Finally, I got an answer that I went to lockscreen option under Settings, there I changed all possible things i.e., I chose bing as background abd disabled password also quick status apps are removed, where earlier I had whatsapp, email, messaging & call history after removing those apps, made a try to unlock the device by locking the issue explained above in the post disappeared. Yes, it happened.
Thanks to all.
