Xtreix before, 5G coverage was much less deployed than 4G coverage, 5G coverage is now expanding
Yes, that is the way of the universe... newer things replace older things. Not sure what point you're trying to make here.
All I was saying there is that if 5G did have significant security benefits over 4G/LTE, GrapheneOS would likely have made 5G-only a higher priority, rather than waiting for it to be more widely available.
Since GrapheneOS did not do that, we can infer that the project does not view 5G as a significant improvement in terms of security.
Seems to me like we are in agreement.
