missing smd after crystal oscillator replaced necessary?

Just swapped crystal oscillator on an iphone 5c to fix random time issue, i managed to loose a microscopic smd next to it and failing to find and fix it back to the pads i turned it on and it all works fine now....so can i assume that missing part will eventually cause probs?

You should probably take a photo of the missing part and look it up in the schematics / board view.
