Samsung released the firmware for the Galaxy Gear (SM-V700), but what’s surprising is that it appears to be based on Android 4.2.2. One of the reasons why the Galaxy Gear is “only” compatible with the Galaxy Note 3 is because of Android 4.3’s Bluetooth Low Energy (LE) compatibility. Now I put “only” in quotes because it was found that the Galaxy Gear is somewhat compatible with the Galaxy S 4 even though that’s not supposed to happen till later this month. We couldn’t understand why, but this probably explains it. Interestingly enough, The Galaxy S 4 has built-in support for Bluetooth LE and that is why it will connect to the Gear.
