Screen flickers when unlocking it

[Saund2002]

Hello guys I have an S5 galaxy and everytime I unlock my phone it flickers green and yellow before showing my lock screen. What should I do, buy a new screen or would it be a faulty connection? My screen has no cracks in it currently.

Thanks in advance

This might be a long shot, but do you have a few apps installed that have permission to change the lockscreen wallpaper and/or screen wallpaper. Perhaps conflicting?

Since the flickering only happens when the screen is being unlocked, not sure it is a problem with the screen.

Nah, I don't have anything on my lock screen but thanks

I'm having the same issue. Please let me know if your figure anything out. I tried wiping the cache, and I tried turning up the brightness. I got a launcher and it actually helped for a month so, I'll get back to you if I find anything
