Well, your custom OS has not synced with the latest AOSP changes yet:

This is normal because these changes are not released yet by Google.
Therefore, for Android 16, it is barely possible to support all variants at the same time.

I suggest that you try this CI build for better chance.

[wizzwuz]

thanks, the previous ci works at least for banking apps but screenshots of videos from drm protected apps are still black, orginal module used to work well in android 15

now i have to disable liboemcrypto in order to take screenshots of drm protected apps in Android 16

If you don’t mind, may I know your device’s Widevine level? are you using a16 right?

[JingMatrix]

My device has Widevine Level L1, Android 16.
Which application are you testing against the Widevine protection?

My device has Widevine Level L1, Android 16. Which application are you testing against the Widevine protection?

He has Redmi Note Pro , running DerpFest Android 16 ROM .
TeeBroken=false

Application which don't allow to capture the screen until he fallback to L3 : https://play.google.com/store/apps/details?id=com.marrow

[JingMatrix]

Are there any other applications I can test without involving into subscriptions?

[wizzwuz]

if you like i can email you temporary login id and password for marrow app

[JingMatrix]

Marrow is not available in France.

Can you try to take screenshot of this app : https://play.google.com/store/apps/details?id=de.aok.digen

It ain't allowing me to take screenshot with DisableFlagSecure module , but works fine if I use the default toggle present on my rom :

[JingMatrix]

I will tell you the result when I can bypass the environment detection of de.aok.digen.

I will tell you the result when I can bypass the environment detection of de.aok.digen.

Only need to add it in target.txt

I'm sorry for creating confusion here , but everything works fine after going back to this build : https://github.com/JingMatrix/DisableFlagSecure/actions/runs/17380614182

You were saying the right thing : #2 (comment)

I guess we need to wait for QPR1 to use the latest DisableFlagSecure update . ( or maybe you can add some extra checks or fallback methods 🤔 )

[JingMatrix]

Only need to add it in target.txt

After this trick, I comfirm that I can take screenshot of this app.

Android 16 is evolving, I prefer to save my energy and wait for things to be stable.
