How do I get rid of the two lock screens on my Galaxy Grand Prime? Today I woke up and noticed I have to swipe not just one but two screens. The photo is the new screen that is completely unwanted. 

After I swipe on that one, I enter my normal lock screen and have to swipe and put in my code like I do usually. 

I have only Snapchat, Facebook and Facebook messanger apps. The rest of the weird apps android comes with have already been disabled or uninstalled and I haven't made any changes since I got the phone. Which was like a week ago. 

How to I get rid of it. I do not know where it came from. It is super annoying have to swipe two screens and plus it have this black square on the first screen and it won't go away. Please help. 

Thank you.
I had similar issue and it turned out to be a launcher that I installed to change wallpaper. Needless to say I uninstalled it. Lol
