Here I have Samsung Galaxy A3 and let me show you how to add a screen lock protection on
0:10
the following device. At the very beginning let me start by using my home screen, let me find and select the
0:16
apps icon right here, let me choose settings, let's scroll down and choose lock screen and
0:23
security right here. Then let's choose screen lock type and as you can see here you should decide that you
0:29
would like to choose swipe, pattern, pin or password. Let me choose pattern in my case, let's draw your unlock pattern, tap continue and let
0:37
me do it again just for confirmation. And now we have to set the backup pin so let me just use the simplest one 1234 as an example only
0:49
Now you have to choose your form of notification, you can choose show all content, hide sensitive
0:54
content or don't show notification at all. Let me use show all content and tap done
1:00
That's it, you can change some settings about the screen lock or you can simply go to the
1:06
home page and let me use the power key. Now if you would like to unlock your device you have to enter your pattern so let me do
1:14
it and now you may use your phone. So everything went well, thank you for watching, please subscribe our channel and leave thumbs
