After one ui 8.5 update my battery is draining faster, I have not installed new apps and not even playing games more than before, just fix the problem

I was using the new feature of Good Lock app which helped me with the widget to used on lock screen to use a picture from gallery so that I can make my lock screen clock with depth effect but suddenly today the imageshowed out of shape

Since one ui 4 update on my mgalaxy s20 fe, portrait mode of camera not working properly. While watching in camera all the filters are seen but the final output of the image is normal.

Network problem of going off and coming back often still exsist, and no response from samsung team till now, dint expected this from samsong.
