Why did the Huawei phone fail to switch to the telephoto lens?
In a dark environment, when shooting close-up targets or shooting through glass, the Huawei phone may fail to switch to the telephoto lens. The reason was as follows:
- In a dark environment, due to the small aperture of the telephoto lens, the amount of light entering was small, and the sensitivity of a single sensor was much lower than that of the main camera. Therefore, sometimes in a specific dark light, the photo effect of the telephoto lens might not be as good as that of the main camera with super sensitivity. At this time, the digital zoom lens had better shooting effects, and it might not be switched to the telephoto lens.
- The telephoto lens was designed to shoot far away, so it was difficult to see close. When the distance was close, the camera would switch to the main camera, using digital zoom or multi-shot hybrid zoom, which would be worse than optical zoom.
- When shooting through the glass, the laser or TOF of the camera would detect that the nearest blocking object was less than the closest focusing distance of the telephoto lens (usually about 1.2m), so when it was greater than or equal to the default optical zoom factor, it might not switch to telephoto. The camera would automatically select the appropriate lens matching strategy based on the brightness around the focal point to achieve a better multi-camera hybrid zooming effect and maximize the ability of each lens. Manual adjustment was not supported. When the zooming ratio exceeded the hybrid zooming ratio, the camera would be forced to switch to the telephoto lens (refer to the maximum hybrid zooming ratio marked on the official website for the specific ratio).

Why did the Huawei phone fail to switch to the telephoto lens?
There may be the following reasons for the failure to switch the telephoto lens of a Huawei phone:
1. Because the aperture of the telephoto lens was small, the amount of light entering was small, and the sensitivity of a single photo element was much lower than that of the main camera, the telephoto lens might not be able to switch normally under certain dark light.
2. The telephoto lens was designed to shoot from afar. When looking at a close distance, it might not be possible to switch to the telephoto lens. If the distance was close, the camera would switch to the main camera. At this time, using digital zoom or multi-camera hybrid zoom would be worse than optical zoom.
3. The laser or TOF of the camera would detect that the nearest object blocking the lens was less than the closest focusing distance of the telephoto lens (usually about 1.2m). Therefore, when the optical zooming ratio was greater than or equal to the default optical zooming ratio, the lens might not switch to telephoto.
4. The camera would automatically select the appropriate lens matching strategy based on the brightness around the focal point to achieve a better multi-camera hybrid zooming effect and maximize the ability of each lens. It did not support manual adjustment, which could also cause the telephoto lens to fail.

The phone camera can't switch to the two-way camera
If the iPhone 12 Pro couldn't be switched from 1x to 2x, it would be stuck, but it could be switched from 1x to 0.5x. After exiting the camera from 2x, the screen would be black, and the malfunction couldn't be fixed by repowering the phone and installing iOS14.4. You could go to an Apple authorized repair shop to check and deal with it. If the white balance of the iPhone 11 changes when the camera is switched, this is a normal phenomenon. Usually, Apple will do optimization on the camera so that the color difference can be corrected quickly. If it is found to be significantly inconsistent, you can try to update the system or manually adjust the white balance settings. As for the other phones that did not mention the relevant situation, I'm sorry, I can't give an accurate answer.
