Mine has died twice now. If you turn it on its side, power button facing up, press and hold hard for up to a minute. It will turn back on. The first time it happened I put it on the charger. Only the blue notification light worked. Nothing else. The second time my daughter was on the phone with me. She hung up. Then, nothing. Not even the slowly flashing notification light. Follow my steps above, it will work. Btw.... tell samsung I want an SD card slot and a removable battery. Clouds are hackable and I want an easier way to reset the dang things. I expect better for $600 dollars when it'll be 100 by next year. CROOKS! J/S
