Yes the S Pen needs to be pressed harder for the erase to work. I don't know why that is. Overall i'm a little disappointed with the S Pen on the S22 Ultra. The notifications are also way too small in text to read properly at first glance, but i believe that is a One UI 4 problem. I saw another thread of people having the same issue. My S Pen on Note 10+ just disconnected automatically and would mot reconnect now. Have ttied to restart phone many times and clicking on "tap here yo connect it again" does not work. Removing the Spen from the slot does bring up menu amd works finebut Still keeps on showing S Pen disconnected. A Under Mouse, keyboard, & pen, look for Surface Slim Pen or Surface Slim Pen 2. Windows 10. Select Start > Settings > Bluetooth & devices. Look for Surface Slim Pen or Surface Slim Pen 2 to see how much battery is left. Surface Duo 2. For info on checking your pen's battery on this device, go to Connect Surface Slim Pen to Surface Duo. Go to settings, general, reset and reset all network settings. Try disabling WiFi for a bit, the 2.4Ghz range can be shared between WiFi and Bluetooth so removing one variant can help. You can also unpair the Pencil and pair it again. Hope that solves it! .
