But if ever you might have had received this message while checking software update that says something like “The operating system on your device has been modified in an unauthorized way. Try downloading software updates using Smart Switch on your computer or visit a customer service center.”  This is a warning message that only appears for those devices that have been rooted and installed with modified and unofficial firmware.  So to be able to get the Software OTA update again, you must Unroot the Galaxy S6  first and removed any modification that has been installed on it.
