Data is not committed to the Database using custom controller

I wrote a custom controller(Wizard based) and two VF pages.

My Intention is to capture the details of custom object(Candidate)Using first page I and
Using Next page I am displying the same fields and save button.

But the records are not saving and not displaying in the VF2.

Controller: 
Apex Controller:

public with sharing class CanrecordCon {

public Candidate__C Can{ get; private set; }
public CanrecordCon() {
Id id = ApexPages.currentPage().getParameters().get('id');
if(id == null) 
 new Candidate__C();
 else
Can=[SELECT Name, Phone__C FROM Candidate__C WHERE Id = :id];
}

public PageReference Next() 
{
      return Page.newCanrecord1;
 }

public PageReference save() {
try {

insert(Can);
} catch(System.DMLException e) {
ApexPages.addMessages(e);
return null;
}
// After Save, navigate to the default view page:
return (new ApexPages.StandardController(Can)).view();
}
}

Vf-page1:
<apex:page Controller="CanrecordCon" >

<apex:form >
<apex:pageBlock mode="edit">
<apex:pageMessages />
<apex:pageBlockSection >
<apex:inputField value="{!Can.name}" id="No1"/>
<apex:inputField value="{!Can.Phone__c}" id="No2"/>

</apex:pageBlockSection>
<apex:pageBlockButtons location="bottom">
<apex:commandButton value="Next" action="{!Next}"/>
</apex:pageBlockButtons>
</apex:pageBlock>
</apex:form>
  
</apex:page>

Vf page2:

<apex:page controller="CanrecordCon" tabstyle="Account">
  
  <apex:form >
<apex:pageBlock >
<apex:pageBlockSection title="Details" collapsible="false"  columns="2">
            <apex:outputField id="a1" value="{!Can.Name}"/> 
            
            <apex:outputField id="a3" value="{!Can.Phone__c}"/>          
        </apex:pageBlockSection></apex:pageBlock>
   <apex:commandButton value="Save" action="{!save}"/>
</apex:form>
</apex:page>

Please make sure you don't have constructor in the controller. The real problem here is the constructor. When you call second page, it initiate the constructor again and erase the variables. I modified the code and tested out good for me. please update the Object name <Group_1__c> to your object.

public  class CanrecordCon {

   Group_1__c Can;
    public group_1__c getCan() {

     can = new Group_1__c ();

The next method is not saving the record when you call it in your first VF page, perhaps that's part of the issue? Furthermore, in your VF pages I would add a rerender attribute to the commandButton to rerender the form and show any apex:pageMessages that come up.  For instance, your VF2 page would look like the following:
  
<apex:page controller="CanrecordCon" tabstyle="Account">
  <apex:form id="theform">
<apex:pageMessages id="msgs" />
<apex:pageBlock >
<apex:pageBlockSection title="Details" collapsible="false" columns="2">
            <apex:outputField id="a1" value="{!Can.Name}"/>
            <apex:outputField id="a3" value="{!Can.Phone__c}"/>         
        </apex:pageBlockSection></apex:pageBlock>
   <apex:commandButton value="Save" action="{!save}" rerender="theform"/>
</apex:form>
</apex:page>

Additionally, you could get by combining both of these VF pages into 1 VF page.  To do this you would render one pageBlockSection for the initial load of the page, and then a second pageBlockSection for the output portion of the page.
