As per an official statement from the South Korean firm LG, the G Watch R that was launched without Wi-Fi support might receive a Maintenance Release in the third quarter of this year bringing the Wi-Fi connectivity support to it.
This addition of Wi-Fi support to the smartwatch will let cloud sync over Wi-Fi for Android Wear devices. This feature will connect the smartwatch and smartphone via Wi-Fi to enable syncing data between the devices.
The statement mentions that the engineers are working on the patch for the LG G Watch R. There is no claim about the Wi-Fi support for the original LG G Watch. Though the roll out will happen in Q3 that is a bit late, it should be great news for the owners of the G Watch R.
