Hello FatimaFitbit, firstly I wish to point out that on my Fitbit HR I only have 1 x button, not "buttons" as you have asked me to press. After pressing the button a smiley face does appear but the Fitbit does not vibrate and then the smiley face disappears and the screen goes blank. After sometime the smiley face appears again then disappears again. This happens several times until the Fitbit logo and 001 appears again and stays on the screen. I have also tried the steps in the article but as the Fitbit doesn't turn on the steps in the article do not work. This problem started straight after the Fitbit app was updated on my phone.
