I took a photo and as it was processing via HDR I backed out of the camera app. The camera notification popped up to indicate it was processing but never completed. However the photo processing is complete. Now I have a persistent camera notification that allows me to take no action and I cannot dismiss. The only way to get rid of it is to restart my phone. That's fine... I can restart... But this happens at least once a week and it's annoying as hell. Any way to prevent or fix this?
