having issues charging with the original charger since 8.1. When I was in update april patch after the charger stopped after 5 seconds same when phone off and charging it just kept rebooting to charge screen. So rolled back to 8.0 and all fine. Now have 8.1 again and the charger has stopped working again. My switch charger charges phone fine on 8.1. So is there anything I can try to see why 8.1 has stopped orignal Nokia charger Woking ?
