Default [Q] Possible Problems To Look For?

Hi everybody. I'm receiving my Verizon LG G2 tomorrow (12/4) and am planning on rooting it. I was wondering if there is anything I should look for problem-wise before I void my warranty so I can return it for a non-faulty G2. I plan on testing out the battery for a day or two to make sure it isn't faulty and to test the GPS as well. Is there anything else I should look for so I know my phone isn't a faulty one?
