[Hack] CRT-On Animation for Galaxy Nexus


We’ve all seen the CRT animation that plays when we turn off the screen on our Galaxy Nexus, which was quite an eye-catching feature introduced with the Nexus S and Android 2.3. Now you can make the animation play when turning the screen on as well, using this hack. The Nexus doesn’t have it by default, leaving it to the developers over at XDA to put it in, and that’s exactly what xda dev kamma has done. Read on to find out how to install the CRT-On animation on your Galaxy Nexus.

Be careful though, this hack has only been tested on ICS firmware, so make sure you are on that firmware before trying it out. Also, at this moment there are the following known issues:

  • If you turn off the phone while there is Face unlock screen and then turn on the phone, it occasionally results in reboot.
  • If you turn off the phone while there is lock screen and then turn on the phone, CRT-ON animation will not be played.


The methods and procedures discussed here are considered risky and you should not attempt anything if you don’t know exactly what you are doing. If any damage occurs to you or your device, including a bricked, non-functional device, we won’t be held liable. You have been forewarned!!!
