Alright , so I may or may not have replaced my screen of my iphone 6 (Which is still in warranty) With a OEM . So , erm the phone was working fine until last sunday where it couldn't charge and I sent it in to my local service provider (A.lab, Which it not part of Apple) and they took it in and sent it to apple and ( Yes I Knew this would come but I was hopping they'd close one eye on this &They found the screen to be OEM. When I went to collect , I asked the Counter lady if she I was still eligible for the buying of refurbished iphone as a replacement for this and she said No and that my iphone warranty has been canceled Fast-forward to today, I decided to give apple support a call . To my surprise , my warranty is still valid . My Applecare officer told me to try to get a original apple screen before going in again. It's my best gamble. I Just have 2 qn for all the seniors here : 1)Lets say i buy a defective original IPhone screen and stick it up my phone and send it in , would there be a serial number on the screen for them to trace 2) If its the motherboard issue , Would it still be worth to change it if option 1 fails? I'm Not sure If apple has a record of me changing the screen already tho as A.Lab Sent my phone to them.
