If your Camera app has started to fail and it doesn't work as intended, then you can check the instructions in this post and learn how to manually fix the issue. The Samsung Galaxy S9 Camera app is the same as it is on other Galaxy devices, so you can use the same tutorials for other models.
The Samsung Galaxy S9 devices are now running the latest Android 9 Pie firmware and we've found numerous reports saying that their Camera app has started to malfunction after the update was done installing.
Force Stop Camera App and Relaunch It:
The first thing that you need to do is to force close the application and then relaunch it to test its functionality. This method might not fix the device, but you should still try to apply it first. Go to Settings> Apps> and here you have to find the Camera app in the list. Open the Camera app options and use the "force stop" action to close it. After that you simply have to relaunch the Camera app and test it to see if it now works without problems.
Install the Latest Camera App Update:
The Camera app might not be updated to its latest version, and you should open its Samsung Apps page and update it. Go to Galaxy Store app, it should be available from your phone's app. Find the Camera app and update it to its latest possible version if a download is ready for your device.
Update the Galaxy S9 to latest Android OS firmware:
In case you have updated your Galaxy S9 to a new firmware a few weeks/ months back, and the Camera app has started to malfunction only recently, then you might want to look for new system updates. Go to Settings> Software Update menu.
If a new firmware update is ready to download you need to confirm the process and the Galaxy S9 will take care of the rest of the process automatically. If your Galaxy S9 still has problems running the Camera app, then you need to continue to the next tutorial.
Reset App Preferences:
Another action you can try in order to fix the Camera app for your Galaxy S9 would be to reset all the App Preferences. All these values are set by your phone for each application you have ever installed and launched by it since the day you bought it. The App Preferences reset can be applied in order to refresh the device and this might fix the Camera app problems:
- open Settings.
- go to Apps.
- tap the "more settings" option in the 3-dots menu.
- select "reset app preferences" option.
- confirm process.
- reboot the phone and test the Camera app.
If the issues are fixed by this method, then you are done with this post and you can close it. If the problem persists and the Camera app still crashes randomly or constantly, then you have to continue with the rest of the tutorials below.

Boot Galaxy S9 in Safe Mode and Remove Rogue Apps:
Sometimes the Galaxy S9 devices might develop some problems when installing too many apps from unknown sources, so you might want to remove these. If you wish to successfully remove apps that you think are making your some of your basic apps like Camera not work as intended, then you will have to follow the info below.
Booting into Safe Mode will only load the applications that your phone was featuring on the first day you bought it. So, in case the Camera app does work when you're in Safe Mode, then something must be wrong with the way your Galaxy S9 installed apps are running in normal mode.
You can boot the Safe Mode and use it to remove some of the apps you know you have installed lately and suspect that they might have something to do with the way the Camera app is launched. Here's how to boot the Safe Mode:
- press and hold Power until the switch off options are shown.
- next, tap and hold the "Power Off" option.
- now the "Safe Mode" option should replace the "Power off".
- tap once the "Safe Mode" option and confirm the boot.
When your device is in Safe Mode start looking for all the apps you have installed recently and think that might have something to do with the way your Camera app is opened by the Galaxy S9.
Wipe Cache Partition from Recovery Mode:
By wiping the cache partition you will remove all the settings your Galaxy S9 has stored in order to launch each app faster. Sometimes this data will get corrupted and you need to wipe it in order to force the phone to relearn the way each app works. Here's how to do it: power off the phone, then press and hold Volume Up + Bixby + Power buttons and release the buttons when the screen turns blue; wait for the Recovery Mode options to load.
From the Recovery Mode options you need to select 'wipe cache partition' and confirm the process. Reboot the phone and then you can test the Camera app functionality. If this doesn't work, then the last thing left to do would be to factory reset the phone by following the steps under the last method.
