Flash Player is no longer supported on Android. Available options are either vulnerable to known exploits as they have not been updated with security fixes in years, or they're straight-up malware wrapped around an old Flash Player. Either version leaves your device at risk, and our recommendation is to not use them. The vast majority of malware comes from third-party app stores on Android. If you would like to keep the information on your phone private, only install applications directly available through the Google Play store.
