Hi friends
Thank you all for your asking. I have try my ZE620KL yet didn't encounter the same issue. Please try some stay at home tip below
1. Your current firmware version
Setting >System>About Phone>Software information
If you try to update to the latest version, does the issue still remain?
2. Does it appear on the stock camera only or other camera app like Instagram as well?
We suggest that you try clearing cache & storage of Camera (long press "Camera">App Info>Storage & memory>Clear cache/Clear storage), and try to re-install camera apps and check again.
3. 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"
