I can't believe how wide spread the Samsung Galaxy "camera failed to open" issue is. Its reported all over the internet. There are multiple YouTube videos about how to fix it none of which are permanent fixes. If your lucky one of the recommended methods will work temporarily, but the camera eventually fails again. Its been reported against multiple Galaxy models as well. Clearing the camer app cache doesn't work, neither does clearing the system cache partition, neither does booting in safe mode. My S10 plus camera is also having this issue. I'm very disappointed.
