Is it possible that you can provide a sample reproduction app that I can use as a test app?

https://github.com/apache/cordova-contribute/blob/master/create-reproduction.md

This would help me focus on debugging. Thanks.

https://github.com/josephlodero/cordova-fullscreen

steps:
1: clone
2: npm install
3: cordova platform add android
4 cordova emulate android

Cordova CLI : 9.0.0 (cordova-lib@9.0.1)
Cordova Platforms : android 8.1.0

note: the video is not working due to cross origin but i think it doesnt matter. ther problem is the after the fullscreen mode and then use the platform backbutton

thank you for your help!

@josephlodero Sorry, can you create me a non ionic reproduction app? I've never used ionic before nor am I very experienced in the angular framework. Additionally having a pure cordova reproduction app will also help prove that the issue is indeed coming from Cordova and nothing that the ionic frameworks adds/overrides.

This is actually the same issue as #822

And there is a pending PR awaiting review that should fix this issue at #823

In the meantime as a workaround, you can fork the cordova-android repo, and pull in that PR to use.

To keep things organised I'm going to close this ticket. Any further discussion on this issue should be done in #822
