Recently I saw this model of samsung.On the front of the phone are the navigation keys(a hard home button and two capacitive non-backlit back and recent apps), the earpiece, proximity and front-facing camera sensors, and the Samsung logo. Volume buttons are on the left, the power button is on the right, the primary microphone and microUSB port are at the bottom, and a 3.5 mm headphone jack is present at the top. Around the back we see the 5-megapixel primary camera in the center, with an LED flash and loudspeaker grille on each side. Near the bottom is the 4G DUOS logo; the J2 supports 4G only on one SIM, with the second SIM slot only supporting 2G networks.The Galaxy J2 features a 4.7-inch Super AMOLED display, with a resolution of 540×960 pixels(qHD). Phones priced so low don’t usually offer a great viewing experience, but the Galaxy J2 defies that convention thanks to its Super AMOLED display. OLED displays are intrinsically more attractive than LCD displays, and as a result the Galaxy J2 doesn’t disappoint. The screen has a lot of contrast, gets really bright(especially when you enable the Outdoor mode), and shows very deep blacks.The Galaxy J2 comes with a 5-megapixel autofocus camera at the back, and a 2-megapixel camera at the front. The rear camera’s performance is at par with cameras found on devices in the sub-$150 price range, which is to say it’s not very good. Images aren’t very sharp, with dull colors and noticeable noise indoors.The Galaxy J2 comes with a 2, 000 mAh battery, which is slightly larger than the 1, 850 mAh battery found on the Galaxy J1. The hardware might not be too demanding - 2, 000 mAh batteries aren’t exactly large enough for everything a smartphone is subjected to today, but battery life on the J2 isn’t bad.The Galaxy J2 runs Android 5.1.1 Lollipop, with the newest version of Samsung’s TouchWiz UX on top(the one that debuted on the Galaxy S6 and S6 edge earlier this year.) If you’ve used a Samsung smartphone before, you will feel right at home when you pick up the J2.Overall its not a bad at All.
