Hi, thank you for your reply. Tapping app icons does nothing. Dragging or tapping on the home page does not lauch the air command menu. In brief I get no reaction from the tablet at all, not even if i press the button on the S pen. I lost the original original pen and bought what i believe to be a new genuine replacement on Amazon. It had the correct logos and looked identical to the origin pen and did initially work perfectly. I have been in Hospital for 9 months and the S pen lost its charge. I am trying to recharge it. I have read that the magnets in some tablet cases like mine can interfere with the magnetic flux from the screen that charges the S pen. So i have removed the case and now wonder where is the best placeto rest the S pen for charging.
Best wishes Martin
