Charge 3 won't stop vibrating and flashing between screens

[sgamper2007]

Screen flashes continuously from clock face to notification/screen wake and vibrates.  Holding button down does not restart and unable to get to reboot functionality.

You can try to let the battery flat and then wait for a day, then try to start again. If works for me.

but then It failed on one of failed, another back to normal.

I contact fitbit to ask for a replacement

I have the same problem and have to restart my charge 3 every day or two I have done all the things they told you to do but no difference

I am having the same problem with my charge 3 flashing vibrating and I can’t get to ge setting icon to manually reboot. I did manage to change the clock face but it is still behaving the same way. What button do I push when it is plugged into the charger? The button on the side wouldn’t be accessible.

Same problem here. Flashing and vibrating. Restart does not help. Synch impossible. Unbelievable product.

I've tried all these ideas yo get my Charge 3 to restart and stop flashing and vibrating.  This has happened 2 times before.  I've had this replacement a few months.  It's now doing the same thing add the previous 2.  What the heck? Poor quality and I got no where as I was chatting with "support" this evening.  "Karen" actually just logged off in the middle of the steps I was providing to her.  I think this company is a joke.  Poor quality products for the price and horrid customer service.
