                    nativeControl.SetTextSize(Android.Util.ComplexUnitType.Dip, (float)Element.FontSize);
                }
            }
            catch(Exception ex)
            {
                GlobalVar.ConsoleError(ex, nameof(CustomEntryRenderer), "OnElementChanged");
            }

        }

    }
}

I've stopped all background APIs running but still getting the same issue. We are not doing anything else after clicking on entry field also, as per other suggestions in SO,applied below but nothing worked.

Control.ImeOptions = Android.Views.InputMethods.ImeAction.Done;
Control.ImportantForAutofill = ImportantForAutofill.No;

That is to decide if CustomEntry should have an image and if HasImage=true, then on which side through "ImageAlignment" Left or Right as in enum — bhavya joshi, Jun 13 '20 at 06:40
Try to run it in debug mode and create an exception catchpoint. Then try to see if an exception is caught when you tap on the CustomEntry field — Saamer, Jun 13 '20 at 08:38
@saamer - yes, i've been running this in debug mode. No exception is thrown in any of device available to me. — bhavya joshi, Jun 14 '20 at 09:08
