In an attempt to enjoy the Jet Black finish while still pristine and perfect, I've been going careless with the new iPhone 7+ for the past couple days and have felt what seems to be fairly significant overheating occurring on the back, top left-hand portion of the phone nearby (and also including) the camera area. It comes and goes very quickly - the camera bump and surrounding area will become noticeably hotter compared to the rest of the phone along with prominent "hissing" if I put my ear up to the area. Putting the phone to sleep for a few minutes appears to bring the phone back to normal operating temperatures. It's so short lived, that I never even experienced the issue until using the phone without a case the past two days. It appeared to be linked to use of the camera based on what I've been able to gather empirically, but most recently occurred after performing a network settings reset (which also reboots the phone) which makes me wonder if it's more broadly processor/RAM related. The last thing I want to do right now is wait months for a replacement JB 7+ phone, but given recent smartphone affairs with overheating, I also don't want to take any chances either. Have others experienced this same problem?
