When Samsung launched its Galaxy Gear smartwatch last month, it could only work with the Note 3 and Note 10.1. The Korean company announced on Wednesday that the Galaxy Gear will be compatible with more devices including the Galaxy S4, S3 as well as Note 2, after a software update to Android 4.3. It seems like Galaxy S4 owners in Germany can already use the Galaxy Gear with their mobile phone, as Samsung notes that the software update first landed on Galaxy S4 in the European country this month. The Galaxy Gear will be compatible with more Galaxy devices — including the Galaxy S4 mini, S4 Active, Mega 5.8, Mega 6.3, and S4 Zoom – via a separate software update that will kick in at the end of October, though the schedules for software updates will vary by device, country and carrier.
