Below is an image. What is that part responsible for?
I'm asking because lately I had some problems with the GPS in my Galaxy S3, and I found out this sticker doesn't stick well. I think, but am not 100% sure, that when I hold it with my finger, the GPS works better.
I've been in a phone repair center, and I've been told that this is not related to the GPS, and that the GPS antenna is in the right, but they couldn't answer as of what this part is for.
