Thanks for you reply.
I test build the UnrealMatch3 project with development build type, and the target SDK version is 23 cause 4.16 required which installed by CodeWorksforAndroid-1R6u1.
I don’t change any other setting for UnrealMatch3, and each time i open the game from S6,it is request to comfirm the permissions for accessing the photo,media and file.
