Header dissapears when clicking on the back button

I have a problem in my ionic application. When poping a page that contains an input either :

  • by clicking the OK button that sends a request to the server before poping the current page
  • or by clicking on the back button (hardware one or application one)

The headers of the pages ((that are in the stack)) dissapear.

This problem only appears when I emulate on the phone using ionic cordova run android, or when I generate the apk.
But It doesn’t show when using ionic serve --tab to run the application.

This is how I’m defining the header in the pages :

<ion-header >

  <ion-navbar >

    <button  ion-button menuToggle>
      <ion-icon name="menu"></ion-icon>

    <ion-title  color="secondary"> Home</ion-title>

    <ion-buttons end>
      <button (click)="myFunction()" ion-button icon-only>
        <ion-icon name="search"></ion-icon>



Here is my Ionic info :

   @ionic/cli-utils  : 1.9.2
    ionic (Ionic CLI) : 3.9.2

global packages:

    Cordova CLI : 7.0.1

local packages:

    @ionic/app-scripts : 3.0.0
    Cordova Platforms  : android 6.2.3
    Ionic Framework    : ionic-angular 3.7.0


    Android SDK Tools : 26.0.2
    Node              : v6.11.3
    npm               : 3.10.10
    OS                : Windows 10

Can anyone help please ?

Problem solved , it was due to the ionic version , I upgraded the ionic framework version to 3.8.0 and things are working now.
