Nexus 4 Issues


I want to buy a nexus 4, but I'm concerned about the issues I've seen:

-Yellow screen (Is it a screen proplem or something related to the adhesive (and will disappear)?)

-Overheating (the problem is the cpu or the battery?)

-Is the camera purple flare too intense? Will it be solved soon?

-The mic is not so good

Please, tell me what you know to help me!
