Iphone screen cracked!!?
If this was a defect on the part of Apple, you can probably take it to the closest Apple Store (no idea where you would find one sorry) and they will tell you what can be done as far as replacing the unit or repairing it (if at all even possible). If it was not a defect on the part of Apple, meaning it was dropped or otherwise broken by you or someone else, then Apple will do absolutely nothing other than possibly repair it for a rather hefty fee (probably almost as much as getting a new iPhone). This product is essentially only repairable by Apple Inc, if it is even repairable.
I don’t know where you can get your phone fix in Chennai India, but I can tell you this, you can’t fix it you have to get a new one. If you have insurance on it you can get a new one a lower cost if not then you have to pay full cost. Sorry I really can’t be of any real help to you. Good luck and take care….Keep the Faith….Peace….cya….
