Why does Huawei's mobile phone photo flash back when it can't be opened?

Taking Huawei's mobile phone P40 and EMUI 1 1.0.0 systems as examples, the reasons why Huawei's mobile phone camera can't open and flash back are as follows:

Camera license

If the camera cannot be opened through a third-party application, users are advised to go to Settings and search for rights management. On the Permissions tab, click Call Camera/Video Camera to see if the camera permission of the corresponding application is turned on.

There are too many background programs.

With the increase of mobile phone usage time, there will be more and more program caches. In this case, it will lead to slow operation and flashback. You can go to Settings-More Settings-Applications-All, find the software that is flashed or unavailable, and clear the cached data.

Insufficient memory

It may be that the memory of Huawei's mobile phone is insufficient, which leads to the situation that Huawei's mobile phone camera can't open the flash back. It is suggested that users can clear the memory cache, and then turn on the camera of the mobile phone after clearing it, so as not to turn on the flashback again.

Mobile phone kardon

It may be that Huawei's mobile phone is stuck, which leads to the phenomenon that the mobile phone camera can't open and flash back. Users are advised to exit the mobile phone camera and try again.
