FLAG_SECURE doesn't work on some devices

[ShamanisTe]

I working on Cordova Application on Android.

The FLAG_SECURE don't allow user to take screenshot and when the application is in background, he have to see a white screen to protect information in the last view.

My problem is when I add cordova-crosswalk-engine in my project, the FLAG_SECURE working only on some devices...

I try with :

• https://github.com/devgeeks/PrivacyScreenPlugin
• add "getWindow().addFlags(WindowManager.LayoutParams.FLAG_SECURE);" before "loadUrl(..)" in my MainActivity.java

List devices tested with success :
Samsung Galaxy S5
Nexus 6 - 6.0.1
Motorola Moto 4G - 5.0.2

List devices tested with error :
Samsung Galaxy Note 2 - 4.1.2
Sony Xperia Z5 - 6.0.1
Samsung Galaxy Ace 4 - 4.4.4
