There is a noise when calling on the Redmi Note 13 Pro

If you hear noise during calls on the Redmi Note 13 Pro, try the following steps to address the issue:
1. Ensure that the phone’s microphone and speaker are not obstructed or covered by a case;
2. Make calls in different environments (e.g., quiet vs. noisy) to determine if the issue is consistent or related to specific conditions;
3. Poor network reception can cause noise during calls. Move to an area with better signal strength and see if the issue persists;
4. Clear cache for the Phone APP;
5. Use headphones or a headset to check if the noise persists. This can help determine if the issue is related to the phone’s built-in speakers or microphone;
6. Try to restart your phone to check if the issue is resolved;
7. Go to Settings to check for and install any available updates, which can fix known issues;
8. As a last resort, you can perform a factory reset. Make sure to back up your data first.
