Speaking to Optus customer support it sounded like they were asking people of Samsung devices to update their operating system to Android 15.
They customer support agent was really surprised that Fairphone 5ās were being blocked. He looked up the brand and saw that itās a modern 5G phone and gets software updates till 2031.
He suggested to contact Fairphone to for a software update with the right settings for the them. So it sounds like a small setting change. Hopefully Fairphone can come back soon with a resolution. Iāll keep the forum posted.
Btw, looks like this forum has been a useful knowledge base for other Fairphone users, with Sweden being in the same situation.
