The most likely cause is something on the front of the lens rather than the camera settings. A thin film of moisture, condensation, grease, or a smeared cleaning residue can scatter bright point light sources into streaks. If the smear was wiped in one direction, the flare often takes on that same directional look.

Another possible cause is moisture, mist, fog, or fine particles in the air, which can make light beams more visible, but the strong directional streaking points more toward lens contamination or condensation.

To reduce it:

• Carefully clean the lens with a clean microfiber cloth.
• Avoid wiping with a dirty cloth or just spreading a smudge around.
• If moving between cool and warm humid air, let the phone acclimate so condensation can clear.
• Check the lens before night shots, since bright lights make smears much more obvious.

If shots before and after were fine, that supports the idea that the lens briefly had moisture or a smeared film on it at the time of the bad photo.
