I wrote and verified my pure HTML5 web app for Tizen.

I ported it to Android and all works fine under my FLY IQ4410 device, but: 

• meta viewport does not work  properly (and I cannot pass verification in Samsung Apps Seller Office)
• audio tag does not work at all
• Media Player very buggy but SoundPool seems work fine 
• back button event cannot be handled in JS
• my app does not run on many devices just crash upon startup

 Goodbye Android!
