There is a round indicator of some sort under the battery cover approx 3/16" of an inch in diameter. It is located to the left of the "Do not dispose with household waste" icon (looks like a trash can with an X over it. The indicator appears white with red "X"s; I believe it has been this way since the phone was new, but I can't be sure. What does this indicate? enter image description here

    I'm not sure asking about a sticker counts as an Android question, but others may disagree. May 9, 2011 at 23:40
  • Could be a warning to recycle the battery instead of throwing it away.

  • I'd agree with @Matthew regarding this - it's a battery question, not an Android one. May 10, 2011 at 0:01
  • To be clear, this is not part of the battery, it's on the phone body, but you have to remove the battery door to see it. It looks like more than a simple sticker... there is a hole in the body of the phone specifically to reveal a view of it. I'll post a photo shortly.

Perhaps it's a water damage sticker -- it might go more red if water gets on it, or something.

    +1 Looks like a water damage indicator, it's that same shade of light-ish red as the cross-hatching on the water damage indicator on my company phone.

  • Yes, it's a water/moisture damage indicator.

  • Searching on "droid water damage indicator" shows lots of sources that agree. Apparently it turns solid red if it gets wet. Accepting answer. Thanks.
