Realme Flash version, if you have any questions on the phone, answer the phone clearly.

1. First of all, the noise reduction microphone hole at the top of the mobile phone is relatively large. Tape it to the noise-reducing microphone and it will be solved.

2. Secondly, make sure that the sound hole of the receiver or speaker is not blocked by foreign objects, and it is suggested to clean it as much as possible.

Finally, try to call other numbers to see if the same situation will happen.
