If you’re iPhone has been in the rain or if you accidentally spilled a glass of water over it, you would probably be interested to know if any of the hardware inside has been damaged. Even if it was just a one of clumsy occasion you would still want to know if you’re covered by the warranty if anything bad happens.

Well recently Apple updated their guide on “how to verify iPhone hardware is working correctly”, and in this article the section on liquid damage was updated.

For those that may not have been aware, it turns out that Apple implemented an indicator into the iPhone located at the base of the headphone jack. Normally it is just white in colour, but if half of the dot becomes red or pinkish in colour then the resulting repair that is needed will not be covered by the warranty. Apparently the red or pinkish bit indicates that the iPhone has been submerged into liquid / water significantly enough to cause some kind of hardware problem – so if something similar has happened to your iPhone before, better check your dot now!
