I'm getting the error message below in Salesforce1, but I can't find any reference to it on google or in Salesforce's documentation. What can it mean?
The error happens when the user clicks on a detail page button which is implemented with a (mobile-enabled) Visualforce page. That VF page has a custom controller which sends an email and then returns the user to the Case that they pressed the button from.
It works fine on a desktop/browser, and it works fine for me on Samsung S4. My customer says it works on his tablet, but not on his S4 (which is where this screenshot is from).
Ideas?
Code for the VF page:
<apex:page standardController="Case" extensions="CaseSendFirstResponseExtension" action="{!doSend}" title="Case Send First Response">
<apex:sectionHeader title="Sending First Response..." />
<apex:pageMessages />
<apex:form >
<apex:commandButton value="Back" action="/{!Case.id}"/>
</apex:form>
</apex:page>
