I bought my phone two years back and using it since then. It was my second iPhone which made me comfortable to use it again. After some time phone had some heating issues which at first I thought quite normal. But the issue remain same while gaming and doing multi tasking work. I was also disappointed with the charger the company provided with the phone it was of less wattage and it slow charge my phone. Then I have to carry another power bank with me of high output voltage!. And now due to heat some of my components like my GPS and back microphone stopped working. My phone also fell on the ground from half feet and my screen gone fully. I went to service center which was too far away like 120 kms from where I bought the phone.
This made me mad sometimes and now I wish I could have invested in any other phone instead of buying an iPhone!
