Samsung Galaxy S7's Moisture Warning Prevents Charging When Wet (hothardware.com)
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.
So it would never quick charge again or it just wouldn't in the short amount of time the user tested it within, which really isn't stated. For all we know this could have been solved by turning if off and on again and it's something a software/firmware patch can fix.
Indeed.
He could have asked technical support "Hey guys, everything is cool, but can you take a look if you can make the quick charge work again? It's just a nice feature to have and the phone happens to still be under warranty. Thanks!"
Instead, he got frustrated and returned the phone and plan.
First world problems...
