This information is applicable to all the realme devices.
Noisy surroundings and blocked microphones may result in poor recording quality. It is recommended that you perform the following troubleshooting:
1. Check if the recording environment is normal.
If the lock is too noisy in the environment, or the microphone is too far away from the phone, it will affect the sound quality of the recording. It is recommended that you record in a quiet environment and as close as possible to the sound source.
2. Check if the microphone is blocked.
The occlusion of the microphone will directly affect the quality of the recording. Please make sure that the microphone is not blocked when recording, such as accidentally holding it down by your fingers.
You can also check the microphone for dust or other foreign matter. If it is, please clear it and try again.
3. Check if the microphone is normal.
You can confirm whether the sound heard by the other party is normal by calling the phone. If it is not normal, it is likely that the microphone is damaged. You can contact realme customer service directly for after-sales processing.
If the above does not solve your problem, please go to the nearby realme service center for testing.
