LG G2 Power button end call issue

[Cobain Sweetheart]

Hi im using an international version of LG G2 that is made in korea D802. Before this i have the same issue but i factory reset it and the power button end call functioning. But then i disabled unused apps like face unlock, cloud hub, google play games. Besides, the prelloaded apps also been uninstalled (power button to end call not functioning anymore, it's just turned off the screen). The only apps that i kept are LG keyboard, LG backup, vutalk, and file manager. so may i know what should i fix? i mean any preloaded apps that related to this issue. Thanks!

Honestly, I am not sure what app would have linked to that. I honestly like the power button not ending the call as I like to lock the screen so I don't turn my head, bring the screen up and then have my ear hang up on someone.
