I had the same thing happen to my Gearfit 2 twice now. The first time I followed the instructions below and it fired back up, and I had to perform the Soft Re-start. This time it would not power up no matter how long I depressed the power button.
So I put the Gearfit 2 on its charger and then pressed the power button and held it down. It took about 12-15 seconds and then came to life.
The interesting thing thing is, I always power mine down when charging. When I powered it down it still had 42% battery life. Now it is totally dead. What happened to the charge it had?
