Samsung's second-generation smartwatch, released in April 2014 and powered by a Tizen-based OS. Model Number:SM-R380.
Every time I try to boot up my camera, an error message pops up. I know it's not because of low energy because I did charge my Gear.
You might be out of memory on the Gear from taking too many pictures. Try deleting a few pictures or other files to free up some memory.
If it is still not working, you may want to try replacing the camera.
