So many variants or segments that Samsung launched. One that recently arrived was the Samsung Galaxy J4 2018 (SM400F / j4lte). This entry level class phone comes with a 16: 9 screen ratio, using plastic material and a removable battery.
With a Super AMOLED screen and a 5.5-inch landscape, this phone uses HD resolution (720 x 1280 pixels). Prioritizing the Android 8.0 Oreo OS, this phone has a lot of minus compared to its competitors such as fingerprint sensors and dual cameras. Here's a little review.
Bugger Design
The Galaxy J4 2018 appears slightly wider with dimensions of 151.7 x 77.2 x 8.1 mm and weighs 175 grams. Good curves on all four sides and sides of the body remind Samsung's old design. This glossy black cellphone still has a 16: 9 screen ratio with a 5.5-inch screen size, this phone is rather difficult when operated with one hand.
Front view, front camera is at the top of the screen, slightly to the right corner. While the flash LED is placed slightly to the left of the speaker hole. Under the speakers are the words 'SAMSUNG' which are quite vague and not very visible. Below the screen there are 3 buttons, the newest button, home and the back button. The home button must be pressed when used and at a glance it looks like a fingerprint sensor (apparently not).
USB port for data or charging, mic hole and audio port are placed on the bottom side. On the right side there is a power button while the volume button is on the left side. At the top of the volume button there is a hole to gouge out the rear casing so it can be removed. Turning to the back, the rear camera is placed in the upper middle position with a flash LED underneath.
When the rear casing is removed, you will see a SIM card slot and a memory card slot. This means that there are 3 slots available. To insert the SIM card, you must remove the battery by gouging it upwards. Do not insert the memory card incorrectly in the SIM card, because the position is overwritten.
Super AMOLED HD screen
One feature of Samsung compared to other products is the Super AMOLED screen. With a 5.5-inch landscape display, this cellphone that uses HD screen resolution (1280x720) looks still clear and clear during outdoor and indoor use. Although there is no automatic screen brightness available and only provides "outdoor mode" and "show control on top" screen brightness modes, but the screen does not disappoint. With 16 million colors and a density of ~ 269 ppi, this mobile screen supports multitouch 10 finger touches simultaneously. During testing the touch screen of this phone feels fast, smooth, responsive and does not experience sensitivity problems.
Android 8.0 Oreo
Using the Android 8.0 Oreo operating system, which is the latest OS, this phone has several advantages over the cellphone with the OS below. Initially it appeared that the UI included was simple because what appeared on the screen was not crowded. But after being looked inside (looking at the whole application by sliding the screen from the bottom up) it turns out that Samsung still includes its typical default features. Some additional features that look like Samsung Health (health and fitness application), Samsung Members (contains a list of feedback, support, news & tips, rewards and diagnosis), Samsung Notes (notes ala Samsung) and Samsung Max (containing saving mode, protection privacy, ultra applications and connection to the cloud).
For wallpapers, widgets and themes, there are many choices that can be easily downloaded and customized. You can even choose various icons that can be applied after you download it. The clock seen on the wallpaper when the lock screen can be customized based on the type and color of choice. Likewise, the front screen settings allow you to adjust the layout, screen grid, application grid and some other settings. Actually there are many other applications that you can use such as Samsung Cloud, Samsung Billing, Samsung Internet and Smart Tutor.
For cloning applications, this phone calls it 'dual messenger'. By default, the only available application is Facebook. So using two separate accounts for the same application is only available on Facebook. But if you install WhatsApp Messenger, then this application will appear or also appear in 'dual messenger'.
2GB of quad-core RAM
This phone uses a Quad-core Exynos7570 processor with a Cortex-A53 architecture of 1.4GHz. The performance of this phone is still supported by 2GB of RAM coupled with 32GB of internal storage space. For additional storage (microSD card) this phone supports up to 256GB. So there is no more concern for the save process to store multimedia collections. Oh yeah, for GPU, this phone uses Mali-T720. As for the power intake, this phone uses a battery with a capacity of 3,000mAh which is relatively large so you also will not be too worried if used all day with full connectivity.
To see the performance of this smartphone's innards, several benchmark applications are used. With AnTuTu Benchmark, this cellphone gets a number of 45,474. With Geekbench 4, this smartphone gets a value of 625 for single-core and 1,764 for multi-core. Using 3DMark only got 101 values for the sling shot, and also 101 for the extreme sling shot. For the Basemark OS II application a value of 673 is obtained. Testing by installing and playing online games such as Need For Speed No Limit does not get a problem and runs smoothly.
Dual SIM 4G LTE
Like most recent smartphones, the Samsung Galaxy J4 2018 is also equipped with one memory card slot and two nano SIM card slots that already support 4G LTE. You can exchange data wirelessly via Bluetooth 4.1 and direct Wi-Fi. As for location navigation, this cellphone has been inserted by GPS, Glonass, Beidou. This means that you can get more accurate navigation. Testing uses the Google Maps application, the application runs smoothly and no problems are encountered.
Multimedia
As usual, users can also use the default music player application to listen to music in various file formats. Sound output settings are available with 'dolby atmos' automatically. If you need customization, there is an equalizer with manual settings for treble bass and vocal instruments. In addition, there are also active settings for pro tube amps, concert halls and sound adaptations. Adapt sound is an arrangement by adding a personal sound profile that divides sound output based on the user's age from default, 30 years, 30-60 years and over 60 years. You can feel the sound output both on the cellphone and with the default earset which is quite satisfying.
In addition, this cellphone still provides RadioFM with the ability to record. The radioFM application looks quite simple and easy to understand. As for enjoying video shows, users do not need to install additional applications, because the default video player supports many video formats and even features trim. Experiments playing video files equivalent to bluray, the video played is not problematic.

13MP Rear Camera and 5MP Front
Unlike most phones that carry dual cameras, this phone only includes the front and rear cameras. For rear cameras with 13 megapixel resolution (4144x3106) with f1.9, auto focus and LED flash. Available photo effects consist of autumn, cream, in, forest, classic, cozy, memory, maple, blossom, breeze, fir, sunshine, gray, cookie cream, nostalgia and puzzles. As for available modes HDR (rich in color), night, panorama, pro, beauty, automatic, sticker (stamp), photo series (continuous). Beauty mode provides 3 choices for skin, face and eyes.
While the 5 megapixel front camera (2576x1932) has f2.2 and the LED flash only provides selfie mode, stickers and wide selfies. Uniquely this LED flash includes 3 brightness modes that you can set by shifting the value. The results of testing both indoor and outdoor the results did not disappoint. It's just that both the back and front cameras minus shooting macro mode or bokeh effect.

Conclusion
This entry level mobile phone feels hardware just barely. It doesn't feel what is seeded. The ability of a standard camera is also still minus the macro mode and bokeh effect. Although there were no obstacles during the testing, the performance was also not special compared to competitors in its class. The results or benchmark scores obtained are also mediocre. Maybe the more perceived value is a Super AMOLED screen, sound output both with the earset and without the earset which is better than its competitors. The rest, maybe the latest Android 8.0 Oreo OS support makes the 3000mAh battery capacity can still support full connectivity activities all day long. Of course, the big name of the brand that is carried is more value. But the choice is returned to the user.
