Bad picture after firmware update on doorbell

Any idea what might have changed after a firmware update last night? I’ve changed nothing in settings. All are HD and pics taken roughly the same time of day with similar conditions. Both day and night before pictures are clear. After firmware, both day and night look bad. Notice the lights at night are all stars after the update and during the day, it’s all washed out. Thoughts?

It looks like smudges. People have been known to press the camera lens and not the bell.

Try wiping it?


Bingo. That was it. You’ve won Human of the Day award and have permission to take the rest of the day off. Thanks
