For IOS and Android its fine working for me. put focus code in ionViewWillEnter().

import { Component, ViewChild, ElementRef } from '@angular/core';
 import { Keyboard } from '@ionic-native/keyboard';
@Component({
  selector: 'page-home',
  templateUrl: 'home.html'
})
export class HomePage {
 @ViewChild("Input") inputEl: ElementRef;
 constructor(public keyboard:Keyboard){}

 ionViewWillEnter() { 
    setTimeout(() => {           
      this.inputEl.nativeElement.focus();
      this.keyboard.show();    
    }, 800); //If its your first page then larger time required 
}

Input tag in html file

 <ion-input type="text" #Input></ion-input>

And add this line to your config.xml to make it work on iOS :

<preference name="KeyboardDisplayRequiresUserAction" value="false" />

I think you should make a global directive for this as you will probably want this behavior more than once.

import {  ViewChild, ElementRef, Directive, OnInit } from '@angular/core';
import { Keyboard } from 'ionic-native';

@Directive({
    selector: '[autofocus]'
})
export class FocusInput implements OnInit {
    @ViewChild('myinput') input
    private focused: boolean
    ngOnInit(){
      this.focused = true
    }
    ionViewDidLoad() {
      if (this.focused) {
        setTimeout(()=>{
          this.input.setFocus()
          this.focused = false
          Keyboard.show()
        }, 300)
      }
    }
}

Now on you ion-input field just add the autofocus attribute

<ion-input #myinput type="..." placeholder="..."
            (keyup.enter)="someAction()"
            autofocus ></ion-input>

In my case, for some reason, ionViewLoaded() was not getting triggered. Tried ionViewDidLoad() and set the timer to 200 and it worked.

150 proved too early for me. Complete Solution:

import { Component, ViewChild } from '@angular/core';//No need to import Input

export class HomePage {

  @ViewChild('inputToFocus') inputToFocus;
  constructor(public navCtrl: NavController) {}

  ionViewDidLoad()
  {
    setTimeout(() => {
      this.inputToFocus.setFocus();
    },200)
  }  
}

And on the input tag:

<ion-input type="text" #inputToFocus></ion-input>
