Samsung Galaxy J7 looks all in all a perfect smartphone in Bangladesh for the price. First comes the network capacity. It is supporting 4G network for super fast internet browsing. Although the highest network capacity in Bangladesh is 3.5G as of August 2015, you need to recall that 2 years ago we didn’t have 3G as well! So, if in near future 4G is available in Bangladesh, you can make the best out of Galaxy J7.
Then comes the battery. It has a powerful 3000 mAh battery. But the question is not only how powerful a battery is but also how big and bright the display is. As, display drains battery the most. It has a 5.5 inch super AMOLED display. Usually the bigger the display is, the more battery consumption will be and super AMOLED is a battery friendly display technology. So, all together it will be able to provide about 18 hours of talk-time which is pretty good comparing to most of the other smartphones in the market. Galaxy J7 also has ultra power saving mode which will turn off unusual apps running in the background as well as put down the display brightness to the minimum.
Camera is same and as good as Samsung Galaxy J5, which is coming at a lower price. 13 MP back and 5 MP front both allows LED flash for low light photography and the back camera has autofocus, f/1.9 aperture etc. for producing much sharper, clearer and brighter images. Gaming will be a charm with adreno 405 graphics, octa-core processor. But the only disadvantage of this phone in our opinion comes in this point. It has a 1.5 GB RAM. With 2 GB RAM gaming and multitasking could be much more relaxed. If you analyse the market, you will see brands with good reputation like Huawei, Asus, Xiaomi etc. are already offering 2 GB RAM even in a lower price. So, 2 GB RAM could definitely increase the sales of this phone as per our analysis.
Some other advantages and fine features of Galaxy J7 are dual SIM, 16 GB internal memory, Full HD video, smart manager, snapdragon 615 chipset.
