People who use iPhone 8/8 P say that the call volume is low and can't hear clearly. After all, the call function is the most basic function of the phone. If a mobile phone can't call, this is no need to call it a mobile phone. To help solve the problem, below are some solutions.
First of all, you need to check what has caused the problem:
Step 1: Make sure if your volume is low or others are low. Then check if you set the call volume low.
Step 2: The volume is low when you listen to others. Maybe there is a problem with someone else's microphone (or his call volume setting); your receiver is blocked such as protective film on the receiver; the signal is not good; your mobile phone setting problem
Then, you can troubleshoot by the following steps:
On the side of the Apple 8 mobile phone, press the volume button to increase the volume;
1. Go to Settings > General > Accessibility
Go to Settings > General > Accessibility > Audio/Visual to turn Phone Noise Cancellation off. The volume should be up.
Insert Apple’s original headphone during the call and then unplug it. See if you can solve the problem of low volume. If you still can't solve it, please resort to the next step.
If the phone sound is still abnormal, the system may have an error. You can try to restart your mobile phone to see if you can resolve it. If you can't solve it, you can try to restore your mobile phone to factory setting;
If you hear noise when you use one of the APP, you may try to update or delete the current mobile phone software.
