Problem with UI input field in android

I have few inputfields in my game scene… when i enter text and press done/ok button of keyboard than inputfield shows blank…also in samsung galaxy S4 inputfield does not show default text also… i using unity 5. Also inputfields are not work in android 4.0 & below

Which version of Unity are you using?
I think I fixed that for 5.0.1 patch 1. Could you try a version not older that this?
