The Gear is pretty intuitive, but I thought that it would be a good idea to have one place to find tips and tricks that help us enjoy the Gear even more.
-You can change the settings for the double-tap of the power key by going to the Gear Manager on your phone, select settings, then Double pressing power key.
There are many options to include launching the camera and launching S Voice.
-You can set a pattern lock to keep your Gear secure by going into settings on the Gear and selecting Privacy Lock.
-Double-tap with two fingers on any screen to bring up volume control, brightness control, battery level and Bluetooth status.
-You can set which arm you normally wear your Gear on by going to settings on the Gear, select Sound, then Preferred Arm.
Das has put up many useful tips in other threads. I hope that he and others post helpful hints here.
