BluePhaze Thanks for suggestion. But, it didn't work
@Ashley Thanks a lot! The orientation detection is for requirement for FGL HTML5 program. Before, they require the game to stay portrait or stay landscape. When the game is on wrong orientation, stop the game and put out message to player.
About the orientation detector, I use browser condition:
+is on mobile device
"on landscape" -> show message.
It works well on iOS and Android, but it never triggered on Kindle Fire.
Fortunately, they remove that requirement so the game is OK as long as it keep the aspect ratio using letterbox scale
@jayderu Thanks! Are you referring to Browser.Product? Worth try.
@tumira Yeah, I also just aware of that. Good news.
