Key points:
- Android 14 introduces advanced cellular security measures, becoming the first OS to do so.
- 2G support can now be disabled in managed devices to counter security vulnerabilities associated with false base stations and downgrading attacks.
- A new feature disables support for null-ciphered cellular connections, enhancing communication privacy.
- Android 12 had already introduced a modem-level 2G disabling feature for Pixel 6 and other Android devices.
- Android’s efforts to enhance cellular security encompass collaborations with internal teams, academic groups, and industry standards bodies.
I would say there is. Many providers are disabling 3G nowadays and 5G is not available for all yet, so your phone essentially uses 2G and 4G. Now, imagine disabling 2G and calling someone on a moving vehicle…
Which is why VoLTE is a thing. Well, unless you’re on a custom ROM or something and VoLTE isn’t working for you…
No major U.S. carrier gas used 2G for years. Well, at least Verizon and AT&T. Sprint did as well before merging with T-Mobile. That are shutting down 2G this year. So, not really a big deal.
Huh, that’s interesting. Then again the US networks differ from the rest of the world anyway.
Sprint sold off their 2G infrastructure before Y2K.
