- CM11 has some bugs, but nearly perfect for daily use.
- How to enable developer settings on CM11;
Go to the settings menu, and scroll down to "About phone." Tap it.
Scroll down to the bottom again, where you see "Build number." (Your build number may vary from ours here.)
Tap it seven (7) times. After the third tap, you'll see a playful dialog that says you're four taps away from being a developer. (If only it were that simple, eh?) Keep on tapping, and *poof*, you've got the developer settings back.
****** I don't take any responsibilities if you have any problem about phone. And don't worry , i have install a lot of rom like these style, has no problem yet on me. Good luck and have fun...
