How to fix Samsung Galaxy S7 that shows “Unfortunately, Camera has stopped” error after Android 7 Nougat update [Troubleshooting Guide]

Understand what the error "Unfortunately, Camera has stopped" means, why your #Samsung Galaxy S7 (#GalaxyS7) is showing it up and what you should do to get rid of it.

Read on to know more about "Warning: Camera failed" error that reportedly started after the Android 7 Nougat update and learn how to troubleshoot your device.

The error message "Unfortunately, Camera has stopped" is basically notifying the owner that the default camera app crashed for some reason and won't be able to continue to run. It doesn't necessarily mean that the camera sensor is damaged just like many of our readers are afraid of. But then again, that's a possibility. The point is we won't know for sure what the problem is if we didn't try to troubleshoot the device.

In this post, I will tackle this error was well as the "Warning: Camera failed" that may occur from time to time. While we've already published a few articles about these errors, we are obliged to address it again because this time it's Android 7 Nougat that may have caused or triggered them.

How to troubleshoot Galaxy S7 showing "Unfortunately, Camera has stopped" error

The camera app, firmware and the hardware must be synchronized so that you can use the camera of your phone without being greeted by errors like this. As I said earlier, this one's telling you about the application that stopped working for some reason but since we are dealing with a phone that has recently been updated to Android 7 Nougat, we might be looking at a possible firmware issue. However, we need to verify if it really is a firmware problem or just an issue with the app. This is what I suggest you do:

Step 1: Reboot your Galaxy S7 if it's the first time the error occurred

If the problem just popped up without apparent reason or when you tried opening the app, then don't do anything just yet. Instead, try to reboot your phone a couple of times to make sure it's not just a temporary glitch with the firmware or the hardware. If the error still popped after the reboot, then move on to the next step.

Step 2: Clear the cache and data of the Camera app to reset it

The rule of thumb is to troubleshoot the app that's explicitly mentioned in an error message. You cannot uninstall it since it's the default camera app so the best thing you can do is clear its cache and data, which will reset it to factory defaults.

From Home screen, tap App icon.

Tap Settings.

Tap Applications and Application manager.

Swipe to ALL tab.

Find and tap Camera.

Touch the Force Close button first.

Tap storage.

Tap Clear cache and Clear data, Delete.

You may reboot your phone one more time and open the camera app after doing the procedure and if the error still greets you, then try to isolate the problem.

Step 3: Isolate the problem by booting your phone in Safe Mode

Booting up in safe mode will temporarily disable all third-party apps and services so you can easily isolate the problem if it's with your downloaded apps or pre-installed ones. If you can use the camera without crashing while in this state, your third-party apps have something to do with the issue. You just need to find the culprit and then disable or uninstall it. On the other hand, if the problem still continues even in safe mode, then we might be facing a firmware related issue. Here's how you boot your device in safe mode:

Press and hold the Power key.

When Samsung Galaxy S7 logo appears, release the Power key and immediately hold the volume down key.

Continue holding the Volume Down key until it finishes its rebooting.

When "Safe mode" appears on the screen immediately release the Volume Down key.

By the way, if finding the apps is an arduous task for you since it's not really easy to pinpoint which app is causing the problem, I suggest you just backup your data and files and then do the factory reset. This should take care of the problem.

From the Home screen, tap the Apps icon.

Find and tap Settings and then touch Backup and reset.

Tap Factory data reset and touch Reset device.

If you have screen lock feature turned on, enter your password or PIN.

Touch Continue.

Tap Delete all to confirm your action.

Step 4: Delete the system cache to see if the problem was caused by corrupt caches

The system cache can easily get corrupted or when the firmware is new, the old caches may have already became obsolete and when the new system continues to use them, conflicts may occur and may result to this kind of problem. Therefore, it recommended you boot your phone up into the Recovery Mode and then wipe the cache partition:

Turn off the phone.

Press and then hold the Home and Volume UP keys, then press and hold the Power key.

When the Samsung Galaxy S7 shows on the screen, release the Power key but continue holding the Home and Volume Up keys.

When the Android logo shows, you may release both keys and leave the phone be for about 30 to 60 seconds.

Using the Volume Down key, navigate through the options and highlight 'wipe cache partition.'

Once highlighted, you may press the Power key to select it.

Now highlight the option 'Yes' using the Volume Down key and press the Power button to select it.

Wait until your phone is finished wiping the cache partition. Once completed, highlight 'Reboot system now' and press the Power key.

The phone will now reboot longer than usual.

Step 5: It's time you backed up your data, files, pictures, etc. and reset your phone

If all else fails, you just have to do a general troubleshooting procedure since, at this point in time, we don't know for sure what's causing the problem and why the Camera keeps crashing, although we already have a hunch that the firmware itself is problematic, otherwise, Samsung shouldn't have halted the roll out. But anyways, it's imperative you reset your device and see what happens:

Turn off your Samsung Galaxy S7.

Press and then hold the Home and Volume UP keys, then press and hold the Power key. NOTE: It doesn't matter how long you press and hold the Home and Volume Up keys, it won't affect the phone but by the time you press and hold the Power key, that's when the phone starts to respond.

When the Samsung Galaxy S7 shows on the screen, release the Power key but continue holding the Home and Volume Up keys.

When the Android logo shows, you may release both keys and leave the phone be for about 30 to 60 seconds. NOTE: The "Installing system update" message may show on the screen for several seconds before displaying the Android system recovery menu. This is just the first phase of the entire process.

Using the Volume Down key, navigate through the options and highlight 'wipe data / factory reset.'

Once highlighted, you may press the Power key to select it.

Now highlight the option 'Yes — delete all user data' using the Volume Down key and press the Power button to select it.

Wait until your phone is finished doing the Master Reset. Once completed, highlight 'Reboot system now' and press the Power key.

The phone will now reboot longer than usual.

I hope this helps.

How to troubleshoot Galaxy S7 that shows "Warning: Camera failed" error

Unlike the first error, this one's seems to be talking about the camera sensor itself. This happens when the sensor fails to initialize together with the app and the firmware. You have to note that the firmware, app and the hardware must be in-sync so that this kind of error won't occur. But since it's already bugging you, here's what you should do:

Reboot your phone first – when troubleshooting app, firmware or hardware issues, always begin your troubleshooting with a reboot.

Clear the cache and data of the camera app – we are dealing with a camera problem and while we want to troubleshoot the hardware, we can't. So we just have to rule out the possibility that it's just a minor app problem by resetting the app itself. Just follow the steps above.

Reset your phone – this will give you an idea whether the problem is caused by the new firmware or not, although we really can't be certain about it. After the reset and the problem still occurs, then the firmware might be corrupt or the sensor itself has a problem.

Send the phone in for checkup and repair – this is your last resort and you need to do this if you still want your phone to work. The tech may reflash the firmware and if that won't resolve the issue, there will be tests to find out what the real problem is.
