Question

I would like to know by what means a website may identify an Android/mobile device. I experience that some websites identify my Android 4.1 device even though I change the User Agent String of the android default browser (by typing about:debug in the address bar and changing the corresponding option in the settings menu subsequently). The sites in question contain flash. Do they possibly identify the version of the flash player?

Answer 1

There are different ways to do this. most common method is to check the userAgent. im not sure about the flashplayer version but it can identify the mobile device from the screen resolution(screen size)
