To sum it up, the J7 Duo is surely not an all-rounder phone and we cannot expect it to please every kind of users. The outdated design, HD resolution, and smaller battery may not be the justifying features in the price point. However, the smartphone packs in a capable processor and impressive cameras, which is really praise-worthy. These days, due to the users’ engagement in the graphics intensive games and indulgence in the social media, they are often found seeking smartphones with a good processor and capable cameras. And we believe, J7 Duo can easily fall in the choice of such users.

Design and build
we have seen quite awe-inspiring upgrades in the J7 series over the years. The last year's J7 Max and J7 Pro smartphones had a metallic body and they felt quite premium on the hold and on the use. However, in the J7 Duo, Samsung downgraded from metallic unibody to the removable plastic back.
Display
In terms of display, the J7 Duo comes with a 5.5-inch Super AMOLED panel up front. However, the resolution is only HD. Since almost all the smartphones at the similar price are opting for a Full-HD display, the presence of merely an HD display on the device got me disheartened when I first looked into the specs. However, on the use, I did not find the lack of sharpness on the phone. With the Super AMOLED panel, the display looked vivid with darker blacks, brighter whites and with the impressive color reproduction. And I was pretty satisfied with the display on the J7 Duo during the course of the review period.
Performance
Samsung had been quite obsessed with the Exynos 7870 chipset in the past. And almost all the previous version of the J7 smartphones were provided with the same chipset. But things have changed in the J7 Duo. Samsung has provided a capable Exynos 7885 chipset in the handset, which was previously provided only in the premium mid-range smartphones like the Galaxy A8 & A8 Plus. However, the cores in the J7 Duo are under-clocked as compared to the A8 smartphones. Underclocking has made the processor power efficient without a compromise in the performance.
Software
On the software side, J7 Duo comes with Android Oreo out of the box. And to spice the user experience, Samsung has added its home-baked Experience UI on the top. The UI comes with numerous bloatware. But not to worry, most of them can be uninstalled quite easily. The pre-installed apps are not so unique in terms of feature and their presence did not seem much important to me. Some of the pre-installed apps are even redundant and seems like they are there only to challenge the Google ecosystem. So I find most of the pre-installed apps clunky and I uninstalled or disabled almost all of such apps.Camera
Samsung has always been a remarkable performer in the photography department. And the tradition continued in the J7 Duo. It is the first Samsung smartphone in Nepal with a dual camera setup at the back. The camera pair at the back comprises the 13MP and 5MP camera, both of which are gifted with a wide f/1.9 aperture. The rear camera on the J7 Duo packs in abundant details in the images with decent color accuracy. The shutter speed on the device is also really snappy so I did not find any issues regarding the shutter lags. Also, the smartphone is quite deliberate on capturing images with high dynamic ranges.Battery
The fuel the processes inside the phone, the J7 Duo is provided with a 3000mAh battery. With the HD Super AMOLED display and a power-efficient processor, I had a lot of expectation regarding the battery backup on the phone. But the battery did not back me the way I expected. With a Screen-on-Time of 4.5 hours and backup for less than a day on the normal usage, the battery falls on the average standard. It is implausible of Samsung to downgrade the battery size of 3600mAh on J7 Pro and 3300mAh on the J7 2016 to 3000mAh on the J7 Duo.
Conclusion
To sum it up, the J7 Duo is surely not an all-rounder phone and we cannot expect it to please every kind of users. The outdated design, HD resolution, and smaller battery may not be the justifying features in the price point. However, the smartphone packs in a capable processor and impressive cameras, which is really praise-worthy. These days, due to the users’ engagement in the graphics intensive games and indulgence in the social media, they are often found seeking smartphones with a good processor and capable cameras. And we believe, J7 Duo can easily fall in the choice of such users.Article Last updated: June 7, 2018
