Hi Hakob,

The issue you have reported is similar to the one we have logged https://feedback.telerik.com/xamarin/1569472-entry-android-watermark-is-not-visible-with-the-latest-xamarin-forms-update-5-0-0-2478 

RadAutoCompleteView uses RadEntry internally as input control. The bug status is in development. If passing testing the fix will be provided with the next official release. 

Use the workaround suggested in the feedback item - set the Watermark property in code behind using a dispatcher:

Device.BeginInvokeOnMainThread(()=>
{
    autoCompleteView.Watermark = "write your text here";
});

Regards,
Didi
