I had bought my j7 on 21th feb 2016 and since then am suffering.seems like hv committed grave mistake buying it.within 1 month of buying it the screen is damaged with out no apparant reason.when I visited samsung care they pointed out tempered glass might be the reason and replaced the screen within 20 days free of cost as it was alredy in warranty period.after that I appiled a flip cover for protection.but again today the screen prb started to appear.when I gently press the earpiece contore area the screen goes off or some horizontal line appears.so I recommend not to everyone never ever buy this phone.samsung is making money out of cheap products fooling us.
