How to troubleshoot your Galaxy S7 with “Camera failed” error

Problem: when I open the camera of my phone, instead that the camera opens, an error would pop up telling me that it failed. I can only tap OK but it doesn’t really fix the problem, just gets rid of the error. When i try to open the camera again, the same thing happens. I’m not quite sure when it happened or how so I can’t provide you with more information about this problem. But have you guys encountered this error before? And if you do, can you fix this error? Thanks in advance.

Troubleshooting: Yes, we’ve already encountered this error message several times in the past and we may know how to fix it depending on the situation. Please note that if we found out it’s an issue with the hardware, you may need a technician or you may want to bring the phone to a shop so that further tests will be conducted to determine if it’s really a hardware problem or just an issue with the firmware. With that being said, here’s what I suggest you do about it:

Step 1: Try opening the camera while your phone is in safe mode

First off, booting your phone in safe mode won’t fix the problem but it will give you a hint as to what really caused it. What we are trying to do here is to determine whether one or some of the apps you downloaded and installed from the Play Store is causing the problem. By starting your device in safe mode, you’re actually temporarily disabling all third-party elements in your phone. So, if the camera doesn’t show up the error when in that mode, then it’s clear enough that the error is triggered by, at least, one of the apps that’s installed on your phone. Then,  you just have to find that app and do something about it.

Now, here’s how you run your Galaxy S7 in safe mode…

  1. Turn the device off.
  2. Press and hold the Power key past the screen with the device name.
  3. When ‘SAMSUNG’ appears on the screen, release the Power key.
  4. Immediately after releasing the Power key, press and hold the Volume down key.
  5. Continue to hold the Volume down key until the device finishes restarting.
  6. Safe mode will display in the bottom left corner of the screen.
  7. Release the Volume down key when you see ‘Safe Mode’.

Assuming the error doesn’t show up in this mode, try to recall the apps you might have installed prior to the problem. Then, try to update it first, clear its cache and data and lastly, uninstall it if the problem remains after all that. Here’s how you do all those things…

How to find updates for your apps on Galaxy S7

  1. From any Home screen, tap the Apps icon.
  2. Tap Play Store.
  3. Tap the Menu key and then tap My Apps. To keep your apps automatically updated, tap the Menu key, tap Settings, and then tap Auto-update apps to select the check box.
  4. Choose one of the following options:
    • Tap Update [xx] to update all applications with updates available.
    • Tap an individual application and then tap Update to update a single application.

How to clear the cache and data of an app in Galaxy S7

  1. From any Home screen, tap the Apps icon.
  2. Tap Settings.
  3. Tap Applications.
  4. Tap the desired application in the default list or tap Menu icon > Show system apps to display pre-installed apps.
  5. Tap Storage.
  6. Tap Clear data and then tap OK.
  7. Tap Clear cache.

How to uninstall applications from your Galaxy S7

  1. From any Home screen, tap the Apps icon.
  2. Tap Settings.
  3. Tap Applications.
  4. Tap the desired application in the default list or tap Menu icon > Show system apps to display pre-installed apps.
  5. Tap Uninstall.
  6. Tap Uninstall again to confirm.

If, however, the error still shows up in this mode or if it continues to pop up even after you’ve done all this, then move on to the next step.

Step 2: Try to reset the Camera by clearing its cache and data

Now, it’s time to go after the app that’s being mentioned in the error–Camera. The reason why this step only comes in second is because we don’t want you to lose some files, pictures or data. In this step though, all you need to do is reset the camera app itself. Just follow the steps below to do that…

  1. From any Home screen, tap the Apps icon.
  2. Tap Settings.
  3. Tap Applications.
  4. Tap Camera.
  5. Tap Storage.
  6. Tap Clear cache.
  7. Tap Clear data and then tap OK.

After this, try to open the camera to see if the error still shows up and if so, move on to the next step.

Step 3: Run your phone in Recovery mode and wipe cache partition

The problem started after the Android Nougat update so there’s a possibility that this problem is caused by some corrupt system caches. During firmware updates, some cache may automatically become obsolete while others may become corrupt. Corrupt caches may cause performance-related issues when the system continues to use them and in this case, the best thing that you should do is delete them all so that they will be replaced. To do that, all you need to do is reboot your phone in recovery mode and then wipe the cache partition:

  1. Turn off the device.
  2. Press and hold the Volume Up key and the Home key, then press and hold the Power key.
  3. When the device logo screen displays, release only the Power key.
  4. When the Android logo displays, release all keys (‘Installing system update’ will show for about 30 – 60 seconds before showing the Android system recovery menu options).
  5. Press the Volume down key several times key to highlight ‘wipe cache partition’.
  6. Press the Power key to select.
  7. Press the Volume down key to highlight ‘yes’ and press the Power key to select.
  8. When the wipe cache partition is complete, ‘Reboot system now’ is highlighted.
  9. Press the Power key to restart the device.

The phone may take a minute or two to boot up after this procedure but once it becomes active, the first thing you should do is open the camera app to see if the error still shows up and if so, then you have no other choice but to do the next step, at least, before you actually bring the phone to a shop for a checkup.

Step 4: Backup all your files and data and then reset your Galaxy S7

This procedure albeit effective will be a hassle because you need to make a backup of your important files and data in your phone since they will be deleted during the reset. After the reset and the problem is fixed, then you will spend some time restoring your data and files back to your phone that’s this always comes last. But after doing all the steps above and your phone is still showing the camera failed error, you have no other choice.

So, take time to backup all the files and data you don’t want to lose and after the backup, try to disable the Factory Reset Protection so that you won’t be locked out of your device after the reset. Only then that you can reset your phone to bring it back to its factory default settings. Here’s how you do those things:

How to disable Factory Reset Protection on Galaxy S7

  1. From any Home screen, tap the Apps icon.
  2. Tap Settings.
  3. Tap Cloud and accounts.
  4. Tap Accounts.
  5. Tap Google.
  6. Tap your Google ID email address. If you have multiple accounts setup, you will need to repeat these steps for each account.
  7. Tap Menu.
  8. Tap Remove account.
  9. Tap REMOVE ACCOUNT.

How to reset your Samsung Galaxy S7

There are actually two basic ways to reset your phone but I prefer you reset it via Recovery Mode as it doesn’t only reset the phone but also reformats both the cache and data partitions. Here’s how you do that…

  1. Turn off the device.
  2. Press and hold the Volume Up key and the Home key, then press and hold the Power key.
  3. When the device logo screen displays, release only the Power key
  4. When the Android logo displays, release all keys (‘Installing system update’ will show for about 30 – 60 seconds before showing the Android system recovery menu options).
  5. Press the Volume down key several times key to highlight ‘wipe data / factory reset.’
  6. Press Power button to select.
  7. Press the Volume down key until ‘Yes — delete all user data’ is highlighted.
  8. Press Power button to select and start the master reset.
  9. When the master reset is complete, ‘Reboot system now’ is highlighted.
  10. Press the Power key to restart the device.

But if you want, you can also reset your phone from the Settings menu…

  1. From any Home screen, tap the Apps icon.
  2. Tap Settings.
  3. Tap Cloud and accounts.
  4. Tap Backup and restore.
  5. If desired, tap Back up my data to move the slider to ON or OFF.
  6. If desired, tap Restore to move the slider to ON or OFF.
  7. Tap the back key twice to return to the Settings menu, then tap General Management.
  8. Tap Reset.
  9. Tap Factory data reset.
  10. Tap Reset device.
  11. If you have screen lock turned on, enter your PIN or password.
  12. Tap Continue.
  13. Tap Delete all.

If, however, the problem still happens after the reset, then it might be an issue with the hardware and you need a technician to take a look at your device; bring your phone back to the store or to a shop.

Please note that if the problem occurred after got dropped on a hard pavement or got submerged in water for over 30 minutes, the technician or the store may not honor the device’s warranty and you may have to pay for the services of the technician as physical and liquid damages aren’t covered by it.
