Hi Again,
I apologize if something i said was offensive. I myself completely agree that it can be normal, i just want to be careful that it is nothing serious. You are right, Apple is looking into this issue, and posting here was not for attention, it was to discuss what the other fellow users in the Apple family are doing to get it rectified. I have been using iPhones every iteration since the iPhone 5, so i know its a good piece of hardware.
In many places phones are being replaced, it doesn't bother me if they replace it or not, i just want to have a piece of mind that it's safe to use. Like we all discusses before, it can just be a fan like mechanism. Anyway, tomorrow is my call with Apple senior rep, will update it here.
This discussion was not opened to drag Apple's attention in anyway, the best company out there which with exceptional customer satisfaction so i know I'm in good hands.
