While the Samsung Galaxy Gear smartwatch probably offers the most in terms of functionality for any smartwatch currently on the market one of it's main limitations was that it only works with certain Samsung smartphones. This short compatibility list included the Samsung Galaxy Note 3, Note 2, S4 and S3 with Android 4.3 firmware. However, this is no longer the case as Smart Watch Fans have come up with a guide showing how to make the Galaxy Gear smartwatch work with a Nexus 5 smartphone. It may require you to download some files, extract them and rename them, but there isn't any arduous programming or too-technical stuff to do to make it work. Do bear in mind that most of the apps work, except for S-Voice and Weather. Other smartwatch fans are saying that they have also made the Galaxy Gear work with the Sony Xperia Z Ultra, provided that it is the pure vanilla Google Edition version.
