimeter of the J7 is for its part in metal and shows little slippery.
The back has a brushed finish rather elegant and can even remove the shell to reach what has become a rare commodity: a removable battery. The back is slightly curved at the edges, a bit like what the Galaxy S7 offer.
As on all other terminals of the year, Samsung has placed the navigation keys on the strip below the screen. Only the middle button is physical, the other 2 being tactile, but we did not find fingerprint reader, yet become current device even on smartphones to less than 300 €.
The volume keys are located on the left spine, while the release button is the opposite, on the right side of the device.The first are the most difficult to reach with one hand, because you have to drag it along the device to access the index or middle finger. The Lock key is more accessible, the thumb, but could have is a little lower to further facilitate things
Whatever happens, a 5.5-inch device remains easily manoeuvrable fully with one hand, and the second will often come in the first reinforcement. The display still occupies 72.7% of the front face of the terminal; a correct scoreline to 71.5% of Umi Touch or 69.5% of Zenfone Asus Max .
INTERFACE AND NAVIGATION
Unlike the Galaxy A5 and A3 , J7 directly out Android 6.0 Marshmallow, over which the inevitable TouchWiz found. The latest version of the Samsung overlay is visually lighter than before and we do not complain to us. The whole still retains the navigation logic of the Google OS and insiders as the uninitiated will not be lost.
Beyond the look of TouchWiz that can be easily modified through the themes shop, there are a few welcome features.It is possible to switch the display on a limited part of the screen by pressing 3 times on the center button, allowing a user to easier hand. A double pressing this button opens the camera quickly, even the day before. Finally, it can automatically switch to silent mode by placing the device face down.
In addition to Google applications (Gmail, Maps, Drive or Chrome), Galaxy J7 embeds Microsoft applications (Word, Excel, PowerPoint, onedrive, OneNote and Skype). These can not be uninstalled, but do not take up any default in reality, the icon of the application leads to a download page. By default, the user sees, however gratified that 9.3 GB of free space on the 16 that make up the internal memory. The Exynos 7870 SoC and 2GB RAM accompanying do honest work. Overall, the Galaxy D7 displays a lovely fluidity, only the passage of a heavy application to another will cause a few tenths of a second slower.
MULTIMEDIA
For video playback, the surface offered by the display shows a definite asset. It is difficult to complain about not being able to view content in full HD, except perhaps when subtitles are read. all formats are still not decoded by the Samsung video player and passage through a third party application remains almost unavoidable.
The headphone output of the Galaxy J7 almost realizes a faultless. Powerful and precise, it offers a dynamic range of a good standard. Only the stereo image remains taped in the middle, where everything is higher. Overall, the performance is satisfactory. The speaker is in turn placed in the back of the device, the side of the camera module.This positioning allows him to not be completely blocked when the unit is placed on a table, optics protruding from the body of a few millimeters terminal. The audio rendering this speaker is still too limited to music listening quality, it suffices in for short videos or calls.
The display is not necessarily demanding in resources, the graphics chip Mali-T830 provides a decent job. All games on the Play Store rotate freely, the greediest generally adapting to the low resolution of the screen.
PHOTO
On the back is a module combining a sensor of 13 megapixels and an optical aperture to f / 1.9 officiating, the same as on the Galaxy A5, optical stabilization and less. The latter is not really the only difference between the two devices, the applied image processing does not seem to be the same either. While the center of the image has more or less the same level of detail, the edges degrade more quickly on the Galaxy J7. The shutter speed is waiting for you, as the accuracy of measures of exposure and white balance. The focus is accurate, but still a notch below that suggest the phases of detection devices.
In low light, things go wrong and some electronic noise appears. Under these conditions, difficult to detect details in the image. The Galaxy J7 does not really different from other devices in the same price range, who have all or most of such a report.
Video capture Full HD (1920 x 1080 px) is on his side rather honest. The display shows no ghosting during recording and the focus or exposure transitions are smooth. In contrast, low light creates the same effects as for the picture.Finally, the front 5MP sensor is what is more commonplace on competing smartphones. The level of detail is correct in full light and drops considerably when it becomes scarce. The trigger speed deserved to be a hair higher to avoidselfies blurred.
