This is a Google Play "No connection" error.
Google Play is very sensitive to the following services and conditions:
If any of these services are not working as expected, you will receive this error.
In order to fix this error, the first step is to go into the settings of the device and enable the option "Set time automatically". This is normally under Settings > Date & Time. This should be done, followed by a power cycle of this device. This normally corrects the network time protocol (NTP) setting in the device and fixes the issue. Other testers may change this option for any number of reasons, which can cause the error listed above.
Ensure that the device has working WiFi or Cellular service. In some devices, the WiFi or Cellular services may have been disabled by another tester. Ensuring that WiFi is enabled on the device on the Perfecto WiFi network, will allow use of the Google Play store.
Ensure that you, the tester, have a valid GOOGLE account. Perfecto does not provide a GOOGLE account. Testers are responsible for creating and using their own GOOGLE account. This can be done from the device, or from GOOGLE's website. For your convenience, ere is a link to GOOGLE's account creation tool. Click on the sign up button on this page to create a GOOGLE account.
If these steps fail, please open a case with the Perfecto Support team regarding the device.
