Urgently rolled back the changes to the model's collision box. For unknown reasons, it seems that using a custom collision box causes the game to crash.

Adjusted the model's collision box to match the phone’s dimensions (due to game engine limitations, this change should only take effect on the local server).
Corrected the position of the front camera and the orientation of the screen.
Modified the texture of the Home button by manually editing the UV map to ensure it appears three-dimensional even in the absence of specular reflection.
