The Symptoms
The first step to knowing if your iPhone has loop disease is to know the symptoms. While it’s generally an audio-related bug, loop disease can unfortunately be tied to a range of symptoms that can impact how you use your device. Be aware if you start noticing any of these on your own iPhone 7 or 7 Plus.
- Poor audio quality across iOS. More specifically, it could cause crackling or just generally strange audio and speaker behavior.
- Inability to be heard on phone calls, or other issues with the device’s microphone.
- A grayed-out speakerphone icon during phones call.
- Certain audio-based apps, like Voice Memos, being inaccessible. (Also grayed out.)
- Random but consistent iPhone freezing.
- iPhone getting stuck on the Apple logo during boot up. Sometimes indefinitely.
