Where is this rectangular rubber with groove be placed in iPhone 4S?
I opened up my Iphone 4S to replace the Home flexible circuit.
I found that one black colour rectangular rubber with groove dropped out but I do not know where it should be placed in the Iphone 4S?
It is about 8mm x 2mm.
I uploaded the photo of the rectangular rubber to this website: https://s4.postimg.org/8dqohvlwd/Rectang...
Can anyone advise where should it be placed inside the Iphone 4S?
