Fix Samsung Galaxy S6 Edge that shows “Warning: Camera failed” error after the update

When you open the Camera app on your #Samsung Galaxy S6 Edge (#S6Edge), two things run simultaneously; the app itself and the camera sensor or its hardware. If one them doesn’t work the way it should, you’ll get the error message “Warning: Camera failed” or some other things may happen like the app closes as soon as it’s opened.


Some owners started complaining after the recent Android 6.0.1 #Marshmallow update, which gives us the impression that it’s a bug or a glitch in the new firmware but we really don’t know for sure. So, we need to do some thorough troubleshooting to be able to understand why it happens or know the cause. Once we have that information, we can easily formulate a procedure to fix it or explain to a technician accurately what’s happening to your phone.

Camera failed signs

  • Error message “Warning: Camera failed” shows up as soon as the camera opens
  • Error pops up when switching from back camera to front-view or vice versa
  • Camera closes immediately after opening without giving out an error
  • Camera takes too long to focus and then closes
  • Error pops up while trying to view pictures through Gallery

Possible causes

  • The Camera app crashes due to corrupt cache and/or data
  • The camera sensor has issues affecting the app when activated
  • Some features conflicting with the normal operation of the camera
  • Both the app and the hardware have issues
  • There are too many pictures that Gallery freezes while trying to view some affecting the camera


I have my Galaxy S6 Edge update to marshmallow and shortly after the installation, I was getting the error message, Camera failed. I tried rebooting the phone a few times and the problem became sporadic. It only occurs if it wants to but I don’t like it because what if the issue occurs when I’m trying to snap an important picture? I want my new phone to be without issues, that’s all. Help me please.

Hi droid guy. Every time I open the camera app I get the message saying the camera failed and there’s no other option but to touch OK and then it closes. When I open it again, the same thing happens. This problem started after I updated my device to marshmallow. Can you help?

Step-by-step Troubleshooting

While we want to help you fix the problem, there’s no guaranteed fix here especially if the problem is hardware-related. All we can do is learn more about the problem so we’d know what to do or what to say when the technician ask us questions. But before resorting to having the phone repaired, try these troubleshooting steps:

Step 1: Immediately isolate the problem by knowing if it’s caused by third-party apps or not

Boot your device in safe mode to temporarily disable third-party apps. If one or some of the app has something to do with it, then the error message shouldn’t show up in safe mode.

  1. Press and hold the Volume Down and Power keys for 20 to 30 seconds.
  2. Once you see the Samsung logo, release the Power key immediately but continue pressing the Volume Down key.
  3. Your phone should continue booting up and you will be prompted to unlock your phone as usual.
  4. You will know if the phone successfully booted in safe mode if the text “Safe mode” is displayed at the lower-left corner of the screen.

While in safe mode, try using the camera app, viewing pictures through the gallery and take some to test it out. If the problem doesn’t occur, then issue is with your third-party apps. Find the culprit and uninstall it but if you don’t know which app, then backup your data and reset the phone.

Step 2: Disable Smart Stay if issue still occurs in safe mode

Smart Stay uses the front camera to detect or scan the owner’s face if enabled. So, if the error message still shows up in safe mode or if the camera force closes without warning, turn off Smart Stay and then test the camera again.

  1. From the home screen, swipe down the Status bar.
  2. Touch the Settings icon.
  3. Scroll to and touch Display.
  4. Touch Smart Stay to open its settings page.
  5. Touch the Smart Stay switch to turn it OFF. Don’t enable it if it’s already off.

After turning off Smart Stay, try to reboot your phone normally and then open the camera again. If the error still occurs, then it’s time you did those general firmware troubleshooting procedures.

Step 3: Clear the system cache first since the problem occurred after an update

All apps and services have their own system caches that are created when the phone first booted up or after the installation of the apps. These files may have been corrupted during the update or the old files doesn’t work with the new system. You need to clear these files so the phone will create new ones and you can do so in recovery mode.

  1. Turn off the device.
  2. Press and hold the following three buttons at the same time: Volume Up key, Home key, and Power key.
  3. When the phone vibrates, release the Power key but continue to press and hold the Volume Up key and the Home key.
  4. When the Android System Recovery screen appears, release the Volume Up and Home keys.
  5. Press the Volume Down key to highlight ‘wipe cache partition.’
  6. Press the Power key to select.
  7. When the wipe cache partition is complete, ‘Reboot system now’ is highlighted.
  8. Press the Power key to restart the device.

If wiping the cache partition didn’t work, you have no other option but to do the reset.

Step 4: Perform the master reset to give your phone a fresh start

Backup all your data, remove your Google account and disable screen locks to make sure Factory Reset Protection (FRP) isn’t tripped during the reset. You reached the point wherein you need to delete all data and settings in your phone and bring it back to factory defaults.

  1. Turn off your Samsung Galaxy S6 Edge.
  2. Press and hold the Volume Up, Home and Power keys together.
  3. When the device powers on and displays ‘Power on logo’, release all keys and the Android icon will appear on the screen.
  4. Wait until the Android Recovery Screen appears after about 30 seconds.
  5. Using the Volume Down key, highlight the option, ‘wipe data/factory reset’ and press the Power key to select it.
  6. Press the Vol Down button again until the option ‘Yes — delete all user data’ is highlighted and then press the Power key to select it.
  7. After the reset is complete, highlight ‘Reboot system now’ and hit the Power key to restart the phone.

If the reset failed, it’s time to let a technician check it up for you. It might be a more serious firmware or hardware issue. The technician may manually reinstall the firmware or further check the camera sensor.

  1. My S6 Video failed shortly after Google+ (or a Google+ update) was downloaded. After reading your info I Force Stopped the App, no joy, I disabled the app and turned off all the permissions, no joy, finally I deleted the Google+ app (which I don’t use anyway) and instantly the Video Recording works again. My phone has all of the latest updates to the OS as of 7/4/2017.
