I have been having problems playing some video, for example, Playon app will not play on my tablet, and a couple of others have problems (like Amazon video). I am thinking that this may be due to an older version of Flash being used (10.4). The problem is that I cannot install a later version from the Play Store - I get an error saying that an existing version has a different signature than the new one I want to install. This is way out of my experience, and the older version of Flash on the tablet appears to be a system app - i.e. it cannot be uninstalled. Does anyone have an idea as to how to resolve this problem? Has anyone gotten Playon to work with the Flame tablet?
