Watch 3 black screen

[Ghostsmom]

My galaxy watch 3 shows full charge but will not start up! Absolutely no damage, only had it for 4 months and it decides to not power up. Is this a power up issue or firmware issue? Ive tried hard reset both on and off the charger. Come on guys please tell me y'all have a better suggestion than a $200 "maybe*!

I highly recommend taking your watch into your local Samsung authorized service center, like uBreakiFix, for further evaluation. Diagnostics are typically free. They will be able to tell you what went wrong and provide you with options for either repair or replacement.

Hey there, thanks for reaching out, and I am sorry to hear your Watch 3 has a blank screen despite being fully charged. There are several reasons why the Samsung smart watch display cannot be adjusted and the screen appears darkened or gray. Both issues can be caused by an accessibility setting, Outdoor mode, physical damage to the watch, a third-party app, or outdated software.

As @VerbumVeritum suggested, since you have already even went so far as to reset the Watch, service may be the best bet.
