Graphical Analysis on Android requires a minimum Android OS (see chart below), and an up-to-date Android System WebView. These are updated separately, so it is possible that the WebView component on a tablet may not have been updated in years.

One symptom of a stale WebView is a white screen on launch of Graphical Analysis. If this happens, update WebView. A stale WebView file is most often found on tablets such as the Nexus 7.

  1. Open the Play Store app on the smartphone or tablet suffering this issue.
  2. Search for “Android System WebView
  3. Select Update. If it doesn’t say “Update”, skip this step.
  4. Search the Play Store for “Google Chrome”
  5. Select Update.
