This happened on a Cebu Pacific domestic flight from Legaspi, Albay to Manila. My sister who witnessed this unbelievable act was seated behind the jerk who was seen using his LG Smartphone, this person used his cellphone 4 times, he was sending Text messages, his phone wasn't even in Flight mode, during in-flight and crucially while landing. She did tap the person using his phone kindly asking him to turn it off but she only got a reply; "Ano pake-alam mo?!" from the guy. After that she motioned to get the Flight Attendant with the call button but by the time the Attendant came the *ssh0le hid his phone away.

Is there is a law/regulation banning the use of Cellular devices and is it punishable by law here in the Philippines? I know in the States the FAA bans this and you could end up in Federal Prison.
