Hello If I press the post button on my OontZ Angle 3 I get a red light that flashes repetively in groups of three. If I hold the power button down the speaker works (but the red light keeps flashing). As soon as I let go of the button the speaker dies. I have tried charging with multiple cables. I have tried to find the reset button through the auxiliary jack, but I don’t feel anything in there that feels like a button. Any ideas? Update (05/25/2018) Has anyone successfully found the reset button?

What I have found is that the reset switch is in the auxiliary in jack. Use a straightened paper clip a carefully push it into the “AUX IN” jack until it makes contact with the micro switch.  Gently push and it will release the switch which should reset the speaker.
