I purchased my iPhone 13 Pro Max in late September. It is now mid December and the phone is beginning to have an odd speaker issue. The front speaker, (the one where the notch is located), is crackling. It only does this at higher volume. I noticed this last night, which raises the question of whether this is an issue with the device or the software. I say this because I updated my phone to iOS 15.2 last night. What do you guys think? ?
