Christine_ASUS1) Only after dialing or receiving a call (but not everytime).
Thank you for your asking. Kindly provide the information below so that we can better assist you.
1. Does the issue appear right after any system/apps' download or update?
2. Does the issue appear with normal mode/earphone/speaker?
3. Does the issue only appear in normal Call app or does it appears in any apps like Messenger/Whatsapp..?
4. Please try to enter "Safe Mode". If the function works well in Safe Mode yet the issue remains out of Safe Mode, please check on any disturbance from the installed 3rd party apps.
