I have an iPhone 7+ where the headset speaker volume is super low (the speaker above the screen)... actually when playing music, no sound comes out from it at all. Just wondering if they usually repair the speaker or do they usually replace the device? I had this problem on a 6s plus. And they replaced my device. But at that time, the store was about to close and I just had a feeling that they just didn't want to add anymore work. Just wondering how do they usually handle this problem.
