A fix for this issue is provided in the R1 2019 Official Release. I have tested this scenario on Android Emulator and real devices but I could not reproduce the issue. The keyboard disappears when Return/Done key is pressed. Refer to the attached video.
Could you please verify that you are using the latest version of Telerik UI for Xamarin 2019.1.116.1 and if so could you please send me a sample where the issue could be reproduced? Please note that you should open a support ticket and attach it there because in the forum only image attachments are allowed.
Looking forward to your reply.
