Contact Plugin Works Except With a Huawei P20 Pro

[srhan00]

Description

• I followed the Xamarin.Essentials: Contacts tutorial (https://docs.microsoft.com/en-us/xamarin/essentials/contacts?tabs=android)

• The code works and displays what I want (Listview that displays the DisplayText). Works with Samsung/Lenovo/Motorola devices but not with a Huawei P20 Pro. Every single time there are about 1000 contacts.

• On the Huawei phone, the program freezes, and visual studio debugger says

[] [ZeroHung]zrhung_send_event: watchpoint msg buffer too long, len=51652, max is 15360 [ZrHungImpl] sendAppFreezeEvent failed!

• I don't get why Hauwei thinks the contact plugin is trying to grab too much data?? I have been researching but I can't seem to find a way to tell the contact plugin to grab "less" data?

Steps to Reproduce

1. Follow the steps in the Xamarin.Essentials: Contacts tutorial (https://docs.microsoft.com/en-us/xamarin/essentials/contacts?tabs=android)
2. Run the code in debug mode using a Huawei P20 Pro
3. Program will freeze display a message like this

[] [ZeroHung]zrhung_send_event: watchpoint msg buffer too long, len=51652, max is 15360 [ZrHungImpl] sendAppFreezeEvent failed!

Expected Behavior

Should show the names (DisplayText) of all the contacts

Actual Behavior

Huawei P20 Pro freezes and debug message says

[] [ZeroHung]zrhung_send_event: watchpoint msg buffer too long, len=51652, max is 15360 [ZrHungImpl] sendAppFreezeEvent failed!

Basic Information

• IDE: Microsoft Visual Studio Community 2019 16.9.1
• Platform Target Frameworks: Android: 10.0

• Affected Devices: Only on Huawei P20 Pro

  Any ideas?

Thank you!

@srhan00 Hi I don't have a Huawei P20 Pro. And I don't think the issue is with the specific phone. You can copy all contacts from this device to another and check a behavior?
