Is there a permanent screen locker replacement for the Samsung Galaxy S5?

[AC Question]

Samsung Galaxy S5 setup permanent screen locker replacement

Hi all,

i'd like to know if there is, and how to set it up, a screen locker for Android that lets me quickly check all notifications and access some system settings eg: wifi, torch, camera, data, gps, ... iOS-style. I don't want to unlock my phone to turn wifi on/off or read the Facebook message I just received.

To unlock the screen, I'd like it to ask me for a pin/pattern/whatever and I would like it to fully replace the stock Galaxy S5 locker.

I would like not to root my phone too.

I tried Go locker, but since I had set up a PIN to unlock my screen, I would have to first swype up to unlock Go locker, then enter the PIN to actually unlock my screen.

I tried the "PIN" setting from Go locker settings, but it changed nothing.

I also noticed some lag in waking Go locker when pressing the power button, ie: I saw the default lock screen coming up and then Go locker screen appearing.

Do you have any suggestions?

Thank you in advance,

have a nice day
