I use go launcher. I've used it for years between this phone and my s3. Never had this problem. Suddenly when my lock screen is set to swipe as it's always been it acts like I've set it to none. Instead of a screen coming up that I need to swipe to open my phone it just opens. I tried restarting. The first time I pushed a button the swipe screen came up, but doesn't come up anymore. I tried changing it. Screens with a code work fine, switch back to swipe and it doesn't work properly. This started in the last couple days. What's going on?
