Last year I made the mistake of replacing my Nokia dumb phone with a smartphone.
I chose a Samsung A33 because Samsung were the only Android vendor promising 5 years of (security) updates, at least in that price-range.
To add insult to injury, the workaround is to "turn off Wi-Fi calling and Voice-over-LTE (VoLTE) in their device settings" - but the VoLTE setting has been removed (with the Android 13 update?) and the Wi-Fi calling setting is somewhere else now (in the settings of the voice call app).
As far as I understand, the only workaround to disable VoLTE is to disable 4G and newer completely, by choosing "3G/2G" net mode, even for data. 🤮
Oh, and because 3G (UMTS) nets have been switched off in Germany in late 2021, I'm stuck with 2G (GSM/EDGE) now - up to 220kbit/s, that's even faster than dual-channel ISDN! 🤡
I finally got the "April Security Update" that supposedly fixes the vulnerabilities - according to news posts in late March that cited a post from the Samsung support forums or something.
Of course the changelog doesn't explicitly mention this, only vague "security improvements" - Samsungs communication on this was and is absolutely unacceptable, and so is the fact that it took about 5 months from them getting the reports from project zero to endusers like me (hopefully?!) getting fixes.
