I'm trying this again...asking for help on this problem.
I can't access the Security screen under Settings in Android 4.2.2.
I performed a system update to android 4.2.2 (from 4.2.1) on my rooted LG Nexus 4 - all went well, using Voodoo OTA Rootkeeper to preserve root. Everything works, except one thing. Pressing Settings -> Security gives me the message "Unfortunately, Settings has stopped" - pressing OK takes me out and back to the home screen. I can access all other screens under Settings.
As a further note, I performed the same system update on a rooted Nexus 7 and a rooted Nexus 10 - all without problems and I can access Settings -> Security.
Apps across all 3 devices are basically the same. Thinking it might be a misbehaving app, I reviewed permissions in the most suspect apps and uninstalled/reinstalled each of them one at a time to test my theory. No joy.
Can anybody help me with this...or, at least, give me clues.
