* I am not responsible for bricked devices, dead SD cards, thermonuclear war, or you getting fired because the alarm app failed.
* Please do some research if you have any concerns about features included in this ROM before flashing it!
* YOU are choosing to make these modifications, and if you blame me in any way for what happens to your device, I will laugh at you.
* BOOM! And Turn to Ashes...!!!

What's ColtOS

ColtOS Project is presented by a team of learners and it is crafted from AOSP Source with all the necessary customizations, without compromising the stability and security of the device.

We have cherry-picked the features from many other roms/projects and we are very thankful to all of them!! We just crossed the Beta Phase for Oreo and are happy to announce the release of Colt-OS Chilly based on Android 8.1.

Although there's no bugs experienced by us or testers, if you find any, please let us know with a logcat.
