Hi, my screen flashes for 0.5secs at full brightness when I try to unlock any app using fp and thing happens on AOD also. 

I tried booting into safe mode no luck.

Hi ajaykadian99, we suggest you to perform safe mode. IN Safe Mode, your phone will not run any third-party apps. This allows you to easily identify and remove the app that may be causing the problem.

To enter Safe Mode, please perform the following:

1.First, completely power off the phone.

2.Then, power on the phone and when the Samsung logo appears, press and hold down the Volume down key.

This thing happens with AOD also. Tried Safe mode thing no luck still there.

It looks like a software glitch or Hardware problem

Maybe software. Just bought the phone 4days back.
