Default [Q] Changing Stock Rom Screen density

Hi all,

My new phone did not survive a single day without (towel-)root. So after getting root, I was thinking about changing DPI.

default in /system/build.prop is 480. I changed it to 360 and 420, both seems fine for the GS5. As a scale referenced I used values from - my Galaxy Nexus is running at 246 just fine.

But sadly, the stock lock screen is now shifted left. Any idea how I can replace the stock lock screen with another fingerprint-ready lock screen? A lock screen with 4x4 pattern would also do.

Thanks in advance.

PS: If I have time, I will make a thread similar to the linked above.
