Hi
Dawanlang Thank you for your asking. Kindly try some stay-at-home troubleshooting tips below:
1. Please try reset Network: Settings>System>Reset options>Reset Wi-Fi, mobile & Bluetooth
2. 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.
# How to enter and exit "Safe Mode"
https://www.asus.com/support/FAQ/1005163/3. Your current firmware version
Settings>System>About Phone>Software information
If you try to update to the latest version, does the issue still persist?
4. Does the issue appear after any system/apps' download or update?
