s7 front camera error

[Lampo]

After update. Front camera is messed and my galaxy app is not opening up..it says internal error..

I suggest you to
1. update your device from setting >software update if avalable.
2. use your device in safe mode for some time if you are facing some issue

Safe Mode allows the device to boot up without  installed third party apps running, which will conserve battery power. 

 

To start the device in Safe Mode, with the device Powered Off.

① Press and hold Power key.

② Once the animation starts, Press and hold the Volume down key until the lock screen appears.

③ Keep the Volume down button until device boots up.

④ Safe Mode is indicated in the lower left hand side when enabled.

⑤ To get out of Safe Mode restart the device.

if your problem is not solve you can ask again

Troubleshooting Galaxy S7 Camera Failed Issue
The procedures I will use in this article are based on how we technicians troubleshoot this kind of problem, although there are a few steps that are based on testimonies of owners who encountered and fixed the problem.
Step 1: Disable Smart Stay feature and reboot your phone
I know it’s a compromise but it seems like this problem is connected to the Smart Stay feature that comes with Samsung’s flagship. It uses the front camera to detect the face of the user if it’s enabled and that’s where the conflict starts. Apparently, it’s an issue with the firmware so Samsung can do something about it so perhaps the next update may fix this but meanwhile, here’s what you need to do:
From the Home screen, tap the Apps icon.
Find and tap on Settings.
Tap Display.
Touch Smart Stay.
Touch the toggle switch to turn it Off.
Reboot your phone.

Step 2: Restart the camera app

Just in case the first step failed to fix the problem, you need to restart the camera app. Once the error pops up, there’s nothing you can do but touch OK and the app will close itself. Try to open it again and see if the error still pops up and if so, then proceed to the next step.

Step 3: Clear the cache and data of the Camera app
This procedure will rule out the possibility that the cause of the problem is cache- and data-related. Follow these steps:
From the Home screen, tap the Apps icon.
Find and tap on Settings.
Touch Applications and then Application manager.
Swipe to ALL tab.
Find and touch the Camera app.
Touch the Force Close button first.
Then, tap Storage.
Tap Clear cache and then Clear data, Delete.

Step 4: Try deleting the system cache
After you did all those steps and the problem remained, it’s time for some firmware-oriented troubleshooting procedures and the first thing you should try is wiping the system cache directory.
Turn off your Samsung Galaxy S7.
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 doing the Master Reset. Once completed, highlight ‘Reboot system now’ and press the Power key.
The phone will now reboot longer than usual.

Step 5: Perform the master reset
If all else fails, there’s a chance you got a defective unit and there’s nothing we can do about it, really. However, it could also be just some corrupt data or files. There’s it’s practical to perform the master reset before sending the phone in for checkup or replacement. But before you actually do that, make sure you backed up everything you don’t want to lose. If you have a microSD card mounted, transfer your files into it and remove it. Also, remove your Google account and disengage the screen lock to make sure FRP or the anti-theft feature isn’t tripped.

Turn off your Samsung Galaxy S7 Edge.
Press and then hold the Home and Volume UP keys, then press and hold the Power key.
When the Samsung Galaxy S7 Edge 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 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.

@Lampo Simply reset the camera settings to default, if this doesn't works. Please visit contact customer support and ask them Diagnose your phone via remote control. Further, you should actually visit nearest service center.
