While compatibility with just the Samsung Galaxy Note 3 and Note 10.1 2014 Edition is one of the main constraints of the Samsung Galaxy Gear smartwatch, this may no longer be the case as Samsung have announced that quite a few Galaxy devices are going to get compatible soon. This includes the Samsung Galaxy S4, Samsung Galaxy S III and Samsung Galaxy Note II as soon as they receive their Android 4.3 updates, which are currently being rolled out in phases. Following these are the Samsung Galaxy S4 Mini, S4 Active, Mega 5.8, Mega 6.3 and S4 Zoom. While the software update will again be released in phases, these devices will begin getting the update by the end of October. Bear in mind though that certain functions and features available for use on the Samsung Galaxy Gear will depend on the tech specs available to each device.
