How can I remove the word demo in bold red colour out of my android tablet

[Pretty cyndy]

Can't read anything because of demo that appears in the front screen of my tablet. The make is dualcore-A23, GA10H, Android version 4.2.2 allwinners tablet.

How did that get there? Need some details about this, it should not just show up on it's own. Things like that are usually placed there by a vendor to show that the device is a demo unit. If you bought it that way, contact whoever you got it from to get help.

While I do not have a solution, I have read about this issue on "generic" tablets while working to fix a browser homepage reset issue I was having with mine. The cause is a firmware "trojan" (for lack of a better term). When security software catches and removes the problem, a packet file is removed which triggers the DEMO screen. The site I reference below mentions the CloudService.APK, but I guess it could hide elsewhere.

see this for a bit more info.
