LG -G Watch

Users have complained that the corrosion is causing them
discomfort due to the metal-to-skin contact, as well as problems
 with charging the device; some users aren't able to get their
smartwatches to charge at all. While this seems like an entirely
 hardware issue, LG assures that an OTA software update will
fix the problem. Just how can a software update stop the metallic
 charging connectors from corroding, you ask? Well, the G
Watch constantly streams a current to the watches bottom
conductors - even when the device isn't charging. As a result,
when the watch makes contact with your sweat-covered skin,
 grime builds up and boom, that's where the corrosion begins.
 So what's LG to do? A rep breaks it down: "LG will be rolling
out a maintenance release over the next few days that will disable
 the current when the G Watch is not in the charging dock..
.[this will be] completely safe and unlikely to affect charging.

" If the software update does what LG intends, then the Korean
 tech manufacturer will save itself a lot of money in product recalls.
 The update was pushed out yesterday, so time will tell if this solves
 the corrosion issue and if not, then LG will surely have a lot of irate
 customers on its hands.
