Both the Galaxy J7 and Galaxy J7 Prime smartphones are targeted for the mid-range market, yet both phones also feature specifications found in high-end devices. Given that they belong to the same branch and released a year apart from each other, are the changes in the Prime enough to convince a switch or is it better to stick to the J7?


“Go big” seems to be the motto of smartphone makers these days, so much so that there seems to be little difference when it’s compared to tablets. That seems to be the case here with the J7 and J7 Prime: both are around six inches long.

While both feature Home buttons in exactly the same position as other Samsung smartphones, the Prime ups it a bit by incorporating a fingerprint sensor on the button. Basically, you can just lay a finger (the device allows three choices) and you are given access to your phone.

Another big change between the two devices is the placement of the speaker: the Prime places its audio-emitting feature on the right side just above the power button. It may seem odd at first but it does have an advantage in not being muffled by fingers or other items.


Smartphones are competing with desktops and laptops when it comes to daily computing tasks. As such, bigger screens are needed and both the J7 and Prime don’t disappoint: both sport displays measuring 5.5 inches.

With an IPS LCD, the Galaxy J7 Prime performs better outdoors in direct sunlight. However, the Outdoors mode of the J7 also allows it to be useful while outside.

Processor, Graphics Card & RAM

The J7 offers two chipset variants and the one you’ll have depends on which market you got your phone from. With a J7, you get the choice of a Snapdragon 615 chipset or an Exynos 7580 processor. While both allow a smooth performance with daily tasks, the phone might still lag depending on how heavy it would be used. On the other hand, the J7 Prime is bundled with an Exynos 7870 octa-core processor with 1.6GHz power – slightly more powerful than the J7’s chipset.


Nothing seems changed in terms of internal storage capacity between the two devices: they both still offer 16GB space. However, the RAM capacity of the J7 Prime has been bumped up to 3GB compared to the 1.5GB of the J7. A similarity, however, is the ability to expand storage up to 256GB through a microSD card.


Although the J7 and Prime may be fitted with 13MP primary snappers, they differ somewhat with their front-facing cameras. The J7 has a 5MP front shooter while the Prime has an 8MP one with an f/1.9 lens which means it performs slightly better in low-light situations.


The J7 Prime is packing a bigger battery: 3,300mAh compared to J7’s 3,000mAh. While J7 users can freely remove their batteries, Prime owners are stuck with a non-removable cell. Of course, a bigger battery also means it takes a while to get the Prime charged.

The Galaxy J7 Prime looks to trump the J7 in terms of capabilities, but it still boils down to consumer preference. While some may be content with what the J7 offers, others may want the security features and improved camera and audio listening capabilities of the Prime.
