Unfocused of Entry Control not working properly on few Android devices

Hi,

I have two entry controls in my Xamarin forms. I have registered to Unfocused event of both entry control with respective target methods. The Xamarin forms version I am using is "3.6.0.344457". Here, when I Unfocus from first entry control and set focus of second entry control, the Unfocus event of both the entry controls i.e. first and second entry control get called.Whereas, it should only call UnFocus of first entry control. Also, when I erase whole content from second entry control using backspace key of softkeypad, UnFocus event of second entry control gets called. Whereas the Focus is still on "Second Entry Control". This happens only on certain Android phones like Huawei, Google Pixel with Android version 8.0.

It works perfectly fine on samsung S8 and S10 phones having Android version 9.0.0.

So, Can anyone guide me whether it is OS specific issue and why it is working fine with some devices.

Waiting for the answer.

Thanks in Advance,
