What is the silence of iPhone 4 after receiving SMS?

1, first check whether to switch to mute, there is a control button above the+-volume.

2. If it is not the above phenomenon, check whether the volume is not turned up.

If this is not the case, please carefully check whether the receiver, speaker and recorder are all normal.

4. If none of them work normally, then the voice control part is damaged and needs to be replaced, and the cost is in the range of 50-80 yuan.

5. If only a single component is abnormal, it means that individual components are damaged, and the price of replacing individual components is within 50 yuan.

Maybe your WeChat has information, and the second possibility is that your information is full and can't be displayed.

Solutions;

1. If there is no sound when a phone call or text message comes in, you can check the mute button on the side of the phone to see if it was accidentally pressed.

2. If there is no sound when you make a phone call with headphones, you can check whether you have not pressed the earphone plug to the end. Sometimes the protective case of mobile phone is too thick, which easily leads to the situation that the earphone can not be pressed to the end and the contact is not good.
