I've found that within my app and within the Tiggzi tester app, that the videos won't play properly unless you select the full screen option. I'm testing my app on my Samsung Galaxy S3 running Android 4.1.1.
The audio begins playing when you select the play button, but you don't see any video unless you select the full screen option. Then you see the video and hear the audio properly.
Is there something I can do to ensure the videos play properly on Android 4.1.1 (Jelly Bean)?
