Bug description

I've disabled my system WebView as the updated version takes huge amount of space (while older versions are not safe for security) of low end device. I assume it requires only to solve CAPTCHA? Is it possible to redirect this to users' browser & solve them from there only?

Oh boi.. You NEED at least one Webview app on your phone- it's ESSENTIAL for many (even non-Google) apps to work at all!! Why on earth would you disable it? Please THINK or at least educate yourself about any system app before doing such things

Correct, disabling it also won't save any storage...?

ESSENTIAL for many (even non-Google) apps to work at all.

1. I don't use Google apps 2. I don't prefer using WebView dependant apps as you can't change your system WebView app ; unless you're rooted, which is most likely an overlay to use another webview)

Why on earth would you disable it?

I know what I'm doing. I mentioned it clearly on the description "the updated version takes more space". So disabling old-default version saves some device space. (not because you disabled it, but due to not being auto-update to latest).

No point in discussing about user preference on enable/disable WebView.

We should focus on the main topic here i.e. why we need WebView? If it's only to solve captcha...can it be redirected to browser instead. (Solving such basic captcha is weak form of verification to detect human vs bots, but that's the upstream Signal topic)
