LG will be rolling out an update for its smartwatch in response to reports that the charging pin was causing discomfort to users.

Wearers of the watch will be able to turn off the charging pins when it is not connected to the charging cradle, following complaints the pins were becoming discoloured.

The issue could be due to the result of galvanic corrosion, a chemical process that occurred when the metals comes in contact with sweat.

An LG spokesman told Android Police: "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.

"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.

"The maintenance release will be rolled out automatically over-the-air to all G Watch owners. We thank G Watch users for their patience and apologise for any inconvenience this may have caused."

The technology site also claimed that the statement from LG has been confirmed by Google.
