Newbies always must ask questions. However, I really tried to do the searches first.
I use the NOAA Weather site which includes radar with animation. This works fine on my Kindle Fire but when installed on the Galaxy S4 and "Loop" is tapped, the radar screen blanks out and shows a message that "a plug in is required". I saw this one other time on another app but don't remember which one. Maybe Flash is required but I never installed anything like Flash on the Kindle. I see there is a way to download Adobe Flash but not sure that is a fully supported option.
I have found nice radar alternatives that do work via the Google App library so this is not a burning question. I'm just curious why the Kindle Fire is OK and the Samsung GS4 isn't.
