The main camera is a 13MP unit - a pretty standard choice for the midrange - but the f/1.9 aperture elevates it above average and will make a difference at low-light scenes. The J7 is well-equipped for low-light selfies too, with a dedicated LED flash to help the 5MP front-facer.
The Galaxy J7 is a dual-SIM phone, Samsung didn’t bother with a single-SIM version. No huge loss if you ask us, unlike the A-series this one has separate slots for two SIMs and a microSD. Fast LTE data can be used on either card, making the J7 practical for travel or getting the most out of two data plans.
