Unlocking 20/20/20/20 mode
This first cheat brings back the much-missed 20/20/20/20 mode to FNaF4. To do this, you need to have first completed Nightmare mode. Once you’ve beaten it, unlocking this mode is a snap.
Do keep in mind this mode is more difficult than Nightmare mode and the AI is much more aggressive.
Unlocking 20/20/20/20 on PC

Unlocking 20/20/20/20 on iOS and Android
The mobile version of Five Nights at Freddy’s 4 has some differences from the PC version due to hardware limitations, and unlocking 20/20/20/20 mode is different as well.
You do have to complete Nightmare mode just as with the PC version of the game, but you need to do a different trick in the Extra menu.
In the Extra menu, scroll all the way to Nightmare.
Double tap him and you will unlock 20/20/20/20 mode just like on PC.
Other cheats
The Cheats menu can be accessed once you have finished 20/20/20/20 mode. Here there are three total cheats you can enable, all three making the game easier and more convenient to play. These are:
Fast Nights - Makes time move faster, and hence makes each night take less time. House Map - Shows a map of the house at the top right, along with indicators to show you where the animatronics are. This is a great way to see how the animatronics move. Danger Indicator - Enables a warning to tell you when an animatronic is standing behind a door you’re at.
These three cheats are great if you want to play the game a bit differently, or want to go through without so many heart palpitations.
