Hello everyone, I was using blackberry Z10 and I sold it off and purchased new iPhone 4S 2 days back. Problem is, burning smell is coming from the charging port at the bottom of my phone(it's coming even after I removed the charger) I checked the device, it's original. Running 8.4 OS. I'm lil scared, about this issue. Please give me suggestions. Is this normal or should I do something to avoid this? I'm new to IOS. I'm from India. Thanks in advance.
