Adobe gave us plenty of warning, informing us back in November of last year that it would stop supporting Flash on mobile phones. Yesterday was the last day of its support.In fact, the Flash app was also removed from Google Play yesterday, with no further updates planned for the app. Well, there are likely to be some stability updates, but only for those who already have the app loaded onto their phones. That might not sound like a big deal if you have the app in use (for example, via Gingerbread or Ice Cream Sandwich), but it might cause a problem in the coming months, as users upgrade to Jelly Bean.As Adobe states in its blog: 'If a device is upgraded from Android 4.0 to Android 4.1, the current version of Flash Player may exhibit unpredictable behavior, as it is not certified for use with Android 4.1. Future updates to Flash Player will not work. We recommend uninstalling Flash Player on devices which have been upgraded to Android 4.1.' So you have been warned.This isn't the end of Adobe on mobile devices though. As we mentioned last year, the company is focusing on Adobe Air and HTML5 applications instead. As for iPhone users, nothing really to see here. Apple avoided Flash on its smartphones, so there's nothing to avoid or uninstall.
