Huge spike in crashes on Android devices (2019.3.0f5)

The java stacktrace indicates, that installed app cannot find native libraries, as in it was incorrectly installed.

What was the previous Unity version you've uploaded your app with?

What was the format of file you've uploaded before and after ? (APK, App Bundle, something else?)

 

Sorry, I cannot give you my email.

In any case, if we cannot reproduce this on our end, we cannot help, even though I think the bug is on Google side.

I suspect the issue here, is upgrade process of your app, something probably went wrong. That's why installing application from scratch works fine.

So my question is, do you still have a link to your previous version of your app in Google Play Console, if so, submit a bug via bug reporter, with information how to install your older application version, and then updating to your newer version. If needed QA will request access to your Google Play Console, and provide email if needed.


As for SD card, there was indeed a bug, where if app is moved to SD card, the application will fail to launch (and will display the stacktrace you copy pasted above), but I think Google restricted such thing in higher versions of Android. Thus making it impossible to move/or install an app on SD card. Unless the devices you mention, have somehow overiden this behaviour. You can force the installation of your app to Install Storage, via Player Settings, though I am not sure if that will help you.
