MojoKid writes: The Samsung Galaxy S7 and S7 Edge don't officially launch for a few more days, but some carriers appear to have shipped pre-orders early and some phones are already in consumers' hands. One early Galaxy S7 Edge owner appears to have tested his phones' water-resistance already and uncovered another new feature in the process. The user submerged his Galaxy S7 Edge in water and snapped a photo, then about four hours later plugged the phone into its fast charger and a warning popped-up on screen that stated, "Moisture detected in charging port", and the phone wouldn't charge. The user dried the phone and let it sit for a while, and it eventually started to charge again, but it wouldn't quick charge any longer. Frustrated, the user RMA'd the phone and plans to send it back to T-Mobile. The Galaxy S7 is IP68 rated, which means it is sealed against dust and can handle continuous submersion in up to 1 meter of water. However, the water detection feature that's apparently built into the Galaxy S7 is a good idea. Though the devices are IP68 rated, a few drops of water in the charging port could easily cause a short when the phone is plugged in.
