HTC One showing notification bar swipe issues, can I get some help?

Hello. I am using HTC One and for the past 2-3 days i am facing an issue related to the notification bar. When i want to swipe it down it does not swipe down and sometimes it automatically swipes down on its own. I did install the system software updated 2 weeks back to Android 5.0.2. Is there any solutions for it ?

Ok, try Safe Mode, which can tell you if it's a 3rd party app causing the problem: https://support.t-mobile.com/docs/DOC-11779
