See if you have other features that would make screen timout , like Samsung phones have smart stay if you don't look at the phone it will close it

Welcome to Android Central! Where did you set the timeout to never? Most phones don't let you do that.

Got a PM from new member @LarryHolbrook who was having trouble responding to this thread:

"I had the same problem - I disconnected the charging connection and it stopped 'auto-dimming' -

I have an AT&T LG K40"

Thanks, Larry!

Thanks B Diddy for posting that - I couldn't make the post myself -

More time went by and 'auto-dimming' returned -

I'm not certain that was 100% of the problem - I'm thinking somehow the condition of the battery or the battery charge may have something to do with the 'auto-dimming' -

Hi, welcome!

You use any extreme battery save modes ?

 

[LarryHolbrook]

I really don't know much the AT&T LG K40 or phones in general - I just noticed that the 'auto-dimming' stopped when I removed the charger - it did return later and I can't remember how long the 'auto-dimming' stay stopped - at the minute, with the charger connected, it's not 'auto-dimming' right away in 5 seconds like it was -

My battery saver is off and the adaptive battery is on - there are a dozen or so battery saver exclusions which were set by the system which I can't change and two that I set, Alarm Clock Extreme & Contacts - but like I said the battery saver is off -

I was really hoping my comment might 'trigger' a thought by a phone expert that would actually figure out the problem -

You have developer option enable ?

 

[LarryHolbrook]

Developer Options are not enabled on the AT&T LG K40 -
