I woke up to my watch disconnected from my phone and screen black which made me think it must have ran out of battery. However that's not the case, I try turning it on and all that shows up is the regular samsung logo with"Rebooting..." under it follwed by a black screen (not turning on all the way). It's been this constant cycle and I don't now what to do. It's a Samsung Active 2 watch that I purchased not long ago so for this to happen is unusual.
Thanks for reaching out.
I can certainly understand this frustrations this may have caused you.
Can you send a private message providing the full model code and serial number so I can further look into this for you? http://bit.ly/2GGYul4
