display color problem

[Syedfarazaftab]

So i have a problem with the lock screen of the A30s. When i put in display fingerprint on the lockscreen picture colors are over saturated dark like cartoonish, I also found out that when i disable the fingerprint unlocking  method and unlock by either pin pattern or swipe the colors are fine,but as soon as i turn on the fingerprint the colors turn bad again. So i want to know if this is a software issue or its just my device any other people  are having same issue  as mine?
