While checking for the behaviour on different Android tablets I found the detection of flash to be very misleading.
I get back to that later.
However it made me check on my own HTC Desire Z with Android 2.3.3 now also updated to 2.4.
I disabled flash in my default browser and to my surprise my newer KRpano sites are trying to use HTML5 with very weird results.
Sites from last year KRpano 2011-05-20 detects correct as flash.
Other browsers, Dolphin Opera and even Firefox (which does not support flash) is detecting the newer tours as flash
Also the tablets I have tested with Android 3.1 or 3,2 do it correct.in the default browser.
See the attached files. These are same tour in default browser and in Dolphin.
