Galaxy s4 water indicator stickers are in two locations that we can see without disassembling the phone. The battery has a white sticker that will be red if damaged. The phone has a small hole in the bottom right corner of the battery compartment where there will be either an orange or light pink sticker. I called at&t with 3 different warranty phones that were sent back till I finally got a competent customer service representative who researched the issue. The sticker will be pink or orange for normal, blood red for water damage. If you have issues with at&t about this, insist that they research or call Samsung about this issue. Good luck and god day.
