Vanadium isn't yet officially available for users outside GrapheneOS, although we plan to do that eventually.
Thank you Daniel and GOS team for best mobile chromium experience. I'll encourage everyone on android to use Vanadium by that time, even though it'll miss Vanadium webview.
P.S. It's shame that most secure browser for android now is cryptocur. bloated brave.
P.P.S. My next favorite browsers is Trivalent in Secureblue and third is ungoogled-chromium itself.
