Restore settings – Restores all settings from a beforehand saved settings file (see “Save settings”). A file dialog will seem allowing you to choose on the settings file. Be warned that choosing a file will imply all of Open Camera’s settings will be overwritten with the saved version! Also watch out for using this to switch settings between different units – there may be the danger that settings on some devices may be incompatible with other devices. Note that on Android 10+, the file dialog will solely let you select a file inside Android/data/net.sourceforge.opencamera/files/. Audio source – Select the audio supply for recording video.
