Display won´t turn off automatically

[Z5thebest]

Hi there!

Display of my Xperia XA1 will not turn off automatically after the set time limit. I noticed this after the latest update 41.A.2.21. I cannot see it related to any app. Does anybody else suffer this issue?

Thanks.

I have the same firmware but I don’t have that issue. Just to be sure, do you know that if you have ‘smart backligth’ (or something like that) on, then the display will not turn off while you keep your phone in your hand, but it will if you place it in a table?

Dear @Jetzu,

thanks for the answer. Yes, you are right about that smart backlight. However, it is turned off. Lately, this problem seems intermittent - it occurs and  sometimes not...

Kind regards.

I have found if you have do not disturb to turn on a set time and when it turns off it sets the display back to default setting Screen Timeout and Image enhancement.
