Samsung S5 display not turning off automatically on lock screen.

[AC Question]

My phone is locked, I get a notification and the lock screen turns on, but then does not turn off automatically. The display just stays on until i turn it off. This is a problem because this morning I woke up to it majorly overheating and took a long time to cool down.
What should I do? this has only started recently

If you have peel remote installed try disabling wigets under its settings. Worked for me.
