Notification Panel Scroll down not working in HTC One X+ model

[AC Question]

I have a HTC One X+ model phone which I bought 2 years back. From yesterday on-wards the notification panel scroll down is not working from the top direction. It's working if I rotate the screen and pull it from other direction. I have installed some applications before the issue started. So I uninstalled the apps & tried a soft reset, no hope. Can anyone help with a solution.
