I don't know how it happened. I didn't stick it up. I used it for a week and found that the earpiece was curled up next to it, and then I saw a method on the Internet, perfect solution!

 

Take a lighter or a hair dryer, heat it in the curled side, then press it tightly for a few seconds... perfect! Note: The lighter is not directly baked, just heat it!
