Check the hardware problem of the mobile phone.
First of all, you need to confirm whether there is a hardware problem with the mobile phone. Turn on the phone selfie mode and observe whether the front camera is skewed. If the camera is not skewed, then the problem may be a software problem, which can be solved by restarting the phone or upgrading the system. If the camera is really skewed, it may be a hardware problem and needs to be repaired by Apple.
Using calibration tools
If it is confirmed that it is a software problem, we can use Apple's own calibration tool to solve it. Open the settings, select the camera, find the "calibrate camera level" option, and follow the prompts to calibrate. If the calibration is successful, the front camera will be readjusted to the correct position.
Manually adjust the camera.
If the calibration tool does not solve the problem, we can try to adjust the camera manually. First, find a flat surface and put the phone screen face down on the surface. Then, gently press the camera with your hand and slowly adjust it to the correct position. Be careful not to use too much force to avoid damaging the mobile phone.
The above is the solution to Apple's front face, and I hope it will help everyone. If the above methods can't solve the problem, it is recommended to go to Apple for official after-sales maintenance.
