Permanent smudging (spot) on the glass topic

Device #1)

I just got my S4 and it appears there is smudging around the home button, where my thumb presses it. I don't use a screen protector but this has nothing to do with that. It is like a grease spot that doesn't come off. Anyone have this before? Should I return it?

** I went to the Sprint store (within my 14 days) and they exchanged my device. **

Device #2)

I am kind of worried this is going to happen again. Has anyone seen this before?

Blue spot on nexus 7? topic

I was looking at other threads that had similar issues, where there must have been too much pressure applied to one spot on the screen, thus resulting in a blue spot. My question is, if I rma, will they replace the tablet completely? It's pretty annoying but at the same time id rather not have to put all my apps and data back on the new device.
