Periodically updates will appear for both the App and the KH Manager itself, this could be for multiple reasons such as adding new features or fixing bugs that have been caused by new versions of IOS and Android operating systems. It is recommended to check the App Store or Google Play store for updates on the Kamoer Remote app, also go into the settings page on the KH Manager on a regular basis to see if any firmware updates are showing, if available these will be highlighted in red. If an update is found it is always best to check both the App and KH Manager as new features may rely on both being updated for them to function properly.
