What is the reason why Apple's mobile phone speaks intermittently?

1, the Apple handset is blocked by foreign objects, or the internal hardware of the handset is damaged, which can be detected by headphones;

2. Apple's mobile phone operator's network is not smooth, so you can change to another operator's network test;

3. Apple's mobile phone system is disordered, resulting in intermittent voice of Apple's call, which can pass the brush test;

4. The audio IC on the motherboard of Apple's mobile phone is damaged, resulting in intermittent voice.
