What if the camera behind the mobile phone is blurred and always out of focus?

If you use Huawei mobile phone, the phone can't focus when taking pictures. You can check the operation by the following methods:

First of all, ensure that the camera's focusing function is normal.

With the camera facing the subject, adjust the shooting distance (wide angle is about 0.5m or 1x, telephoto is 2m), select MF (manual focusing) as the AF parameter, drag the slider left and right, back and forth, and observe the preview interface.

If the preview changes from clear to fuzzy, and from fuzzy to clear, the camera's focusing function is normal. Please continue the investigation according to the following situation.

If the preview interface is always blurred, it may be that the focusing function of your mobile phone is not normal. It is recommended that you back up important data in advance (third-party applications such as QQ and WeChat need to be backed up separately), and bring the purchase voucher to the nearby Huawei customer service center for more help.

Second, make sure that the lens area or laser parts of the camera are not dirty or blocked.

1. The lens and its surroundings should not be blocked or pasted (including transparent).

2. Some non-original protective covers will block the laser (including transparent).

Third, different scenes focus in different ways.

1. When shooting a face, there is no focus frame in the preview interface. At this time, whether the focus is completed is judged by whether the preview screen is stable.

2. When shooting an object, when a focus box appears in the preview interface, and the focus box turns orange or white, it is considered that the focus is completed.

Fourth, confirm the choice of manual focus or autofocus.

1. After recording starts, if you click on the picture to focus, the camera will lock the focal length to ensure the stability of the scene. Then, no matter whether the picture or position changes, it will not focus automatically, and you need to focus manually.

2. If you need to focus automatically all the time during the recording, please don't click on the screen to focus after the recording starts, and try to put the target you need to shoot in the center of the lens clearly.

Fifth, the focus of special scenes is slow.

1. The closer the object is to the mobile phone, the greater the distance the lens in the camera needs to move, the longer it takes and the slower the focus will be.

2. If the color and characteristics of the subject are similar to the surrounding environment, the camera needs to focus repeatedly to determine the focus, and the focus will be slightly slower.

Sixth, ensure sufficient light.

1. When focusing, the camera needs to compare the details and contour information of the object. If the ambient brightness is low, these features of the object are not obvious, which will affect the camera's judgment of the distance of the object and slow down the focusing speed.

2. It is recommended to choose a scene with sufficient light when taking pictures.

Seven, keep the phone stable.

When the phone shakes or the subject keeps moving, it will affect the focusing function. Please try to keep the phone stable when shooting (use a tripod to shoot if necessary).

Eight, ensure that the camera cache space is sufficient.

Clear the camera cache and restart the phone. Instructions for clearing the camera cache: enter Settings, search into Application Management, search or find the camera, click Save, select Delete Data, and confirm.
