ZTE blade phone does not install adobe flash player
There appears to be really some issues between Adobe flash player and phones like yours, something about low processors on some devices. But don't worry an Adobe version specifically for those phones was made, you won't be having installation errors with this one.
I wish you could have posted the error that you are exactly getting, because if there are not compatibility issues then there might be other factors likely to cause the issue. Is your internet connection stable? Having an unstable internet connection or a connection that is too slow may be the cause of such an issue.
