Secure screen lock android: Security Lock Screen Beta

I want to use a secure lock in android
This post is not about global security: I know that USB debug should be disabled in order to avoid screen lock bypass...

I just want to have a good screen lock. I have installed personal certificates and slide is not allowed, but I do not like just pin, password and just 3x3 pattern

In badadroid, with CyanogenMod, I was using 6x6 pattern, with CyanLock ... but CyanLock is not available in other ROMs.


I do not want change just the look

My objectives are:
1-Avoid camera and widgets
2-Avoid pin and password: too long for a simple unlock task: some kind of pattern more complicated

For 1, I find this, that should do it:

https://play.google.com/store/apps/details?id=com.wordpress.chislonchow.deviceadminkeyguard

Tested and ok

And for 2, maybe this app... but is in korean language!
https://play.google.com/store/apps/details?id=com.lsh.kwj.secure.lock.screen


I find this
https://play.google.com/store/apps/details?id=co.kr.generic.ocr_kor
And after testing it with some of Google Play's screenshots... I dared to install it
And I finally find it already translated to English

Two things:

It is mandatory to configure this app as primary launcher, and the previous launcher as the second one. 

In this way it works with any ROM, but, it will be possible somehow to add another option in settings > security > Screen lock ?

This app says "If use system lock, double-lock. If you not want double-lock, press button and select None"

However, "Disable System Lock" button do not start settings to disable it, and I am not able to do it, because I have installed a PKCS 12 certificate, and I see this.

"None. Disable by administrator, encryption policy, or credential storage"So after pattern, I  have again previous pin.

Clearing credentials, it works, I configure a 6x6 pattern, and it is mandatory a Backup PIN

I see that previous app is not necessary any more: enabling camera and widgets there are disabled with this app.

To remove it, I must disable it previously in settings > security

Where I see what does it mean to activate it for this new app

One more thing: I disable Clean Master Floating widget, as it appears over this "screen lock" (you can see it in the right margin in previous screenshots)

After that, final result
The status bar is not available, as expected, so I need some workaround for a screenshot

$ adb shell screencap -p /storage/sdcard1/screen.png* daemon not running. starting it now on port 5037 *
* daemon started successfully *
$ adb pull /storage/sdcard1/screen.png
688 KB/s (58859 bytes in 0.083s)
$ adb shell rm /storage/sdcard1/screen.png

Update: somehow, whatever status I have, checked or  unchecked, in "Enable Statusbar in Lock Screen", I am able to scroll down status bar.
Anyway, if I check "Enable full screen", it is imposible to scroll down status bar, so it disable it ok.

I check that the reason is to have as "default launcher" Cool Launcher, not this app, but there is no the option to change it!?
Uninstalling and instaling again the app, I configure it again as default laucher and "Enable Statusbar in Lock Screen" works again as expected.

Comments:
-I see some bizarre behaviour when screen locks while writing in gmail app...  it doesn't allow to unlock, but it allows to input data !
-And language is English in date, ignoring locale (SAT instead óf "Sáb")

Update: there are some mistakes: "TUR" instead "THU" for Thursday.
