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?
Everyone's debating the merits of WebView but I find a browser made by CoinBase, Inc who operates a crypto platform advertising 8% APY to be way more dubious than the battle-tested Chromium browser engine.
