SANSUNG GALAXY J7 is the best mobile ever I had in my used mobiles list. the j7 mobile has smart manager which allows to reduce the clean ram junk and cacthes files. font selfie led flash, it is the most attactive and excellent feature where any other mobiles have not there. the most important and the best feature is ultra data saving mode where we have this feature only in j series in samsung mobiles. the mobile is slim so that it looks very good. the mobile looking is awesome. the ram is little bit less when it compares to other mobiles but it is running very fast as compared to the other mobiles even they has more ram than the samsung galaxy j7 mobile. the samsung mobile experiences you in the gaming point of view. it supports high gaming and graphics. the best mobile under 15000.
