How to Fix Samsung Galaxy S7 Camera Failed

Samsung proudly talked about the camera when they launched the Galaxy S7. Undoubtedly, many of us bought the phones hoping to take splendid selfies and shoot great videos. But it can be frustrating when you want to capture a moment and all you are left with is a message on the screen that says “Warning: Camera failed”.  Now you don’t have the option to do anything but close the camera and try re-opening it hoping that the error solves on its own. While the warning comes all the time for a few users, other users have noticed that the error is intermittent.

Some of the possible solutions for the Samsung Galaxy S7 Camera failed issue are:


Solution 1: Restart the camera

If this is the first time you have noticed this problem coming up, then this is the first thing that you should try. Restart your camera and the warning should go.


Solution 2: Disable Smart Stay and restart the phone

If restarting the camera does not solve the problem then restart your phone to fix the issue. Sometimes restarting the phone can be helpful in fixing glitches. But before restarting the phone, disable the smart stay feature. Since smart stay also uses the camera to detect the user’s face, when you try to use the phone’s front camera, you may end up with the warning. To disable smart stay, tap on the Apps icon from the Home screen and look for “Settings” and tap on it. Now tap on “Display” and then tap on “Smart Stay”. Switch it Off by touching the toggle and then restart your phone.

  • Press the power key to select the option and use the volume key again to highlight yes and press the power button to select it
  • Once this is completed, choose “Reboot system now” and press the power button to restart your phone
