This error seems to be caused by any one of four culprits – a problem with Samsung’s Gallery app, a kink in the device’s cache or an application other than the Camera app that is using the camera or the device’s flash but does not completely let go of it when it is not in use, preventing the Camera app from using it and causing the “Warning: Camera failed” message to pop up. The reason why the fourth culprit behind this issue has not been described yet is because it is entirely unknown and is limited to the Samsung Galaxy S5, numerous units of which were replaced by US carriers when they were affected by this problem.

pop up. The reason why the fourth culprit behind this issue has not been described yet is because it is entirely unknown and is limited to the Samsung Galaxy S5, numerous units of which were replaced by US carriers when they were affected by this problem. While a reboot seems to be able to temporarily fix the problem for some Samsung Smartphones, the “Warning: Camera failed” error is one that needs to be fixed as soon as it shows up as a Smartphone’s camera is a huge part of its overall appeal. Well, the following are some of the methods that have successfully fixed the “Warning: Camera failed” problem for various users of Samsung devices affected by the problem:

Method 1: Recovery Mode

Method 2: Android Folder

Method 3:  Delete Alternative Camera

This should fix the issue. However, if it doesn’t feel free to post in the comment section below for further assistance.
