iPhone can't answer the phone is Trade data-driven transport mode selectiona common problem, which brings great trouble to our daily life, whether at work or in life. Especially in important meetings or emergencies, the failure of iPhone to answer the phone may have very bad consequences for us. What should we do when the iPhone can't answer the phone? First of all, we need to understand the possible reasons why the iPhone can't answer the phone. Usually, there are several reasons for this problem. First of all, it may be because your iPhone is in the "Do Not Disturb" state, which makes it impossible to answer incoming calls. Secondly, it may be because there is a problem with the sound of your iPhone, or it may be due to a speaker failure, or the sound is muted, or the microphone may be faulty.Third, it may be that you can't answer the call because you don't operate the notification bar of the incoming call correctly. After understanding these reasons, we can adopt different solutions to solve the problem. Solution 1: Check the "Do Not Disturb" status. If your iPhone is in the "Do Not Disturb" state, you will miss all incoming calls, even if they are very important. Therefore, we should check whether our iPhone is in this state in time. Open the control center and check whether the "Do Not Disturb" function is turned off. If you find that this switch has been turned on, you need to turn it off. Solution 2: Check the sound and notification settings. If your iPhone can't answer the phone, you need to check whether your voice is working properly. You can open the music player or other applications to test whether your speaker makes a sound normally.If you find that the speaker is faulty, you need to take the iPhone to the Apple Service Center for repair. If the speaker makes a sound normally, you can check whether the "Mute" function is enabled or whether the sound is turned up. If there is no problem, then check whether your microphone is working properly. If there is no problem with your mobile phone receiver, but the speaker is really faulty, you can also use headphones to answer the phone. After plugging the headphones into the headphone connector, you can answer the phone normally. Solution 3: Check that if the iOS version of the notification center is too old, it will not be connected. Follow the following instructions to view the iOS version. Settings > General > Software Update. If there is an update package, please update the iOS version. If your iPhone is in Do Not Disturb and does not set up a call prompt in the notification center, you may miss the call.Find and set the corresponding options in the settings to ensure that you still receive prompts about incoming calls when you don't disturb. If none of the above works, you can try the following steps: 1. Check the strength of the signal. Sometimes, the telephone signal may become weak due to the network and other reasons. When the signal is weak, our iPhone can't answer the phone. Therefore, we need to confirm that the current signal is normal and stable first. If the problem is caused by the signal problem, you can try again in an open area or a low-low building nearby. Two. Restarting the iPhone and trying to reset the iPhone is also a common way to solve the problem. You can try to press and hold the power button and the Home button for about 10 seconds until you see the Apple logo, and then release the button. This will restart your iPhone and clear any cache and error records.Summary: When our iPhone can't answer the phone, we should first rule out some possible reasons, and then take a targeted solution. In many cases, resetting our iPhone can solve the problem. If the reset is invalid, you may need to go to the Apple Service Center to repair or replace the device. In any case, we need to make sure that our iPhone works properly so that we can keep in touch under any circumstances.
