Control what your applications can learn about you and your contacts. Protect
yourself with a simple click, or long press an app to delve deep.

8. Global Blacklist
• Baked right into the OS is the ability to flag telemarketers, robo-callers, annoying
people (yes even the in-laws) and blacklist them. Never receive another call or
message from them (or maybe just ignore them for a little bit).

9. Quick Setting Ribbon:
• Embed quick toggles (and even your camera) right in your
notification drawer, just one swipe away.

10. Quick Settings Configuration
• Whether using the ribbon view or the larger grid view, customize the
layout and order of your quick settings.

11. Status Bar Behavior
•
• Customize your status bar and unlock some additional behavior. Tap the time to
quickly set an alarm or tap the date to access your calendar. Show or hide as much
as you'd like.

12. Profiles
Our lives are always subject to context - what's appropriate at home may not
be at work. So why aren't our devices? With profiles you can control
application, sounds and even connectivity to quickly adapt to the environment
in which you are using your phone. Go one step further and set up a profile to
be location aware, or use NFC to trigger a profile change.

13. Navigation bar
• Why stop at hardware buttons? Customize the software
navigation bar to your liking as well.
13

14. Lockscreen
• Add quick unlock targets to access your favorite apps directly from the
lockscreen. Use our custom lockscreen widget to increase your
productivity. Show the weather and your calendar events without
unlocking the device. Optionally display battery status or even your name
and ICE information.

•
• Useful to developers and users alike, control your exposure to root applications and
debugging tools

17. Advantages
• Common reasons to modify your device's operating system include:
• Remove unwanted programs ("bloatware") installed by your carrier
• Receive more frequent security updates
• Have access to the current version of Android - most carriers take
months to update devices on their network to the latest version of
Android, if ever. Taking control of your OS allows you to update
regularly, when you feel like it's time.
• Better performance
• Extra features
17

18. Disadvantage
• Common concerns include the following:
• Some device manufacturers or mobile providers may offer a limited or voided
warranty after modifying
• It is possible that by installing a rooted operating system, you introduce new
security risks. For instance, you need to be smart about the permissions you grant
applications.
• Non-stock firmware could contain malicious code - which is a good argument for
making sure you download custom ROMs from trusted sources, or even better,
learn to build it yourself!
• Stability issues may arise when using an experimental operating system.
However, for many people, CyanogenMod has proven to be more stable than
many official ROMs.
