I continue to have to hunt around for a flash player on my devices when I want such. Did you try a Chrome browser?
I tried checking flash related stuff such as flash games, flash videos, streams and nothing seems to work. Realized I had to download the apk and went to adobe's website and downloaded and installed the Flash player but even then, it still doesn't work. =/ Or am I doing something wrong? I got the S4 because it's the best Android Phone and Flash was the reason why I stuck with Android and didn't go for iOS.
