If you see above image with “This device isn’t Play Protect Certified” notice when opening the Play Store App, please follow this guide.

  1. Press the square button on the Android navigation bar and swipe up the Play Store to close it.
  2. Reopen the Play Store app to check if the issue is resolved; if not, swipe it up again to close it and reboot the device.
  3. If the device is not rebooted after the device registration, or the google account is removed, or there are delays in the Google servers to acknowledge the certification, the device could show below warning.
  4. Click on the overlay message or manually close the Play Store app from the list of the application as explained above, reboot the device, and launch again the Play Store.

    Often just closing and relaunching the Play Store once or twice as explained above minutes solves the issues. Sometimes you have to reboot the device.

    It could happen that there is a problem with communicating with Google Servers. Check your network connection or try again later.
  5. If above steps do not solve, launch AppsProvider and Press Remove. Then repeat all the AppsProvider procedure from the beginning.
  6. If AppsProvider Remove option is not present, go to Android Settings > Apps > AppsProvider>Storage and Cache>Clear Storage. 
  7. If nothing else solves, Settings>Reset options> Erase all data (factory reset)
