I've noticed that, some say it comes from humidity or sweat. That's BS, becAUse it makes a lot of difference on our cost, if we've had no water issues (liars excepted, they can go to hell). If this happens a lot, we should do a Class Action lawsuit against those carriers who put them in their phones, and the manufacturer. I have seen them lie, and I'm scrupulously honest. I've even seen conflicting indicators within a QUARTER INCH OR SO.
