Overview

Nokia 6212 Classic fails to access the device's contacts with TextField.PHONENUMBER.

Description

When displaying a TextBox using TextField.PHONENUMBER as a parameter in Series 40, the Search option can be used to open the contacts database application. However, in Nokia 6212 Classic using this option makes the device reboot.

How to reproduce

The following code snippet can be used for testing this issue:

import javax.microedition.midlet.*;
 import javax.microedition.lcdui.*;
 
 
 public class ContactTest extends MIDlet {
 
    private TextBox phoneNumber;
 
    public void startApp() 
    {
        phoneNumber = new TextBox("Tel","",12,TextField.PHONENUMBER);
 
        Display display = Display.getDisplay(this);
 
        Display.getDisplay(this).setCurrent(phoneNumber);    
    }
 
    public void pauseApp() {
    }
 
    public void destroyApp(boolean unconditional) {
    }
 }

Solution

This issue will be fixed in software version 06.20.
