The earlier Flash 10.3 has some flaws and compatibility issues that Adobe has tried to address with the latest update - Flash Player 10.3.186.6. It brings compatibility fixes that could resolve any unexplained issues that were being faced while viewing Flash enabled content on Android devices.
Two of the main updates to the Flash player include enhanced compatibility across domains allowing content on various Flash formats to be played on Android devices and along with that the security of the Flash player has also been juiced up.
Some device specific enhancements and compatibility notes have also been addressed with this update that bring more compatibility to playback Flash content on some Samsung, HTC and Motorola devices. Overall this update looks like a compatibility upgrade to the application.
Flash Player 10.3.186.6 is available for devices with Android 2.2 (Froyo) and above. The new update can be manually upgraded by the users or can be updated automatically through the Android marketplace. Users who do not have Flash 10.3 installed on their devices can update the same via this link too.
