I wish I could uninstall the default camera app. I like all the features made available by this app.I must report that there is inconsistency between the angle reported by the app and the visual grid 1/3.If I align the horizon [at sea] with the grid  the app reports an angle of 1.2-1.5 degrees instead of 0.Also I couldn't use Storage Framework in Android 5  no SD Card to choose in the dialog and no options to make it available.
