I've noticed a really infuriating bug in the AoD, it randomly turns off on it's own. I think Samsung made the sensors super sensitive by accident. Please look into this bug and fix it in the next update.
Hey @Yoshi, to help us troubleshoot, could you please submit a device error log when this happens again? From the Samsung Members application, tap the “Feedback” icon. Tap the Pen icon and then submit an “Error report”. Thanks!
