Black screen, application not response after used native file manager and try to show rewarded or interstitial ad. If fold down and open again - reload application or still keep in black screen. OS button "Back" not works, not close black ad.

This happens on Russian version on Redmi Note 9, on Indonesian not reproduce, but Indonesian version got this black screen if fold-unfold application.

Steps to reproduce:

1. Load rewarded ad
2. Pick file using native file manager (Android Goodies plugin, common used by Unity users)
3. Show rewarded ad
4. Black screen 70-80% times, but sometimes can work fine 3-5 ads open

Hi @Alekxss

This sounds like a device specific issue which we will have trouble solving. Have you tried talking to the creator of the file picker plugin? Perhaps there is an issue relating to returning focus to the correct activity.

Hi @NVentimiglia

No, didnt tried, as on all another devices it not happens (Oppo, Vivo, Samsung) and it looks like OS cleanup loaded ads data on application lost focus. Yes, very specific. Can you add some method to check, do loaded ADS (both rewarded and interstitial) still in memory and safe to open? As now we blind show loaded damaged ads after ads loaded callback, and crash application :(
