Here is the sample i created again [https://github.com/bunday/ionic-googlemap-test]
set #mapperFacade height and width higher than 100px.
I can not say anything without code. Please share your project files on GitHub.
this is the link to the project https://github.com/bunday/ionic-googlemap-test
Thank you, you need to change <div style="height:90px" id="mapperFacade"></div> to <div style="height:100px" id="mapperFacade"></div>
And I think you don't look this slide. I recommend check out this slides before starting.

Thanks for the reply. I didn鈥檛 know the height as 100px mattered. It displays a map now, just that the map is now covering just 1/4 of the whole screen.
Did you set <meta name="viewport" content="width=device-width, initial-scale=1">?
I can't believe 100px height takes 1/4 of whole screen on any iOS devices.
I鈥檓 surprised either. Would post a picture once I鈥檓 back at work. Thanks for the swift response.
here is the image

Well, do you need Google Maps API? End user can not do anything such a small map.
If you just display a map, I recommend you use Google Static Maps API.
Which is super faster.

At least, 100px height = 1/4 of whole screen size. It seems 1/6.

Anyway, congratus for solving the original problem.
For anyone that will ever need this. the style should be 100% instead of 100px. It works fine now. Thanks @wf9a5m75
