Menu Search No security updates by Samsung! About the undisputed qualities of this Again and again, the question of the compatibility of the "devices intended for the EU market" (Samsung's designation for the EU version) with Swiss mobile networks comes up. I wanted to know more precisely and turned to Samsung Switzerland and additionally to Samsung Germany (protocols available) with specific questions. The good news first: 5G, VoLTEand VoWLAN also work on the EU model in Switzerland, provided the provider offers the service. The very bad news: EU models with Swiss SIMs operated in Swiss mobile networks do not receive any security and OS updates! Unfortunately, it is not possible to have the Swiss firmware retrofitted by a Samsung service centre. If one compares the price development of the device on the German and Swiss markets, one suspects that the oh-so-unique Swiss firmware primarily serves to make parallel imports unattractive and to protect the Swiss maximum price. However, I would have expected such protectionist measures from Samsung last.
