Sorry but you've bought a device from another part of the world. It is not Samsung's issue that your have imported a device built with software relevant to a different region with different laws and requirements etc.
I am not employed by Samsung nor do I receive any remuneration as a Samsung Members Star.
Yes it is Samsungs fault. I bought this from Samsung Thailand 🇹🇭 and am entitled to the same world wide upgrade to one ui 7 Infact 7 years of upgrade exactly as Samsung state
