Beginner Level 2

Hello

       I have Samsung m21 6gb varientwith latest updated firmware. I noticed some bug in my Samsung m21 6gb varient. Sometimes touch not responds and where ever I touches notification bar is coming down. I cant do anything. I tried turning screen off and on, but nothing happend. But lock screen is responding.

After some time it responded without any probelm. I think it's a serious bug.
