Like any other apps, the Camera app may also succumb into random errors and would fail to work as intended. If this is the first time you’re having trouble with your Galaxy A6 2018 camera app, then it’s probably just a random glitch that’s easily remedied by restarting the app and the phone itself. Here’s what you should do then:

  1. Tap to open the Apps menu screen.
  2. Tap Settings.
  3. Go to Application Manager.
  4. Swipe left to select All tab.
  5. Scroll down and tap on Camera.
  6. Tap the Force Stop button to quit the camera app.

After closing the camera app, reboot/soft reset your phone to clear and refresh it’s internal memory and dumps any errant cache files that might have also caused conflict to the camera application.

To soft reset your Galaxy A6 2018, simply press and hold the Volume Down button and Power button simultaneously for about 10 to 20 seconds and then release both buttons when the phone power cycles.

After it reboots, launch the Camera app again and see if the camera failed warning is gone. Continue to troubleshoot if the error reoccurs.

Second solution: Clear app cache and data on your Galaxy A6 2018.

Errant cache files can also trigger errors when using an application. To make sure this isn’t what’s causing the camera app to fail or to encounter an error, clearing cache and data on the camera app can help. Here’s how it’s done:

  2. Tap Settings.
  3. Go to Application Manager.

  5. Scroll down and tap on Camera.
  6. Tap the Clear Cache button to wipe cache from the camera app.
  7. You can also tap the Clear Data button to erase temporary data on the camera app.

Aside from the Camera app, clearing cache and data from the Gallery app can also help. The Camera and Gallery apps are interrelated applications and work side by side. Thus, if there’s a problem with the Gallery like when the app has crashed or become corrupted, the Camera app may also be affected. To ensure that this isn’t happening, clear cache and data on the Gallery app as well.

  1. Swipe up from the bottom of the Home screen to launch view and access the Apps screen.
  2. Tap Settings.
  3. Scroll to and tap Software Update.
  4. Select the option to Download updates manually.

Wait for the phone to search for system updates. You will then see an update notification if a new system update is available for download. Otherwise, you’ll be prompted with a message saying that your phone is up to date. Your phone must have a strong and stable Wi-Fi internet connection, ample of storage, and at least 50 percent battery to complete the update download and installation.

Fourth solution: Wipe cache partition on your Galaxy A6 2018.

If your phone’s camera app started to glitch after installing an update, then it’s likely a post-update issue that can easily be remedied by wiping cache partition on the phone. Apps and the phone system can become rogue following a system transition as some changes weren’t properly applied. To clear this out, wiping cache partition is recommended. Here’s how it’s done:

  1. Turn off the phone completely.
  2. Press and hold the Volume Up and Power buttons simultaneously for a few seconds and then release both buttons when the Samsung logo appears.

Wiping your phone and restoring the default settings are usually among the last options to consider if all else failed to offer solution. Your device may be going through some fatal system errors that eventually afflicted the camera and relevant applications on the phone. All these can potentially be rectified by a master reset. This will erase everything from your device, thus backing up critical data is recommended beforehand. Here’s how a master reset or factory data reset is done:

  1. Tap to open the Settings app.
  2. Navigate to Cloud and accounts.
  3. Tap the option to Backup and restore then turn on Back up my data and Restore options, if necessary.
  4. Go back to Settings-> General management menu.
