This morning on my Note 10+ my S Pen wouldn't connect until I restarted with the S Pen out then inserted after reboot was complete. Now the battery indicator is doing some funky stuff. The battery indicator on the Air Actions screen rapidly changes from 100% to 60% then goes back to 100% and 10% increments. It only takes about 2 seconds to go from 100 to 60 back to 100... Seems odd. I restarted my phone, I remove the case... Any help would be much appreciated.
Have you tried resetting the S Pen?
