从Android设置界面移除锁屏功能，并默认不锁屏；（但仍能通过第三方软件开启锁屏功能）

1] $ vi ./frameworks/base/packages/SystemUI/src/com/android/systemui/keyguard/KeyguardViewMediator.java

修改点1：
--- private boolean mExternallyEnabled = true;
+++ private boolean mExternallyEnabled = false;

修改点2：

public void setKeyguardEnabled(boolean enabled) {
synchronized (this) {
if (DEBUG) {
Log.d(TAG, "setKeyguardEnabled(" + enabled + ")," +
"called by pid = " + Binder.getCallingPid());
}

enabled = false; // R: add to remove screenlock
mExternallyEnabled = enabled;

2] $ vi ./packages/apps/Settings/src/com/android/settings/SecuritySettings.java

private PreferenceScreen createPreferenceHierarchy() {

PreferenceScreen root = getPreferenceScreen();
if (root != null) {
root.removeAll();
}
addPreferencesFromResource(R.xml.security_settings);
root = getPreferenceScreen();

// Add options for lock/unlock screen
final int resid = getResIdForLockUnlockScreen(getActivity(), mLockPatternUtils);
//addPreferencesFromResource(resid);

3] $ vi ./device/{vendor}/{project}/system.prop
增加下面的语句：

# disable lockscreen
ro.lockscreen.disable.default=true
