Android build text is all in caps


I have an application with ionic which is working nice on the browser.
When building and running on my android device I see that all the text inside buttons is in capital letters hance:
<button (click)="doSomething()"> button text</button>
This button will look like: BUTTON TEXT on the android device, and button text on browser.

I found this issue on stackoverflow but i have no idea how to make this work with ionic…
