How can I stop the keyboard from popping up when I scroll down a document? I want the text to be uninterrupted unless I want to edit it.
This is an issue fixed in the later versions of the app. My advice is to access the Store application in your phone and updated it accordingly to reflect the latest version. Use the application's page to install the latest version of the app. The issue you've had encountered is now gone and the app is working just fine. Notice that Polaris Office might not be available in your region anymore because of certain terms and conditions.
