The word "Demo" is visible in the center of the screen in a big red font at all times. It is there even when you play games or go to Play Store. The tablet is not a floor model nor in demo mode.

    Could you get the screenshot and put the link here? Also, please mention your tablet model and Android version. – Andrew T. Dec 27 '14 at 14:59

    After further research (1, 2), some managed to solve this by upgrading the firmware/installing stock/custom ROM. However, we need more info to solve this specific issue. – Andrew T. Dec 27 '14 at 15:07

    One thing that I can see from the screenshot is the build number: polaris_eng 4.2.2 JDQ39 20140513 test-keys, so I'm assuming that it's using ROM for testing purpose. Unfortunately, there is not so much hint from all of these info, I couldn't find what brand it is for model C703, and whether if there is existing custom ROM. I'll try to research more, but don't count on me on this one. – Andrew T. Dec 28 '14 at 7:38

Precaution: Trojan reported in this file by MalwareBytes Mobile (from comment). Use at your own risk.


From YouTube video posted on Jose's comment,

  1. Turn on the device.
  2. Connect to your PC by the USB.
  3. Download SystemPack.apk (original: MEGA, mirror: MediaFire).
  4. Copy the .apk file to a directory on your device's memory.
  5. On your device, look for the .apk file using the files manager and install it by touching on it and following the given instructions.
  6. Shutdown your device, wait for 30 seconds, and the "DEMO" text will be gone.

Notice that the .apk file is like a "patch", so if you reset your phone into factory settings, the "DEMO" text will appear again.

Disclosure: The MediaFire mirror was uploaded by original poster of the answer. The file was uploaded as-is, without any compromise.

  • If there is a better/safer place to upload Android-related file (which is, APK file), just add/update the link. – Andrew T. Dec 31 '14 at 19:47
