Uh Oh!, it seems that LG is under fire from early adopters who bought the G Watch, who are complaining from issues with corrosion of the metal contacts on the charging pins, particular after exercise and sweat.
The sweat from some smartwatch wearers is forming an oxide coating on the pins because of the salt it contains and creating some issues and skin irritation.
LG has announced that it is releasing an over-the-air update which prompts the watch to cut power from the charging pins when they aren’t in use, which prevent the chemical reaction from occurring and stop any additional corrosion.
If you’re one of the owners of an LG G Watch, make sure to update the software to build number KMV78Y (which replaces the original KMV78V).
Recently it has come to our attention that a small number of G Watch devices have been reported to have developed discoloration and residue buildup on the terminal pins located on the back, said a member of the LG support team, While completely safe and unlikely to affect charging, 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.
