Back button getting disappear in android device ionic2

Question

I am facing issue of back button disappearing in my ionic2 app. below are the steps after which issue is occuring

Main screen - click on icon (page 1)

2.popover will come with 3 choices (popover - page 2)

3.select any option and new page will open (here back button is visible-page 3 ) click on '+' and go to new page(page 4)

4.come back to page 3 and back button is getting disappeared.

I have not written any specific code to show / hide back button as its working properly as per the default behaviour this issue only happening on android device not on ios. how to solve this?

what is this popover you speak of is it a modal? Can you give some info about how you are navigating? — Mayank Singh Fartiyal
there is a page in my app which m opening using popover control below is code let popover = this.popoverCtrl.create('PopoverPage', { parameters }); popover.present({ ev: myEvent }); — Thakur
Did you use something like this when navigating from modal ? this.appCtrl.getRootNav().push(SecondPage); — Mayank Singh Fartiyal
No . this is what i have used. this.navCtrl.push(strPagename, { parameters }); — Thakur
this.navCtrl.getRootNav().push(strPagename,{parameters}); use it like this and check — Mayank Singh Fartiyal

import { App } from 'ionic-angular';
constructor(public navCtrl: NavController public appCtrl: App) {
  }

function(){
    this.appCtrl.getRootNav().navCtrl.push(strPagename,{params: 
     params});
}

Read about navigation with overlay components here like modals ,popover,etc.

https://ionicframework.com/docs/api/navigation/NavController/

Also getRootNav will be deprecated soon and we should use getRootNavById
