Lets assume we have a call going on between person A, B and C. Person A (close to the speaker) and person B(bit far away from the speaker) of nothing phone 2a, person C is at the receiver end of some-other device. Person C holding another device is not able to listen to the voice of person B (far away) but person C can listen to the voice of person A. Person C is not able to understand any conversation from person B due to the cracking voice. I have tested this scenario with other devices such as iPhone, oneplus all of them are working, I have found this issue only with nothing phone 2a. Please help me to fix this issue.
