Why do lines, dots, or lights appear in my photos when using the camera app?
Flaws such as blotches, spots, and dots can appear on your photos for a number of different reasons. Screen flickering, black lines showing up, or vibration occurring that may appear in certain conditions. However, these issues that may occur with your camera are not malfunctions. Please find out more information about such phenomena below.
The most common reasons are light phenomena or dirt on the lens.
- Check your camera lens for scratches or dirt, and wipe it with a clean, damp cloth.
- If you suspect that the issue may be a hardware problem, you can run a diagnostic test.
- Be sure to check if your device's software and related apps are updated with the latest version. Please check how to update your mobile device's software.
- If the problem occurs only occasionally, or under certain conditions, it might relate to lighting phenomena.
Photography and light phenomena
Check the below common light phenomena.
Photography and light phenomena
The fluorescent lamp flashes 60 times a second depending on the AC power frequency (60 Hz).
When taking a picture or video with the camera under a fluorescent light source, a momentary flickering of light that the naked eye cannot feel may be captured, causing the image to flicker or a flicker phenomenon in which black lines appear in the picture.
This is a phenomenon according to the characteristics of the lighting, and generally does not appear in 3-wavelength fluorescent lamps, incandescent lamps, and LED lighting.
If excessive heat or high-density energy, direct sunlight is concentrated in certain areas of the camera lens, it may cause damage to the microlens on the camera. Be careful not to expose the camera lens to a strong light source, such as direct sunlight. If the camera lens is exposed to a strong light source, such as direct sunlight, the camera image sensor may be damaged. A damaged image sensor is irreparable and will cause dots or spots in pictures.
The phenomenon that appears on the camera is not faulty.
It’s a normal flare phenomenon that occurs when shooting under backlight with the sun or light located close to the screen frame or when there are fingerprint/foreign matter on the lens. It is particularly obvious when taking shoot of objects around bright lights.
To minimize the phenomenon, ensure that the sun is not too close to the screen and remove all foreign materials on the lens before taking a photo shoot. To clean the lens, wipe with a clean and soft cloth in a circular motion.
White spots on photos can be caused by light reflecting off a strong light source. It commonly appears when taking images around bright lights. To reduce light reflections, check the lighting when taking your photos.
This is a Black Sun phenomenon that occurs when part of the photo is overexposed to light. It most commonly happens when taking a picture directly aimed at an extremely bright light source such as the Sun.
This is a normal operation that can happen on all cameras with CMOS sensors. We recommend to change a lower exposure value (*Exposure determines how much light the camera’s sensor receives)
