Recently I had a momery card problem with my J7 prime samsung. Few day back I had software updation issue which was resolved only when I done factory reset and lost some of my files out of it. Now its not detecting my memory card. When checked with my friend who works in a service centre, I was informed that there may be misplacement or broken card issue. I checked it found nothing. Now I surfed internet for resolutions and foubd nothing too. So im in a mind of changing my mobile. This is really ridiculous to have changing mobile frequently due to technical issues.Guys please dont go for this mobile .its noway worth of our money.
