Hey friends, I am using Samasung J7 Prime since from a last week and it is working very smoothy and really fantastic. First of all I will start from its specifications. This handset is available in 2 colors gold and black. In my opinion Black is very good its look fantastic and a royal mobile. It as a metallic body with ultra slim design and curved edges. Its has a 3 GB RAM which helps it to work very smoothly. Its ROM is 16GB, which is very less now a days. I dont like these feature because 16GB internal storage is very less and we get only around 10 GB of free storage, Samsung should improve this ROM problem. It has 1.6 Ghz Octa Core processor which enables it for fast functioning of mobile and reduce lags problem. Samsung added F1.9 lens to its camera that gives us bright photos even in low light, Ihave tried its camera and it is really very good. Its front camera is 8 Mega Pixels and rear is 13 Mega Pixels. Samsung has introduce fingerprint sensors which was not in Samsung J7-2016 model. Its fingerprint sensor is very fast and just open in 1 second which help us to secure over mobile from others. Its has 3300 mAH battery which is really a long lasting battery. I am a heavy user and battery last tills a day around 30% which is very good. Its also have Ultra Power Saving Mode which closes all background running apps to minimise battery consumptions. It has 5.5 Inch Screen. It does not has AMOLED screen which is not good in my opinion but it has IPS LCD capacitive touchscreen, 16M colors with a resolution of 1080*1920 pixels 401 ppi pixel density which show picture clearly even if we zoom it. It has Corning Gorilla Glass which do not lead to come scratch on screen. It has 6.0.1(Marshmallow) Android OS with Exynos 7870 Octa Chipset and Mali-T830MP2 GPU which gives it a very smooth and fast functioning. I Have played heavy graphic games like Modern Combalt and Asphaul 8 and did not see any lags while playing and also there is no overheating problem. I played it continuously for 30 minutes and did not face any lags or heating problem. It has Geo-tagging, touch focus, gace detection, panorama, HDR. it support microUSB v2.0 which helps to transfer fast any thing ti pendrives or copy fast anything from pendrives. Samsung has change the place of its loud speakers in J7 prime they had given it on the sides above the switch button. Its loudspeaker is really sounds very good. Its microSD is supported upto 256 GB which has different slot for memory card. Its battery is Non-Removable. The one of the best thing in this is that it support LTE which means that we can use Jio sim in this mobile. The J series of Samsung is the most selling series. As the mobile is of Samsung we get good after sell service. I would rate 4 out of 5 in looks and build design, 4 out of 5 in features, 5 out of 5 in display, 4 out of 5 in performance, 4 out of 5 in camera, 5 out of 5 in battery, It is available at RS 18790 in market.
