Used this device for a while and got surprised to see the things this phone offers at this price from SAMSUNG.
Camera:- One of the fields where this phone excells and beats the competition is its camera though both sensors are 13 mp with led flash on both sides this device has got an f1.7 aperture on the rear and f1.9 on the front which improves low light camera performance .
Performance:- It has got mt6757 aka helio p20 which an octacore chip with 4 A53 clocked at 1.6 ghz and other 4 A53 at 1 ghz even though this is mediatek processor this isn't that bad and can do most of the task without a hiccup and play most games fine though asphalt 8 will lag at max settings but will work great in medium settings and multitasking will be great and this will do all the task without hurting the battery as it's a power efficient processor.
Display:- This packs a 5.7 inch full hd lcd display with good viewing angles and always on display too but it could have been better if it had Super Amoled but this isn't bad.
Interface:- It comes with android 7 nougat with SAMSUNG experience skin on top which is by all mean one of my favourites and is better than its predecessor touchwiz
Battery:- It's got 3300 mah cell which can last 1.25-1.5 days without new charge and like icing on the cake the processor helps it go further than 1.5 days with ease.
Design:- All metal body only with top and bottom rear made out of plastic and great design and boost the phone's looks .
Overall:- This phone is a great deal with major sensors which were absent but now present in the new j7 model and with great cameras, good battery, impressive design, Smart Glow (alternative to led light which Samsung didn't give ), sufficient ram and storages and good price this one is direct fighter to oppo and vivo devices and I'm sure it will excel them without any failure
in the sub below 20k categories. And definitely a step in the right direction.
