Fix for the autofocus problem?

I really don't want to deal with customer service and try getting a replacement since I've had this for about a year and rooted it asap. I know this phone isn't that repairable according to ifixit, but there's gotta be something I can do. I hate being able to only take selfies. :(

If you don't know what I'm talking g about search Google for the autofocus problems with this weird vibrating thing. It's all ****ed basically.
