My s pen on my not 10 plus disconnects regularly and doesn't charge. It works but the remote feature is unavailable. It reconnects but after some time disconnects. Doesn't charge sometimes. Reseted it many times but same. When s pen is connected the battery percentage fluctuates from 90 to 100 all the time. Issue came after the monthly security update. Do I need to replace the s pen or os it a software glitch?
