When i got My glasses, i see a detalle with this; in the first time i try yo turn on, My glasses never turn on (usualy, the glasses says when this turn on), but after a lot of tries, this turn on.

in the rest of the days, i got the same problem, i have dificult to turn them on, but i detect one thing, and is i only have the problem with one side, cause i join to the application, and this notify only detect one side

yesterday, i charge my glasses and turn on without problems, but, suddenly, this turn of without notifications.

after that, i cannot turn on again.

in the rest of the day, i try to turn on them, but i dont have answer from the problematic side, but in the night, i got response from this and can turn on again.
