The GTA franchise is known for its cheats as much as its violence and cars. In the early console versions of the game they appeared in-game as button combinations, to be entered during regular gameplay in order to activate their effects. Then when the current-gen and PC version of GTA V launched, they brought with them a new way of using the iconic cheats.
If you pull up your character's phone, and punch in the right number, initiating the call will trigger the associated cheat. Most phone cheats are the same as regular cheats, however some unique easter eggs have also been added by Rockstar that are phone exclusive.
Recently a new phone cheat named "Black Cellphones" was discovered. If you called the associated number, the numbers of which spelled out EMP-DROP, a small explosion would occur right in front of you, and the phone will turn black. Speculation as to the reason this exists lead to the rise of new rumors.
Black Cellphones isn't the only new cheat to be discovered this week, however. Until now, a few of the regular cheats still didn't have phone numbers or PC keyboard combinations assigned to them.
