John : Let me explain the abbreviation of the picture above. 
A = Antenna 
R = Register (WhatsApp)
PL= Parallel input output line
CL = Clock line
.
John : Parallel line is the branch of Clock line.
Me: Ok.
John: Kelvin press a button.  My WhatsApp App black screen. 
Me: Ok. 
John: I suspect that Kelvin hack my WhatsApp app through "Mobile data". So, I close the mobile data. Guess what happen.  
.
Me: What ?
.
John : Kelvin click a button again.  My WhatsApp app still black screen. 
.
Me: It's strange.  Here is no mobile data now.  Kelvin still can let your WhatsApp black screen.
.
John: I close the mobile data.  However,  my antenna still receive data.
Me: What data?
John : Receive telephone data. 
Me: To totally stop Kelvin from letting your WhatsApp black screen,  you gotta close the SIM Card.  That mean,  you need to shut down the Antenna.
