I recently bought an Samsung Galaxy Note 2 with Android 4.1.1
While this works quite good with the default browser and HTML5 using 1024 pixels cubefaces it has some serious problems with scaling the elements.
First I thought this was only in HTML5 but as I also installed flash on it I discovered that it does the same in flash but only in browser window.
If you go fullscreen your elements are scaled to the correct size 100% pixel size.
See the attached screenshots, Screen is 1280x720 and the popup text windo is a 440 pixel wide png.
The scaling in the left side is is 1.32
Another weird thing is that if you choose "desktop viewing " it automatically demands Flash. You can not use HTML5 in that mode.
