How to make this no-clip VFX?

So I saw this effect and I know I may do something like just make a 3d model fall but can anyone explain this to me?

Realme 12 screen is dying

After grabbing my phone with my hands wet from salt Walter this happened, i have a realme 12 4G, the black thing is getting bigger slowly. Is it still good to replace screen?
