How to deal with the focus blur of mobile phone

There are four main reasons why it is difficult to focus when taking pictures.

1. For some solid objects, such as pure white wallpaper. The mobile phone focusing system will: "circle" can't find the focusing subject. The solution is to look for obvious lines or color blocks of other colors in the solid color background, and then move the mobile phone to shoot after focusing, or put an object on the solid color background and move it to shoot after focusing.

2. The main body is not prominent enough and relatively small, so the mobile phone is not easy to focus. The solution is to get close to the camera and enlarge the subject. If you can't get close, choose manual focusing.

3. Too close to the subject, beyond the nearest focusing distance of the mobile phone, unable to focus. The solution is to distance yourself from the subject and shoot again.

4. For high-speed moving objects, if the subject moves very fast, it is difficult for the mobile phone to focus. The solution is to determine the place where the subject will pass in advance, focus on that place, and wait until the subject arrives before shooting.
