Note 10+ spen disconnected problem

You have to check is there any damages in SPen. Hope you already did "reset S pen" as shown in the attached screenshot. If not try once. Even it's not connected then its SPen fault. You have to go to service center for physical inspection

For me it happened once on another note.. A toggle to airplane mode n back fixed it..

It must be s pen problem so s pen will be change
