Perfect – Portrait Blur - Free Lens and Depth Effect Bokeh Review

used this app on other devices long ago and now I am using it on my redmi note 5 pro, where if I try to set portrait photo on both lock screen and home screen Or just on the lock screen, it doesn't happen and the lockscreen portrait photo doesn't change.
