Setting TouchScreenKeyboard Capitalization

I have a problem with the native android keyboard, that it capitalizes my input. I am using it to login, so I would like it to function as a straight up keyboard. The settings for native keyboards are rather limited and can not do it, as far as I can see.

I addressed the problem on IOS a while back:
http://forum.unity3d.com/threads/setting-touchscreenkeyboard-capitalization.239745/

Here I wrote a postprocess function that did a change in the IOS project's code.

Can I do something similar on android, and if so how would I proceed. I guess I need to do Google Android project ot the like.

Kind regards
