Help Samsung Galaxy S4 Rear-Facing Camera Lens Cover

[NicholeD]

Hello all! I'm new here.
I'm here to ask about my Galaxy s4 rear facing camera lens cover. The other day I was taking a photo of something and realized it was blurry. Sometimes the camera gets smudged so I went to wipe it off. When I felt it, it was cracked! Blarghhh.
I took the broken pieces off with a pair of tweezers. The camera worked fine without the cover.
About 20 minutes ago I went to take another photo and it wouldn't focus at all. Is this something to do with the camera or the cover? And is this something I can fix easily? Or should I take it into the shop? Thanks!

Also; should note that I am going to hawaii in 2 weeks and my phone is the only thing I have for photos.

How about replacing a camera module? I think you can buy one online for less than $10 and you can replace it by yourself; https://www.youtube.com/results?search_query=galaxy+s4+rear+camera+replacement
