After trying different browsers on android I found Privacy Browser to be what I need. It have encrypted backups,Domain settings,jsless by default,Deleting all site data and Most usable UI. Only issue is It is based on webview and I am using system default webview as my device is nonrooted so how secure is to go this way?
Out of curiosity, why would you want to?
I honestly don’t know as rooting and magisk go against the principles of a secure OS that GrapheneOS strives for. At that point, it is no longer GrapheneOS but GrapheneOS-derived, and the devs will not offer support… rightfully so, in my opinion.
Is it possible? I assume it is, but probably very difficult. Has someone gone through the effort to do so? Doubtful as that goes again the target audience of GrapheneOS users.
