Sharing is caring!

Both the Galaxy J7 and Galaxy S7 are from the same maker: Samsung. However, the differences between both devices is as clear as night is from day. For instance, the J7 was made for the budget market while the S7 was made for consumers wanting high-end devices.

Then again, despite its budget-friendly price, the Galaxy J7 actually offers features you’d find in a high-end device. So this begs the question: should one settle for a low-end version or invest in a more expensive smartphone?


Although both feature a Home button on the lower portion of the screen, the metallic highlight is done away with in the S7. The other buttons, however, are located in the same place: the right side features the power key while they left has the volume control.


Given we constantly use our phone outdoors, it makes sense to be able to actually see the screen. Thankfully, both these phones don’t seem to have problems with outside use.

On the other hand, the S7 does have one other significant advantage over the J7: it is water resistant.


For a budget phone, the J7 actually features a bigger screen than its more costly relative: 5.5 to 5.1. However, offering just 720p resolution compared to the S7’s 1440 x 2560 resolution clearly shows why their price tags are different. Also, if you want an S7 with a 5.5-inch screen, go for the S7 Edge.

Processor, Graphics Card & RAM

When it comes to the chipset being used, both the J7 and S7 come in two variants: one with a Snapdragon processor and another with an Exynos processor. However, being the more expensive of the two, the S7 features the more advanced of the processors.

The Galaxy J7 is available in Snapdragon 615 and Exynos 7580 variants while the Galaxy S7 comes in Snapdragon 820 and Exynos 8890 offerings. Essentially, the chip you get depends on which market your phone will be sold in.


The S7 offers much more internal storage space than the J7, but the good news is that both also provide microSD card slots to increase storage capacity. While the J7 only has a 1GB variant, the S7 has 32 and 64GB variants depending on which country it’s being sold in.



This is where things get rather strange: the J7 features a 13MP shooter compared to the 12MP snapper of the S7. However, with a f/1.7 lens, the S7 is actually able to take much more clearer photos and can actually perform better in low-light situations. The front-facing cameras of both devices also deliver 5MP each but again, the sensor size of the S7 makes it a much better companion when shooting in the dark.


Both devices come with a 3,000 mAh cell with the difference being the non-removable variety that ships with the S7. That’s quite a bummer for any smartphone user. However, the S7 makes it up with its Quick Charge technology allowing a 60% increase in juice in just 30 minutes.

The Galaxy J7 and the Galaxy S7 may come from the same family but the differences between them are clear. Those who want a better version may want to check out the J7 Prime – which has better features – released this year.
