iPhone 15 front speaker issue

Hi bro i have recently purchased iphone 15 in that im facing front speaker issue. While answering the call the opposite voice is breaking and not clearly audible, then if I change to speaker and then turn to front audio it working fine. Don’t know whether it is network or my speaker issue. Could you pls advise me on this?

hello bro, its important to check once with apple service center as its new iPhone and still under warranty. if its network issue, then you will be seeing 2 or 3 signal bars and issue gets fixed when we are in full coverage area or rarely happens in particular area due to network congestion.

Which gets fixed automatically in a week or two time normally.

also if signal strength is full and to check whether its software issue or device issue, make sure iOS 17.4 updated and perform “settings - general - reset - reset network settings” once. then check with any phone call.
