These are the code snippets:
port settings: I did not include the other port settings
Code: 
ADCON1 = 0x0F;
INTCON = 0x00;
TRISC = 0x00;
PORTC = 0;


I'm using PORTC.F0 up to PORTC.F3. Port F0, F1, and F3 works just fine but at F2 otherwise
I'm thinking it is because of PORTC.F2 is multiplexed with CCP1/P1A. Is it possible to disable this?

EDIT:
The ports activate when a corresponding key is pressed from a keypad
 

Anyone knows what is the problem? Is it hardware or software issue?
