i have the same problem dude
my indicator is red and i make sure to keep my tp2 away from water, but somehow the indicator still triggered on me
i dont have a sprint store within 150+ miles! so my only option is to send it in to sprint for a replacement. if they say something about the indicator, ill explain to them i make sure not to take the tp2 near water and ask if they can take a closer look at the phone (at the other indicators)? that sounds like my only option besides asurion (last resort of course)
