Its always very hard to get the kernel code of most MTK devices so if you want to do custom ROMs for that device its a little bit difficult to get everything working properly. Finally Ulefone stepped up and released the android 6.0 kernel code officially for its bezel-less powerful device Ulefone Future thus encouraging developers to customize the device.
If you are a developer who likes to create custom ROMs for devices, I will advice you to put in more of your effort to create a sweet and smooth custom ROM for this device because Ulefone is ready to do a long term partnership with you if your custom ROM has good review among users of this device.
You can download the source code from Google Drive
You can also customize this code directly from Github
If you discover any bug or figure out any new stuff about the code, you can share it on the Ulefone forum
