We have confirmed that the calling app may not operate properly due to some compatibility issues related to phone calls.
You can improve the problem by force-stopping the calling app in settings.
How to force stop the calling app
Settings > Applications > Select the filter and sort icon > Show system apps – activate (ON) and confirm > Select the ‘Call’ app > Force stop
Additionally, we plan to release software that improves the problem, so please update your phone to the latest software when a software update pop-up appears.
That’s nice. Users need new software updates.
