Theres a lot to like in the Galaxy J5, the Super AMOLED display, 4G connectivity on both SIM cards, microSD card expandability up-to 128GB, a front LED flash and the much-improved Samsung TouchWiz over its previous versions. Samsung has tried to offer almost everything at the pricepoint of 12k and has managed to achieve that.
The same boring Samsung design and the limited internal memory makes the Galaxy J5 a bit unwanted in the race of affordable feature-packed smartphones.
Samsung Galaxy J5 comes across as a strong contender from the Korean giant to take on some of the best devices in sub-15k category such as the Moto G, Xiaomi Mi 4i, Asus Zenfone 2, etc. If you are looking for stock Android experience, the Moto G(2015) is the legitimate choice, while the Samsung Galaxy J5 stands out among the crowd for its sheer brand recall and years of potency.
It also comes down to personal choice whether you would like to invest in a brand that is well established in the country or opt for a newbie brand with far less market credentials.
