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.

- Open the Play Store app on the smartphone or tablet suffering this issue.
- Search for “Android System WebView”
- Select Update. If it doesn’t say “Update”, skip this step.
