Does anybody has Samsung J5? They has updated the software and the upgraded Android version is 7.0 now but anybody know how to stop getting messenger/whatsapp preview messages on the top screen? I know how it worked for last version but they dont have "Hide content" option in Notifications. if anyone knows please let me know. Attached are photo of new version interface. Thanks
