Xamarin.Forms Entry strange behaviour

Hello,
I have a page which I defined in XAML. It has 4 entries, one under another in vertical StackLayout.
First, third and fourth entries behave normally - user can enter any text inside, as expected. But the second entry doesn't allow to enter meaningless text, underlines the text entered with red line, and displays spell checker suggestions menu...
I can't see any differences between the definitions of these entries.
I'm checking the page on Android, so this Entry was represented natively with EditText.
Therefore I could probably solve this by assigning to this EditText attribute
android:inputType="textNoSuggestions", but I don't know how to set this in Xamarin.Forms.
Yesterday I installed 1.2.2 version of xamarin, so I think it may be connected - this worked fine previously.
Any suggestion?
Thanks in advance.
