We find the details in the feedback and find the Foucs MODE :0, it is the auto-focus.
Though it is not normal configurations, but it can`t influence this issue. Customer won`t complain about it strongly.
2.reconfig the settings, we find the spot in the screen is also exiting. We zoom in and find someone open the curtain.
So we doubt the spot is occurred by the sunlight。
3. we feedback this information to customer and close the curtain and this issue is solved。
