class Mobile

Moves the character's finger in a swiping motion when holding a cellphone in their hand through the use of the CREATE_MOBILE_PHONE native.

enum eCellInput {
    CELL_INPUT_NONE = 0,
    CELL_INPUT_UP = 1,
    CELL_INPUT_DOWN = 2,
    CELL_INPUT_LEFT = 3,
    CELL_INPUT_RIGHT = 4,
    CELL_INPUT_SELECT = 5
}

if the bool "Toggle" is "true" so the phone is lean.  
if the bool "Toggle" is "false" so the phone is not lean.  

This one is weird and seems to return a TRUE state regardless of whether the phone is visible on screen or tucked away.  
I can confirm the above. This function is hard-coded to always return 1.  

Activates the cellphone camera. Make sure you have a mobile phone created with CREATE_MOBILE_PHONE or else the camera will not work.

Toggles the selfie mode on the cellphone camera. Only visible when the cell phone camera is active.

Creates a mobile phone of the specified type.  
Possible phone types:  
0 - Default phone / Michael's phone  
1 - Trevor's phone  
2 - Franklin's phone  
4 - Prologue phone  
These values represent bit flags, so a value of '3' would toggle Trevor and Franklin's phones together, causing unexpected behavior and most likely crash the game.  

Destroys the currently active mobile phone.  

If bool Toggle = true so the mobile is hide to screen.  
If bool Toggle = false so the mobile is show to screen.  

Toggles depth of field on the cellphone camera.

Last parameter is unknown and always zero.  

The minimum/default is 500.0f. If you plan to make it bigger set it's position as well. Also this seems to need to be called in a loop as when you close the phone the scale is reset. If not in a loop you'd need to call it everytime before you re-open the phone.
