I want Android OS with no usable features, the only task the OS would have is to turn on and redirect the user to a APP.
Here are the steps
1. The user turns on the phone
2. The OS is loading as the phone turns on. When it's on you enter the homescreen.
3. You see the homescreen with a logo as background in a few seconds as the app loads
4. App has loaded and the OS opens the APP
5. The APP opens and inside the app is all the features.
You can now use the phone to it's intended task, and it's not possible to quit the app.
Any suggestion would be helpful?
