Settings - Device Care - Battery - Camera
Disable "Put app to sleep"
If this setting is left in the ON position it will create conflict with app's ability to properly shut down when exiting Camera.
Hope it helps
Every time I take a picture now with my phone it says refining picture and it wont go away unless I restart the device. Every single time. What's causing this
Any screenshots you can provide?
Also are you using the stock camera app?
In any case, try this:
Tap and hold camera app shortcut on your home screen. Then when context menu appears, tap on App info. Tap force stop, then go to storage and clear data
Have you tried all the troubleshooting steps listed above?
Do you experience these symptoms if you test your camera app with your device in safe mode? If your phone is misbehaving, it's possible that a third-party app is causing the issue. To figure out what app is acting funny, you can use the Safe Mode feature. In Safe Mode, your phone won't run any third-party apps. This allows you to easily identify and remove the app that may be causing the problem.
