Hi, I have a Asus Zenfone 5 (ZE620KL) and today it happened to me 2 times, had to restart the phone. Maybe it was the last update? I don't know.

Hi friends,
Thank you for your asking. Kindly try some stay-at-home troubleshooting tips below:
1. Does the issue appear after any system/apps download or upgrade? 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"

Settings>System>Reset options>Erase all data(factory reset)
Please note that once the Factory Reset is completed, all data, apps, settings and personal information will be deleted.
