[issue] LOCKSCREEN malfunction

[Emmanuel Ezenwa]

Every time I unlock my phone from the lockscreen, it brings me to this black screen for second or 2 and then to the application I was using before(ex. Instagram). This happens primarily when I put in the wrong pin or pattern on accident. My question is how can I remove this little annoyance? It happened when I was running Cyanogenmod, Omni, and PA. So I decided to un-root my phone and re-root it again, only to see that the problem is still there after a little while of using it. Currently I'm running a stock rom+unlocked bootloader+custom recovery(TWRP)

note: the issue still occurs in safe mode

Thanks and have a great day!
