What is the problem with the flashback when the phone camera app opens

Causes of flashbacks and how to deal with them.

Usually in the process of using the software, some junk files will be generated, and if you do not clean it up for a long time, the phone will become more and more stuck, and there will also be flashbacks.

Go to Settings Apps - All - Find the app in question and clear the data or cache. (Note: Clearing data will erase the app's personal settings, account information, etc.) )

2. There are too many running programs.

If you don't set it up, a lot of software will run on its own, and too many background programs on your phone will cause you to run out of memory, which will cause the app to crash. If there is a software crash, you can clean up the memory before trying again.

4. Application version issues.

Hello, if the phone camera always can't be turned on, and there is a flashback, it is recommended that you restart the phone first. Eliminate the occasional abnormality in the system, which causes the camera program to not start normally, and see if it can return to normal after restarting.

If it still doesn't work after restarting, it is recommended that the landlord can enter the settings of the mobile phone. Then find the option of app management in the settings, and then find the camera program after entering. Click to enter, and then clear the camera's data, after resetting the camera data, you can basically restore the camera to its factory state, and see if it can be solved after resetting the data.

If the landlord still has no way to enter the camera normally after clearing the camera's data. In this case, it is recommended that you can back up the important data in your phone and then factory reset your phone. Let's see if it can be solved, after the factory reset, don't install some software first.

Test the camera separately to see if it turns on properly. In this case, it can be completely excluded from the system. And you can also rule out whether some third-party software has caused a conflict between the system or the camera, causing the mobile phone camera to be unable to use normally.

But if the landlord passes the above steps, there is still no way to solve the problem like flashback. In this case, it is also possible that the hardware of the camera is faulty, and then the camera program cannot run normally, it is recommended that you check whether there is any problem with the hardware of the mobile phone at that time.

Some applications may not release the camera in time due to their own design reasons, such as flashlights, *** scanning and other programs. You can close camera-related apps before entering the camera attempt.

If you can't tell what app it is, you can restart your phone and try again.

2) Clear camera data.

3) Use the "Smart Detection" feature to detect the camera.

Taking the mobile phone as an example, the solution to the flashback if the camera can't be opened is as follows: 1. There is too much cache garbage, and some junk files will be generated in the process of using the software.

It may be that the battery of the camera is not working, and replacing a battery in the humidity should be able to support the camera's system to start directly, and the battery is insufficient, which will cause this flashback, and the system inside the camera is damaged.

Check the third-party application permissions If the third-party application cannot open the camera, we recommend that you go to Settings, search for permission management, and on the permissions tab, click Call Camera Camera to enable the camera permission of the corresponding application.

The camera can't be opened, and the flashback is generally due to the occupancy. Let's see if there are any other software occupied. More often than not, the problem of the phone itself, the camera itself is out of order, and if you solve it yourself, then you can only flash the phone or restore the factory, which can be restored.

Go to your phone's settings and find the app Find the app camera and tap to clear the camera or cache. Too much cache junk Usually in the process of using the software, some junk files will be generated, and if you don't clean it up for a long time, it will cause the device to get stuck more and more, and there will also be a flashback.
