Just recently, the latest <a href="http://www.cyanogenmod.org" target="_blank">CyanogenMod</a> nightly began supporting encryption on my phone, <a href="https://jira.cyanogenmod.org/browse/CYAN-6670" target="_blank">even though the bugreport still says it's an open issue</a>. I don't mind. Anyway, this allowed me to finish a major project of mine: Protect the data on my phone, even in the case of a theft, while maintaining the ability to use the device conveniently. <b>The goal.</b> I want a strong disk encryption password, but i want a weak screen password or PIN, because unlocking the device is a frequent task. In such a scenario, it makes sense to implement an account lockout policy: In other words, we want the phone to shut down after, say, 3 failed attempts to unlock the screen. This prevents the screen password from being brute forced. Your device needs to be rooted to do everything I did. You will also need the <a href="http://developer.android.com/sdk/index.html" target="_blank">Android studio</a> if you want to do this properly, and it's a large download, you might as well start now. <a href="https://blag.nullteilerfrei.de/2015/11/09/protect-your-android-and-still-enjoy-it/#more-3513" class="more-link">Click here if you're still interested.</a>
