First of all, you will be amazed by its display.
Samsang gives a super Amoled panel having 6.4 Inches Super Amoled .
While as , having HD Plus display is not satisfactory, It should have been with Full HD Plus display.
It works on samsang ONE UI. We see infinity V Nodge in this phone which is good.
However, its fingerprint sensor is little bit slow than redmi phones. While as, It's face lock works faster than finger print.
Coming to camera, we see Dual A Camera setup on back which is 13+ 5 MP and it's front camera is 8 MP.
What I see is , Back camera is good and front camera is average.
Having Android PIE , it gives you 3GB RAM and 30GB ROM of which 10 GB is already occupied so you get almost 20 GB Free Space. You can also use Memory cards.
It's processor is EXYNOS 7884 which is satisfied.
Also it gives you 4000MAH Battery therefore a good battert backup.
