BUG - Sev-2 - Android - libc.so crash

[narin]

What happened?

There is an obscure bug on Android (mostly Samsung) devices that has existed for quite some time and is causing the app to crash for many users early on when launching the app.

In the past 30 days, it has affected 282 users over 300 times. Crashlytics Link

The logs do not tell us much, but some solutions either seem to suggest it is related to firebase RN packages, or an incorrect Hermes version. See this potentially related GH issue: facebook/react-native#25494.

@rarroyo23 is looking into adding symbols to the project in order to get a better stacktrace on this to help us better pinpoint the issue.

To quote @jmarchi in this Slack thread: "It looks like it’s related to the way certain android phones handle react navigations animations onto a view with a webview on it. All of the logs I went through were at the webview login and only had the login start event logged, so this tracks with the users hitting login and the app crashing. The easiest way to confirm this is to disable the animation transitioning to the login webview screen for android devices and see if we stop seeing the crash. iOS would be unaffected."

UX has given us the okay with us disabling the animation to test this theory.

On my Android devices (Nord n100, Galaxy Tab s7, Samsung Galaxy S9) going back and forth between the native app and login for webview worked just fine - animation is gone, workflow works - with the variations I used (device vs in-app navigation, initial and subsequent login, waiting for webview to fully load vs not).
