This is only curiosity, but I tend to think of iPhones as being very fragile ..people complain about all sorts of issues, and im one of those people that REALLY baby their new iPhone for the first few months. Basically I had to search for my iPhone as I couldn't find it anywhere, after calling it for 10-15 mins and carefully listening for where the vibration was coming from, I found it but now I am just here tryna see if the vibration works as it should or if I have damaged the motor inside as it did vibrate for nearly 15 minutes, how common is a vibration motor damage?
