Try Software Fixes, Because It Isn’t Cheap to Repair
Of course, you may not actually be experiencing loop disease on your own device. Certain symptoms may actually just be caused by software bugs or other routine issues. Because of that, you’ll want to try the software-based fixes mentioned in slide #4. But if all else fails, it may indicate that your iPhone 7 actually has a loose audio chip.
Unfortunately, a loose audio chip isn’t cheap to fix. According to Consumer Affairs, repairs can cost anywhere from $79 for a “quick fix” to $180 for a future-proofed solution — which could mitigate any risk of loop disease in the future. If your iPhone is still under warranty or AppleCare+, you may be able to get it repaired by Apple for free.
