Open the case of your mobile (cell) phone. Do you see a round white sticker, similar to that in the first photo below? […] This is a water damage sticker, which changes colour if moisture gets into this bit of the phone, and will be used to void your warranty if your phone stops working for any reason. […] A single droplet of water placed on the sticker turns it bright red (in the case of my phone, anyway):
Someone [ahem] at Blend should check this out. But I’m not going to name any names.
It was Joe.
