I understood just fine. Doesn't mean it's right to keep returning a phone because you think one chip is better than the other or because you keep staring at a faint blemish that all of our phones have. Want a near perfect to perfect screen? Buy a phone with an OLED display because there's not an IPS panel on the planet that is perfect.Come on that's not what I meant. Let me explain so you will understand. Apple will always have replacement stock so if you get a jacked up phone and want to keep it fine. Others who want to get their moneys worth will swap theirs out until they are satisfied.
