Reasons of Problems

  • One of the reasons for camera failed problem could also be low battery issue.
  • Cache memory of the phone might be causing this problem.

  • Continuity issue in your phone’s tracks.
  • Any of the components might be faulty, and most of the time simply heating them resolves the problem.


  • Restart your phone and check S4 front camera.
  • Verify that your camera is not having the issue of low battery, as sometimes “Camera Failed” error message comes when your battery is lower than 30%
  • Take back up of your data and remove Cache memory if you are facing Black screen or Camera hanging problem.

    I would like to give my impression to what i found. First i realized the camera hang up problem, two weeks before I broke my S4 display. I ordered a new display. On disassebly i found my front-camera also damaged. The lense was splitted up from the ccd sensor. I took some pictures with use of a stereoscopig soldering microscope and found the bonding wires on the border of the ccd chip totally messed up and destroyed/broken. In my oppinion, there is the possibility, that already vibrations on the lense chassis can cause this problem. The chassis is flexible and glued quite near to the bonding wires, so that they can touch each other.

    If you like i can provide you the pictures. Just let me know.

    Best regards,

    • Hi!
      Thank you Dirk for this useful piece of informational. I haven’t experienced that before, so I am not sure about this, and please do send me those pictures, that will be really very nice of you and will also help me in understanding the entire thing. But in my opinion I guess the wires were destroyed / broken down when your S4 display encountered physical damage.
